This Marsh Saw-Cut Loop Kit includes enough wire to give you a 1.5-foot-by-4.5-foot loop and comes with a standard 20-foot lead-in. Also included are foam backer rod to hold the wire in place and a tube of polyurethane sealant to close up the channel cut in the pavement for the loop.
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 wire is wound into the channel, topped with the backer rod and the sealant is applied to lock the loop into the pavement.
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.
