National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 250' Lead-In for 21' Wide Driveways - X-NL21-14-250

Designed to be paved over, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 250' Lead-In is a preformed 14 AWG inductive loop for new-surface installations. Paired with a compatible loop detector, it senses the metal mass of a passing car or truck and signals the gate operator to open, hold, or reverse, providing one of the two means of entrapment protection UL 325 requires for automated gates. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. Its 15' 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 2-car plus guest parking and wider rural/farm gate entrances.

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
