National Loop Co. 40' (6' X 14') Direct Burial Vehicle Detection Loop with 75' Lead-In for 20' Wide Driveways - X-NL20-14-75

Designed to be paved over, the National Loop Co. 40' Direct Burial Vehicle Detection Loop with 75' Lead-In is a preformed 14 AWG inductive loop for new-surface installations. Once a loop detector reads its signal, the loop covers the non-contact vehicle detection that UL 325 requires as one of the two means of entrapment protection for automated gates. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. Its 14' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to ranch entrances, farm properties, and estate homes with dual swing gates.

Features:

• Predetermined number of turns removes the guesswork of achieving optimal read range
• Saves labor cost compared with winding a loop by hand in the field
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
• One continuous, non-spliced wire runs through the loop turns and lead-in, eliminating splice failures
• Liquid-tight conduit stands between the wire and sharp stones, chemicals, ground movement, and harsh weather
• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
