Starrett 52817 Feeler Stock Roll 0.02in X 1/2in X 20ft Steel

Product Description

The STARRETT 52817 is a tempered steel feeler stock roll used for precision gap measurement and clearance checking in mechanical and trade applications. Measuring 0.02 inches thick and 0.5 inches wide with a 20-foot length, the roll provides enough material for multiple cuts and setups without frequent reordering. Tempered steel construction holds dimensional tolerances consistently across the full length of the roll. HVAC technicians, millwrights, machinists, and maintenance professionals use feeler stock to verify valve clearances, bearing fits, flange gaps, and alignment tolerances where a fixed-length blade gauge would be impractical. The roll format allows the installer to cut a custom-length piece to suit the job.

Feeler stock roll is well suited to residential and commercial service environments where technicians need flexible, field-cuttable gap stock. Common applications include checking burner orifice clearances, compressor valve plates, pump shaft alignments, and any mechanical assembly requiring precise gap verification. The 0.02-inch thickness is a commonly specified clearance dimension across a range of HVAC, refrigeration, and general mechanical equipment, making this roll a practical shop and service vehicle staple.

Key Features

• Tempered steel construction for consistent thickness and durability across the full roll length
• 0.02-inch thickness suits a wide range of standard mechanical and HVAC gap tolerances
• 0.5-inch width accommodates most standard feeler gauge applications
• 20-foot roll length allows field cutting to any required size
• Roll format reduces waste and adapts to irregular access spaces

Compatibility

Designed as a general-purpose feeler stock roll suitable for use in HVAC, refrigeration, mechanical maintenance, and light industrial applications where a 0.02-inch gap specification is required.

Installation Notes

Cut the feeler stock to the required length using metal shears or a sharp utility knife and straightedge before use. De-energize and lock out any equipment before inserting feeler stock into live clearance gaps on rotating or pressurized components. Handle cut edges with care, as tempered steel edges can be sharp. Dispose of trim stock safely to avoid jobsite injuries.
