This Marsh Preformed Saw-Cut Loop Kit consists of multiple turns of wire, bundled together to form a 5-foot-by-12-foot easy-to-install loop. Also included are two tubes of polyurethane loop sealant to close up the channel cut in the pavement for the loop. The loop comes with a standard 20-foot lead-in; lead-ins of up to 100 feet are available.
A concrete saw is used to cut a rectangular pattern in the concrete or asphalt. The one-piece loop is set into the channel, and the sealant is applied with a caulk gun.
The standard lead-in length is 20 feet; if you want a longer lead-in, use the drop-down menu to specify the length you desire.
