Wheelhouse Batting Cage Details

Below are some brief paragraphs describing some of the batting cage details of a Wheelhouse batting cage.  Such things as shape, overall design, and type of netting to name a few.  If you can't find answers to your questions on this page or others please contact us.
Dimensions

Batting Cage detailsThe cage is trapezoidal in shape:  10' tall, 10' wide at the top, and about 14' wide at the bottom.  The poles are 3/4" EMT - Electrical Metallic Tubing or simply electrical conduit.  The trade name is "thin wall."  The poles are 10' long metal pipe, EMT is stamped on the side of each pole.  They are available at hardware and electrical supply stores such as Home Depot or Lowe's.  You buy the frame poles locally.  The L-screen is 6.5' tall by 7' wide with a 3'x3.5' cutout.  The L-screen poles are included.  You just have to buy the 10' frame poles.

 
Design

Net Over the FrameThe netting drapes over the frame.  It is not attached anywhere to the frame.  As a result there is less wear and tear and abrasion on the net.  Anywhere the ball can hit the net the net can give.  While the frame poles are strong enough to hold the system up, there is no ricochet.  It is based on the principle or "The Law of Conservation of Momentum" which 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 pole has zero momentum.  After the collision the total momentum is the same.  But if the pole cannot give at the time of impact the final momentum of the ball will be about the same as the initial momentum of the ball.  Thus there can be tremendous ricochet and this is very dangerous.  We use 3/4" EMT on purpose.  The poles are strong enough to hold everything up, yet they have flexibility to absorb the momentum of the batted baseball so the ball just dies and falls to the ground.

 
Netting

21net4We only use knotted nylon.  Our mesh size is 1 7/8" on a side.  We do not use poly net.  Knotted nylon is much stronger than poly net.  Knotted nylon is between 72% to 125% stronger than poly net.  While poly net is cheaper you would have to get about a #42 poly to be almost as strong as our #21 and by then you have spent more money.  Knotted nylon is strong, water resistant, UV protected, and will last for years.  The #21 gauge has a burst strength of about 209 pounds per strand or about 836 pounds per mesh.  The #36 gauge has a burst strength of about 380 pounds per strand or 1520 pounds per mesh.  Our netting hangs on the diamond, not on the square.  This allows for more give when hit by a ball so there is less chance for tear and less abrasion.  It also allows water to run-off more quickly.

 
What we send you

BoxThe box will contain the cage netting, cage connectors, L-screen netting, L-screen connectors, L-screen poles, extra twine, packing slip, copy of your invoice, and assembly instructions. You will receive one box approximately 42" long by 17" wide by 17" tall.  The box will weigh between 80 and 150 pounds, depending on length of cage (40', 50', 60', 70') and gauge of twine (#21 or #36).

 
What you have to buy

EmtYou will have to buy the 10' poles for the frame. UPS only ships up to 9' and the frame poles are 10' long.  Shipping the poles would add hundreds of dollars to the shipping cost. The poles are 3/4" EMT (electrical metallic tubing), standard electrical conduit. The trade name is "thin wall" and they are readily available at Lowe's or Home Depot.
