National Loop Co. 50' (6' X 19') Direct Burial Vehicle Detection Loop with 100' Lead-In for 25' Wide Driveways - E-NL25-18-100

Contractors laying new asphalt, concrete, or gravel can set the National Loop Co. 50' Direct Burial Vehicle Detection Loop with 100' Lead-In directly on the sub-base and pave right over it. Working through a compatible loop detector, it detects the metal mass of vehicles overhead, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. 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. Formed as a 6' x 19' rectangle, it centers in the lane with about 3' of clearance per edge, a proportion that suits estate properties, horse farms, and private road entrances.

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
