National Loop Co. 72' (6' X 30') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 36' Wide Driveways - X-NL36-14

Built for sites where saw-cutting is not an option, the National Loop Co. 72' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a preformed 14 AWG loop encased in liquid-tight conduit. 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. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 30' 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 truck yards, heavy equipment facilities, and agricultural processing entrances.

Features:

• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
• Factory-set turn count means optimal read range without any on-site adjustment
• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
