National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with 20' Lead-In for 11' Wide Driveways - E-NL11-18-20

For driveways getting a fresh surface, the National Loop Co. 22' Direct Burial Vehicle Detection Loop with 20' Lead-In provides vehicle detection without cutting into the finished pavement. 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 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:

• 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
• Factory-set turn count means optimal read range without any on-site adjustment
