National Loop Co. 18' (3' X 6') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 9' Wide Driveways - K-NL09-14

Built for sites where saw-cutting is not an option, the National Loop Co. 18' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a preformed 14 AWG loop encased in liquid-tight conduit. Once a loop detector reads its signal, the loop covers the non-contact vehicle detection that UL 325 requires as one of the two means of entrapment protection for automated gates. 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. With the 6' side crossing the lane and about 1' 6" of clearance per edge, and the 3' side capturing vehicles in the direction of travel, the layout fits suburban single-car driveways, condo/townhome parking pads, and small ranch homes.

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
