National Loop Co. 18' (3' X 6') Direct Burial Vehicle Detection Loop with 100' Lead-In for 9' Wide Driveways - X-NL09-14-100

Made for new paving projects, the National Loop Co. 18' Direct Burial Vehicle Detection Loop with 100' Lead-In is a factory-wound 14 AWG loop that installs flat on the graded sub-base. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. 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:

• 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
• Factory-set turn count means optimal read range without any on-site adjustment
• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
