National Loop Co. 56' (6' X 22') Saw Cut Vehicle Detection Loop with 225' Lead-In for 28' Wide Driveways - P-NL28-18-225

Contractors reach for the National Loop Co. 56' Saw Cut Vehicle Detection Loop with 225' Lead-In when an existing asphalt or concrete drive needs reliable vehicle detection. 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. Setup is a 3-step process: saw a 1/8" slot 1" deep in the pavement, press the loop in, and seal over it. With the 22' 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 apartment complex entrances and farm or agricultural property gates.

Features:

• 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 length of Polypropylene-insulated wire, leaving no splice point between the loop and lead-in to fail
• Predetermined number of machine-wound turns removes the guesswork of achieving optimal read range
• Neatly stacked turns accept loop sealant completely, locking out moisture for long service life
• Optimizes read range, eliminates faulty signals, and minimizes callbacks
• Saves labor cost compared with winding a loop by hand in the field
