Starrett 52821 Feeler Stock Roll 0.024 in Tempered Steel

Product Description

The STARRETT 52821 is a tempered steel feeler stock roll used for precision gap measurement and clearance checks across a wide range of mechanical and HVAC service applications. At 0.024 inches thick and 0.5 inches wide, this roll provides a consistent, accurate gauge surface that can be cut to any working length as needed. The 20-foot roll format minimizes waste and allows technicians to tailor feeler strips to specific job requirements. Tempered steel construction delivers the rigidity and surface hardness needed for repeatable measurements under field conditions. Weighing 1 pound, the roll is compact enough for a standard tool kit.

Feeler stock in this gauge range is commonly used by HVAC technicians, machinists, and maintenance professionals when checking valve clearances, burner orifice gaps, bearing tolerances, and component alignment. The 0.024-inch thickness falls within a common working range for gas valve and heat exchanger inspection tasks. Residential and light commercial HVAC service, general mechanical maintenance, and industrial equipment alignment are all typical use scenarios for this product.

Compatibility

Designed as a general-purpose feeler stock roll suitable for use wherever 0.024-inch gauge tempered steel feeler material is required in mechanical, HVAC, or industrial maintenance applications.

Installation Notes

Feeler stock is cut to length using appropriate metal-cutting tools such as snips or a bench shear. Edges should be deburred after cutting to ensure accurate seating and prevent damage to mating surfaces. Power down or depressurize any equipment before inserting feeler stock into gaps or clearances on live machinery. Handle cut strips with care, as tempered steel edges can be sharp.
