National Loop Co. 92' (6' X 40') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 46' Wide Driveways - X-NL46-14

Contractors laying new asphalt, concrete, or gravel can set the National Loop Co. 92' Direct Burial Vehicle Detection Loop with Custom Length Lead-In directly on the sub-base and pave right over it. 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. 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 40' side crossing the lane and about 3' of clearance per edge, and the 6' side capturing vehicles in the direction of travel, the layout fits freight terminals, large agricultural processing plants, and wide estate boulevard gates.

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
