National Loop Co. 56' (6' X 22') Direct Burial Vehicle Detection Loop with 50' Lead-In for 28' Wide Driveways - X-NL28-14-50

Placed before the paving crew arrives, the National Loop Co. 56' Direct Burial Vehicle Detection Loop with 50' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. 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. 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. The 22' side covers the travel lane with roughly 3' of clearance on each side, and the 6' side reads vehicles as they roll through, making it a fit for apartment complex entrances and farm or agricultural property gates.

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
