Never Fail Loop Systems, Inc. USA
is the premier manufacturer for preformed inductive loops for all transportation modes. Our loops are manufactured in Milwaukie, OR, and are installed across the globe. Made in USA.
We take great pride in manufacturing NO-SPLICE loops, and only use the most durable materials available. Our loop builders are talented and experienced, and special requests are never an issue. We are committed to manufacturing the best preformed inductive loops for our customers.
- ASPHALT/CONCRETE OVERLAY
- ALL APPLICATIONS/CUT-IN
- SPECIAL
ASPHALT/CONCRETE OVERLAY
Model A series Detectors are designed for asphalt overlay, and concrete overlay with or without rebar.
Model A series loop heads are constructed from rigid polypropylene conduit, and feature expansion/contraction joints. O.D. is 16MM (5/8")
ASPHALT/CONCRETE OVERLAY
Model F series Detectors are designed for asphalt overlay, concrete overlay, and cut-in.
Model F series loops are constructed from abrasion resistant polyurethane, with great flexibility over a wide temperature range. O.D. is 9.5MM (3/8")
ALL APPLICATIONS/CUT-IN
Model C series Detectors are designed for asphalt overlay, concrete overlay, cut-in, or as an above ground “stick-on” loop detector.
Model C series loops are constructed from highly abrasion resistant nylon alloy cover. O.D. is 16MM (5/8")
SPECIAL
Never-Fail Loop designs custom pre-formed loops for all shapes, sizes, and specifications, and for all traffic modes.
We specialize in Quadrupoles, Light Rail Transit (LRT), and Bicycle/Motorcycle detection, and “Doubles” (two loops sharing a single tail).
