National Loop Co. 28' (4' X 10') Direct Burial Vehicle Detection Loop with 125' Lead-In for 14' Wide Driveways - X-NL14-14-125

Designed to be paved over, the National Loop Co. 28' Direct Burial Vehicle Detection Loop with 125' Lead-In is a preformed 14 AWG inductive loop for new-surface installations. 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. With the 10' 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 wide single-car or tight 2-car driveways and long rural drives.

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
