National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with 75' Lead-In for 11' Wide Driveways - E-NL11-18-75

Built for sites where saw-cutting is not an option, the National Loop Co. 22' Direct Burial Vehicle Detection Loop with 75' Lead-In is a preformed 18 AWG loop encased in liquid-tight conduit. 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. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. With the 7' side crossing the lane and about 2' of clearance per edge, and the 4' side capturing vehicles in the direction of travel, the layout fits slightly wider suburban single-car drives and older neighborhoods with wider lot cuts.

Features:

• 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
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
