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

Placed before the paving crew arrives, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with Custom Length 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. Installation is a lay-and-pave job: set the loop on the graded sub-base, run the lead-in to the detector, and let the paving crew cover it. The 15' 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 2-car plus guest parking and wider rural/farm gate entrances.

Features:

• 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
• One continuous, non-spliced wire runs through the loop turns and lead-in, eliminating splice failures
• Liquid-tight conduit stands between the wire and sharp stones, chemicals, ground movement, and harsh weather
