National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 250' Lead-In for 15' Wide Driveways - X-NL15-14-250

Skip the slot cutting entirely: the National Loop Co. 30' Direct Burial Vehicle Detection Loop with 250' Lead-In lays on the sub-base and gets paved over with the new surface. 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. The pave-over design means no slot cutting: the loop goes down on the graded base and the fresh surface finishes the installation. Its 11' 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 standard 2-car driveways on modest suburban lots.

Features:

• 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
• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
