National Loop Co. 17' (2.5' X 6') Direct Burial Vehicle Detection Loop with 75' Lead-In for 8.5' Wide Driveways - X-NL8.5-14-75

Because it ships fully assembled in heavy-duty conduit, the National Loop Co. 17' Direct Burial Vehicle Detection Loop with 75' Lead-In is ready to lay down the moment the sub-base is graded. 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. With the 6' side crossing the lane and about 1' 3" of clearance per edge, and the 2.5' side capturing vehicles in the direction of travel, the layout fits older urban row homes, narrow driveways, and single-car gravel drives in rural areas.

Features:

• 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
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
