National Loop Co. 20' (4' X 6') Direct Burial Vehicle Detection Loop with 75' Lead-In for 10' Wide Driveways - E-NL10-18-75

Contractors laying new asphalt, concrete, or gravel can set the National Loop Co. 20' Direct Burial Vehicle Detection Loop with 75' Lead-In directly on the sub-base and pave right over it. 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. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. With the 6' side crossing the lane and about 2' of clearance per edge, and the 4' side capturing vehicles in the direction of travel, the layout fits standard single-car suburban homes, duplex driveways, and small farm entrances.

Features:

• 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
• 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
