National Loop P-NL12-18-50 Preformed Saw Cut Loop
The National Loop P-NL12-18-50 is a 4′ x 8′ preformed inductive saw cut loop featuring 18GA wiring and a non-spliced, machine-twisted polypropylene-wrapped copper lead-in — engineered for reliable vehicle detection.
Overview
The National Loop P-NL12-18-50 is a 4′ x 8′ preformed inductive saw cut loop with 18GA PNL wiring in white. Built from a single continuous wire throughout both the loop turns and lead-in, this loop is designed to fit precisely in a 1" deep saw cut. The non-spliced, machine-twisted lead-in uses polypropylene-wrapped copper wire, and the precisely stacked wire configuration allows sealant to fully encapsulate the loop — an advantage over hand-wound alternatives.
Key Features
- One continuous wire throughout loop turns and lead-in — no splices
- Machine-twisted, polypropylene-wrapped copper lead-in wire
- Designed to fit perfectly in a 1" deep saw cut
- Precisely stacked wires allow sealant to fully encapsulate the loop
- Reduces guesswork for determining number of turns for optimal read-height
- Optimizes read-height, eliminates faulty signals, and minimizes callbacks
- Faster installation compared to hand-wound loops
