Starrett 52805 Feeler Stock Roll 0.008 in Tempered Steel

Product Description

The STARRETT 52805 is a tempered steel feeler stock roll used to measure and set precise gaps in mechanical assemblies. The roll is 0.008 inches thick and 0.5 inches wide, providing a consistent blade profile across its full 25-foot length. Technicians cut lengths to suit the application, making this format more cost-effective than individual feeler blades when repeated or custom-length gauging is needed. The tempered steel construction resists deformation under repeated use and maintains dimensional stability in shop environments. HVAC technicians, machinists, and field service pros keep this stock on hand for checking clearances, setting valve lash, and verifying component tolerances.

This feeler stock is suited for applications where standard pre-cut feeler gauges are too short or the required length varies by job. Common uses include checking heat exchanger burner-to-combustion surface clearances, verifying blower wheel-to-housing gaps, setting relay contact gaps, and general mechanical tolerance inspection. The 25-foot roll format supports light production environments as well as service trucks where flexibility matters. The 0.5-inch width fits most standard gap-check scenarios without modification.

Key Features

• 0.008-inch thickness provides a precise, consistent gauge dimension across the full roll
• Tempered steel construction maintains flatness and resists permanent bending under normal use
• 0.5-inch width accommodates a wide range of gap and clearance measurement tasks
• 25-foot roll length allows technicians to cut custom lengths as needed
• Single-roll packaging suits individual service use or low-volume shop stock

Compatibility

Designed as a general-purpose feeler stock roll for use wherever 0.008-inch gap gauging is required across HVAC, mechanical, and electrical service applications.

Installation Notes

Feeler stock is a measurement and setup tool, not a permanently installed component. Power down or de-energize any equipment before inserting feeler stock into gaps near moving parts or energized contacts. Use aviation snips or a sharp shear to cut clean, burr-free lengths from the roll. Dispose of cut scrap edges properly, as tempered steel edges can be sharp.
