For indoor installations the cables are generally attached and tensioned between walls, or from eyebolts that are installed into ceiling rafters. And for outdoor installations the cables are most typically tensioned between some poles or posts that have been set into ground. The general recommendations for either type of installation is to locate the cables so that they line-up with the dimensions of the batting cage net that is being suspended. This means that there is usually 3 cables for an average sized net: one for each side, and one running down the center.
For additional context on this, reference the following article that is also on this blog:
A recent Gourock batting cage customer documented his installation, and sent us this great photo portfolio of the construction process and materials that he opted to use. This is a residential batting cage installation that utilizes the cable suspension technique, and features a custom footprint/bed for the batting area and a unique clamping mechanism to secure the wires to the square steel support poles.
The netting is a #42 HDPE Batting Cage Net, 12' high X 14' wide X 55' long. This net has a physical weight of 100 lbs.
As you can see from the end results of this project, he also added a lighting system for nighttime practice.
This is a really great setup, and a fantastic construction design - thanks again Mike!
