Spi 91-453-1 Feeler Stock Roll 0.04 in 0.5 in Wide 25 Ft

Product Description

The SPI 91-453-1 is a high carbon steel feeler stock roll used for precision gap measurement and clearance checking in mechanical and industrial applications. At 0.04 inches thick and 0.5 inches wide, this roll provides a continuous 25-foot length of flat gauge stock that can be cut to length as needed. High carbon steel construction delivers the stiffness and durability required for accurate feeler work in engines, HVAC equipment, compressors, and other close-tolerance assemblies. Technicians use feeler stock rolls where pre-cut feeler gauges are too short or too rigid for the job at hand.

This feeler stock roll is suited for residential and commercial maintenance tasks where gap clearance must be verified or set. Common applications include checking valve clearances, bearing fits, gasket compressions, and alignment tolerances in mechanical systems. The roll format allows the user to cut custom lengths for tight or awkward access points. It is a practical bench and field tool for HVAC technicians, millwrights, machinists, and general maintenance professionals working with precision equipment.

Installation Notes

Cut feeler stock to the required length using metal shears or a utility knife with a straightedge before use. Always de-energize and lock out equipment before inserting feeler stock into any clearance gap on powered machinery. Handle cut edges carefully as high carbon steel can produce sharp burrs. Follow equipment manufacturer specifications for allowable clearance tolerances when using feeler stock for adjustment or verification.
