The Marsh Vehicle Detector and 1.5-foot-by-4.5-foot Preformed Saw-Cut Loop Kit are designed for vehicle detection installations whose paving has already been poured.

The Vehicle Detector is an intelligent, extremely flexible product. It is designed to intelligently adjust to environmental conditions, virtually eliminating false detection.

The Preformed Saw-Cut Loop Kit consists of multiple turns of wire, bundled together to form a 1.5-foot-by-4.5-foot easy-to-install loop. Also included is a tube of polyurethane loop sealant to close up the channel cut in the pavement for the loop.

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.

If your paving hasn't been installed yet, the Marsh Direct Burial Loop and Marsh Vehicle Detector is a better choice.
