National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with 50' Lead-In for 11' Wide Driveways - X-NL11-14-50

Preformed and pave-ready, the National Loop Co. 22' Direct Burial Vehicle Detection Loop with 50' Lead-In is a 14 AWG inductive loop for direct burial under asphalt, concrete, or gravel. 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. Since the conduit protects the wire, the loop sits directly on the sub-base and gets buried under the new asphalt, concrete, or gravel surface. Its 7' 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 slightly wider suburban single-car drives and older neighborhoods with wider lot cuts.

Features:

• 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
• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
