National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 100' Lead-In for 15' Wide Driveways - K-NL15-14-100

Placed before the paving crew arrives, the National Loop Co. 30' Direct Burial Vehicle Detection Loop with 100' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. Its 11' 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 standard 2-car driveways on modest suburban lots.

Features:

• 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
• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
