National Loop Co. 36' (6' X 12') Direct Burial Vehicle Detection Loop with 75' Lead-In for 18' Wide Driveways - K-NL18-14-75

Built for sites where saw-cutting is not an option, the National Loop Co. 36' Direct Burial Vehicle Detection Loop with 75' Lead-In is a preformed 14 AWG loop encased in liquid-tight conduit. Wired to compatible automated system, the loop counts as one of the two means of entrapment protection UL 325 requires for gate operators, detecting the metal of any vehicle over the sensing area so the gate stops or reverses before contact. Since the conduit protects the wire, the loop sits directly on the sub-base and gets buried under the new asphalt, concrete, or gravel surface. Its 12' 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 roomy 2-car driveways and small commercial entries.

Features:

• 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
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
