National Loop Co. 28' (4' X 10') Saw Cut Vehicle Detection Loop with 20' Lead-In for 14' Wide Driveways - X-NL14-18-20

Because it arrives prewound and precut, the National Loop Co. 28' Saw Cut Vehicle Detection Loop with 20' Lead-In takes the guesswork out of adding vehicle detection to an existing driveway. Paired with a compatible loop detector, it senses the metal mass of a passing car or truck and signals the gate operator to open, hold, or reverse, providing one of the two means of entrapment protection UL 325 requires for automated gates. Installation calls for sawing a 3/16" slot 1" deep into existing asphalt or concrete, laying the loop in the slot, and sealing it, with no hand-winding or turn counting required. Its 10' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to wide single-car or tight 2-car driveways and long rural drives.

Features:

• Optimizes read range, eliminates faulty signals, and minimizes callbacks
• 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 Polypropylene-insulated wire runs through the loop turns and lead-in, eliminating splice failures
• Factory-set turn count means optimal read range without any on-site adjustment
• Precisely stacked wires let loop sealant fully encapsulate the loop for lasting weather protection
