Installation instructions for a 4 section in-ground batting cage from PracticeSports.com.

There are a variety of different "packages" available. These are available at a relatively low-cost by buying sectioned kits.

Layout position of frame uprights using
wooden stakes. Equally space the uprights, for 57ft
frame 19ft on center. Be sure to x measure the
outer two ends, this will ensure the layout is
equally squared. This dimension will be 59ft. These
measurements are center to center.

Dig holes for upright support sleeves
approximately 16"-18" in diameter for 2-3/8"
frames or as needed for all frame applications
based on soil conditions. If
you have loose/sandy soil,
concrete diameter should
be a minimum of 16-18" for
all frames. Holes should be
24" deep. Insert sleeve with
cap into hole. Fill to ground
level with concrete before
concrete has set. Check distance of sleeves from center to center. Be sure
to level all uprights by gently setting upright into
sleeve.

Once the concrete has set, install all
uprights and crossbars with the aid of an
assistant. Tighten all set screws.
