National Loop Co. 80' (6' X 34') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 40' Wide Driveways - K-NL40-14

Because it ships fully assembled in heavy-duty conduit, the National Loop Co. 80' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is ready to lay down the moment the sub-base is graded. 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. 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. Its 34' 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 distribution centers, heavy equipment dealerships, and semi-truck yards.

Features:

• 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
• Saves labor cost compared with winding a loop by hand in the field
