National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with 75' Lead-In for 11' Wide Driveways - K-NL11-14-75

Made for new paving projects, the National Loop Co. 22' Direct Burial Vehicle Detection Loop with 75' Lead-In is a factory-wound 14 AWG loop that installs flat on the graded sub-base. 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. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. Its 7' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to slightly wider suburban single-car drives and older neighborhoods with wider lot cuts.

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
