National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 75' Lead-In for 21' Wide Driveways - E-NL21-18-75

Sized to match a specific driveway width, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 75' Lead-In is a factory-wound 18 AWG loop for pave-over vehicle detection. 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 15' 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 2-car plus guest parking and wider rural/farm gate 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
