National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 20' Lead-In for 21' Wide Driveways - X-NL21-14-20

Sized to match a specific driveway width, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 20' Lead-In is a factory-wound 14 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. Installation is a lay-and-pave job: set the loop on the graded sub-base, run the lead-in to the detector, and let the paving crew cover it. The 15' side covers the travel lane with roughly 3' of clearance on each side, and the 6' side reads vehicles as they roll through, making it a fit for 2-car plus guest parking and wider rural/farm gate entrances.

Features:

• 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
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
