Custom-Made Precision

Every order for Patriot Detection, LLC preformed inductive loops (P-ILDs) is meticulously custom-made and assembled in our factory, ensuring complete customer satisfaction. This personalized assembly process eliminates costly mistakes and allows for total quality control over materials and methods by our dedicated staff and management. The wire used in our preformed loops is machine-turned and safeguarded by a high-pressure, high-temperature conduit filled with water-blocking material.

Superior Performance

Patriot Detection, LLC P-ILDs are guaranteed to significantly reduce or eliminate numerous issues, including frequent lane closures for re-cutting conventional loops, pavement deterioration from repeated cutting, red light violations due to driver frustration with timed intersections, excessive exhaust pollution from long red light waits, and costly motorist call-in's. Additionally, our loops help avoid the need for expensive equipment required by conventional loop failures, ensuring more efficient and reliable traffic management.

Cost-Effective Solutions

Patriot Detection, LLC preformed inductive loops (P-ILDs) and delivered significant cost savings for both new constructions and existing loop cut-ins. These loops are a superior, economical alternative to standard electrical wire and are rated for direct hot asphalt pave-over and concrete overlay, compensating for reinforcing steel draw. For cut-in installations, they eliminate the need for “45-ing” corners or using a backer rod. Unlike other traffic detection technologies, our in-ground and non-intrusive loops offer an efficient solution.
