Chain Link Backstop-20' w/Hood & Wings 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 factory pre-fabricated 5' x 10' 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. 20' x 10' with hood and wings.
