Permanent backstops are constructed by installing supplied 2-3/8" pipe supports approximately every 10′ in concrete footings as shown on installation drawings provided. You then simply bolt pre-fabricated 5’H x 10’W panels in place to create your finished backstop. No more cutting and stretching chain link material in the field. These backstops are extremely durable and allow individual panels to be removed for re-screening or replacement as needed. 5′ x 10′ panels are composed of 1-5/16" OD galvanized tubing with center reinforcing brace and 9 gauge galvanized woven wire.
