National Loop Co. 42' (6' X 15') Direct Burial Vehicle Detection Loop with 225' Lead-In for 21' Wide Driveways - E-NL21-18-225

Because it ships fully assembled in heavy-duty conduit, the National Loop Co. 42' Direct Burial Vehicle Detection Loop with 225' Lead-In is ready to lay down the moment the sub-base is graded. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 15' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to 2-car plus guest parking and wider rural/farm gate entrances.

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
