National Loop Co. 56' (6' X 22') Saw Cut Vehicle Detection Loop with 30' Lead-In for 28' Wide Driveways - P-NL28-18-30

Installing the National Loop Co. 56' Saw Cut Vehicle Detection Loop with 30' Lead-In means sawing one slot, laying in a preformed 18 AWG loop, and sealing 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. Fitting takes one shallow saw cut: a 1/8" slot, 1" deep, cleaned out, filled with the loop, and sealed with loop sealant. 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:

• 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 Polypropylene-insulated wire runs through the loop turns and lead-in, eliminating splice failures
• Factory-set turn count means optimal read range without any on-site adjustment
• Precisely stacked wires let loop sealant fully encapsulate the loop for lasting weather protection
• Cuts down on faulty detection calls and repeat service trips thanks to consistent machine winding
