National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 225' Lead-In for 15' Wide Driveways - X-NL15-14-225

Made for new paving projects, the National Loop Co. 30' Direct Burial Vehicle Detection Loop with 225' Lead-In is a factory-wound 14 AWG loop that installs flat on the graded sub-base. 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 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:

• 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
