National Loop Co. 24' (4' X 8') Direct Burial Vehicle Detection Loop with 100' Lead-In for 12' Wide Driveways - K-NL12-14-100

Placed before the paving crew arrives, the National Loop Co. 24' Direct Burial Vehicle Detection Loop with 100' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. Once a loop detector reads its signal, the loop covers the non-contact vehicle detection that UL 325 requires as one of the two means of entrapment protection for automated gates. Installation is a lay-and-pave job: set the loop on the graded sub-base, run the lead-in to the detector, and let the paving crew cover it. Its 8' 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 comfortable single-car driveways, newer suburban builds, and small business side lots.

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
