National Loop Co. 17' (2.5' X 6') Direct Burial Vehicle Detection Loop with 20' Lead-In for 8.5' Wide Driveways - K-NL8.5-14-20

Placed before the paving crew arrives, the National Loop Co. 17' Direct Burial Vehicle Detection Loop with 20' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. 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. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. Its 6' side spans the travel lane while the 2.5' side runs in the direction of traffic, leaving roughly 1' 3" of clearance on each edge, an arrangement well suited to older urban row homes, narrow driveways, and single-car gravel drives in rural areas.

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
