National Loop Co. 17' (2.5' X 6') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 8.5' Wide Driveways - K-NL8.5-14

The National Loop Co. 17' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a 14 AWG inductive loop that arrives preformed and ready to install, with its lead-in attached as part of the same continuous wire. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 6' side spans the travel lane while the 2.5' side runs in the direction of traffic, leaving roughly 1' 3" of clearance on each edge, an arrangement well suited to older urban row homes, narrow driveways, and single-car gravel drives in rural areas.

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
