National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 20' Lead-In for 21' Wide Driveways - E-NL21-18-20

Built for sites where saw-cutting is not an option, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 20' Lead-In is a preformed 18 AWG loop encased in liquid-tight conduit. 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. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. 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:

• 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
• One continuous, non-spliced wire runs through the loop turns and lead-in, eliminating splice failures
