Q:
(Recently, this seems to be the most frequently
asked question) What size cage should I buy?
A: That is a tough one for me to answer. I
don't want to say "buy the larger one" for fear of
folks will think I'm trying to sell them more. So I
give them my "two cents worth", and you know what
they say - you get what you pay for! When I started
this business my son was already in high school. We
made ourselves a 50' cage and it worked fine. I was
the pitcher as my son didn't like pitching machines.
Once in awhile, not often but on occasion, when I
would reach back to throw my hand would catch the
back of the net. If I had it to do over again, I
think I would make ourselves a 60' cage. It would
have given us a little more flexibility to move
around - but my son was already in high school. For
younger kids, I do recommend a 50' cage. Their
pitching distance is only about 45-46', so 50' would
work just fine for them. The nets seem to be lasting
between 5-7 years before some repair. So if you
can't use the extra distance for 4-6 years, stay
with the smaller cage. You may want to replace the
net in 5 years anyway. The tough age is the 13-14
year old. They are on the bubble. They certainly can
get by with the 50'er for a few years, but may want
to get a longer distance before the 5 years are up.
An advantage of going longer is you can always put
up less. But if you can't use it for several years
and the net is just lying on the ground, that is a
waste too. Another thing to keep in mind is for
batting practice you don't need to be at regulation
distance. You are mainly working on bat speed,
hand-eye coordination, and mechanics. Quite a few
coaches do a lot of soft toss and you don't need a
long distance for that. I'm afraid I end up my
discussion leaving the client more confused than
when they first asked the question!

Q:
I lost or misplaced my assembly instructions. Can
you send me a copy?
A: Here are the
assembly instructions.

Q:
With the netting on the outside of the poles, isn't
there more chance for ricochet and injury?
A: No. Because of the flexibility of the EMT
poles there is more give, so the ricochet is
considerably less than with 2" steel poles set in
cement. In actual use since 1998, when the ball
strikes directly on a pole it simply dies. Because
of the give in the poles, the batted ball's energy
is absorbed. In fact, I'd be concerned about systems
where the net is suspended from inside the frame.
I've seen many systems where the roof netting is too
close to the roof poles. If a ball hits the roof
pole, the netting is between the ball and the pole,
thus much more abrasion on the net. Plus these types
of poles are a lot stiffer hence a much greater
chance for ricochet.

Q: How much does
it sag?
A: A few inches. With cages where the netting
is hung on the inside there is tremendous sag. This
is why most traditional cages are a minimum of 12'
high in order to have about 10' of clearance inside
the cage. In addition, because of our design, there
is much less tension and wear at the corners and
middle. The weight is evenly distributed over the
entire width and length of the cage adding to the
life of the netting.
Q: Is it
sturdy? It looks flimsy.
A: Don't confuse "flimsy" with "flexible."
You won't be able to do chin ups or shimmy up the
poles, but the system is very sturdy. It is strong
enough to support the netting and take the beating
of the batted balls. Some clients have said at first
appearance the frame looks "flimsy", but after
trying it out, they realize how sturdy and strong it
really is. Some of my competition have suggested
that our system is weak and because of that we "have
to put the legs out at an angle." Sorry, but they
just don't understand physics. The sheer forces on a
rectangular shape are much stronger and put a lot
more stress on the connectors than on a trapezoidal
shape. In addition, the connectors are made of steel
and the angled joints are welded. The #21 is rated
at 200 lb. breaking strength per cord or 800 lb. per
mesh. In fact, I've had clients leave their cage up
during a hurricane (something I certainly don't
recommend) while many poles were bent the netting
and connectors were fine.

Q:
What about knotted nylon vs poly net (hdpe, etc.)?
A: I use knotted nylon only. It is personal
preference, but I think knotted nylon is much better
than any poly net. I used poly for my very first net
in 1998. It curled a lot. You need a much higher
gauge of poly net to have the same strength as
knotted nylon. While it is true that eventually
knotted nylon will deteriorate due to the UV from
the sun, my clients are calling me saying they are
getting 5,6 even 7 years of use from their net
before they need some repair. As a consumer you need
to beware and compare when you buy a net. Make sure
you are comparing apples to apples, so to speak.
Poly net is cheaper than knotted nylon. Here is what
my netting supplier told me:
- PE has lower breaking strength of grams per
denier. This means that the same twine diameter
will not be as strong as nylon. In addition, PE
is bulkier and therefore making the net about 30
percent weaker for the same diameter twine. This
means if the customer is supposed to get the
same breaking strength the twine will have to be
30 percent larger. If you take this difference
into account the price per lb of breaking
strength is not as low as it is promoted. Most
of the companies selling baseball batting cages
in PE are offering the same diameter, not the
same breaking strength.
- Nylon is softer and can be put away in a
smaller package than PE.
- Due to smaller diameter nylon will have less
wind resistance than PE.
- Knotless netting can be repaired in much the
same way as knotted netting. However, since you
are making knots in knotless netting the repair
can be seen easier.
- Depending on the grade of PE being used the
UV stability can be very poor. It really will
depend on the quality of yarn in the net.
- PE netting has no memory. This means that if
the net stretched due to excessive weight or
high winds it will be baggy. Nylon netting will
move depending on the humidity level in the air.
In damp environment it is bigger and as the sun
dries it will contract.

Q: Can it be
used indoors?s?
A: Yes. The only consideration is the floor
upon which you are setting the cage. You may need to
put rubber cups (not supplied), slit and squeeze
tennis balls, or even duct tape over the ends of the
poles to protect the floor. However, when it is
indoors you will have a free-standing system not
requiring pulleys, cables or anything attached to
the walls or ceiling. A lot of colleges and high
schools use our cage as an extra indoor hitting
station, especially in the winter.

Q: How
quickly does it go up?
A: Amazingly fast! After some practice, two
people can put it up in about 20 minutes, even we
were surprised. The very first time may take a
little longer, but once you attach all the
connectors simply leave them attached to the poles
that go across the top. The only tool required is a
7/16" wrench or socket used to bolt the poles into
the connectors. If you desire to bolt the legs into
the connectors, you will need to stand on a ladder.
I have put up the cage by myself. It has been up for
months at a time without the legs even being bolted
into the connectors. If you have your team help, it
can go up in minutes.

Q:
If you are using a pitching machine, don't you need
a stronger backdrop behind the batter?
A: I don't think so. I have very little
experience with pitching machines; however, one of
my clients wrote and told me he tried to put up a
backdrop. He said it acted like a sail so he took it
down. Since the netting can give, not having a
backdrop is better. The net gives everywhere and so
there is less abrasion and wear and tear on the net.
If you still want something, I suggest an
inexpensive piece of carpet or extra piece of
netting as a baffle.

Q:
Don't balls skip under the netting?
A: Occasionally. The netting is about 36'
wide and the frame perimeter is 30', so there is
plenty of overhang. However, if the ball is hit just
right - at the point where the netting and ground
meet there is the possibility of the ball skipping
under. This doesn't happen that often. You can
purchase leaded rope, or any poly rope, or even a
garden hose and lace the bottom edge to give a
little extra weight so the net will stay on the
ground. I have not heard of any complaints from my
clients about this problem.

Q: Can it
be used for softball?
A: Yes, even though the L-screen is designed
for overhand pitching. The girl's softball team, at
the high school where my son attended, purchased a
50' system. They stand behind the "tall" part of the
screen and pitch around the edge. It seems to work
ok.

Q: Since the cage is not fastened down, what about
wind?
A: Wind is the one weakness of the system.
Since it is a free-standing light weight system,
unless the cage is anchored down, high winds can tip
the cage over. Here are some solutions to solve the
wind problem:
- Solution #1: If the winds are
temporary, simple take the net off the frame
during the high winds and lay it on the ground.
The frame doesn't care at all about high winds
(there is no resistance).
- Solution #2: Under the netting, tie a
rope on each roof corner connector, run the rope
parallel to the leg, then anchor it in the
ground with a tent peg or stake. Put the stake
or peg into the ground at a sharp angle with the
leg so it won't be pulled straight up out of the
ground due to a strong wind. If you have a 70'
cage, you may want to tie down one of the middle
legs on each side. This will hold the frame to
the ground and keep it from swaying and tipping
over in strong winds. This has the added
advantage that only the frame is anchored to the
ground, so the netting is still loose and not
anchored to the frame.
- Solution #3: Use ree-bar or something
similar about 1.5' to 2' pound into the ground
next to the leg poles. Drill a small hole in the
leg pole about 6"-8" up from the bottom and run
a wire through the leg pole and around the
ree-bar.

Q:
Does the netting shift after use, since it isn't
tied down?
A: Yes, it can. Wind can cause it to shift.
It can also shift after quite a bit of use if you
have older players (high school or college) that are
strong hitters. Here is a suggestion to keep the net
from shifting "too far" on you. Take a 2-3' bungy or
length of rope or twine. Tie one end on the corner
roof connector. Leave 2' of bungee or twine and tie
the other end on the net corner. Do this on all four
corners. This will still allow the net to give but
it won't shift too far on you.

Q: Is #21 strong
enough?
A: Yes. Unlike traditional cages, our netting
gives on impact. Thus, there is less abrasion and
stress on the netting. The physics of my design is
based on the Law of Conservation of Momentum. (Here
are some details for those who are interested. The
Law of Conservation of Momentum states: The total
momentum of a group of objects is the same after
they interact as it was before. Momentum of an
object is its mass times its velocity (p=mv). Before
collision, a batted ball has positive momentum and
the net has zero momentum. After the collision the
total momentum is the same. But if the net can give
at the time of impact the initial momentum of the
ball is shared between the ball and the net. The
more the net can give, the more the momentum of the
ball is reduced after the collision. A good analogy
would be that of trying to catch a tossed egg. If
you stick your hand up and don't move you will most
likely end up with egg on your face! If you allow
your hand to move with the egg you can catch it and
the egg won't break. With traditional cages, the net
is tied or anchored at several points to the frame.
This prevents the net from giving whenever the ball
hits the net at or near the anchored points. As a
result, at the point of impact there is tremendous
force and if the net cannot give it may tear. If it
doesn't tear, the abrasion is much greater and will
wear down the netting much more quickly. Thus most
traditional cages require (or strongly suggest) that
you use #36 netting.
