## Summary description

Proline Tools 21210 is a single-pack feeler gauge designed for measuring narrow gaps and clearances. The tool consists of multiple thin metal blades of varying thicknesses (feeler blades) mounted together for sequential gap checking, adjustment and inspection tasks. Suitable for automotive, mechanical maintenance and precision assembly work where accurate gap measurement is required.

## Long description

Proline 21210 is a single-pack feeler gauge consisting of a set of individual stainless steel blades of varying thicknesses mounted on a pivot. Designed for precise measurement of narrow gaps and clearances, this metal blade set is intended for sequential checking, adjustment and inspection tasks where repeatable thickness reference is required. The compact, foldable design enables easy storage and transport while protecting the blades when not in use.
Advantages
The stainless steel blades deliver stable, wear-resistant thicknesses for reliable gap measurement over repeated use. The pivot-mounted arrangement keeps blades aligned and allows quick selection of the required thickness. The compact single-pack format is convenient for workshop toolkits and mobile maintenance work. The simple, robust construction requires no calibration and is compatible with standard mechanical and automotive service procedures.
Suitable for
 Measuring valve clearances and spark plug gaps in automotive maintenance
 Checking bearing and shaft clearances in mechanical repair
 Alignment and fit-up tasks in precision assembly
 General gap verification in workshop and field service
Key specifications
 Material: stainless steel blades
 Form: multiple thin blades mounted on a pivot for sequential use
 Packaging: single pack with foldable blade holder
 Application area: gap and clearance measurement for mechanical and automotive tasks
How to use
Select the blade corresponding to the target thickness and unfold it from the holder. Slide the blade into the gap to be measured; a slight friction fit indicates a match between blade thickness and clearance. If the blade is too loose or too tight, fold it back and try the next thicker or thinner blade until the correct feel is obtained. After use, fold blades back into the holder to protect edges and store the tool in a toolbox or tool pouch.
Usage recommendations
Use the feeler gauge on clean, dry surfaces and ensure mating parts are free of debris or burrs for accurate readings. Avoid bending blades beyond their elastic limit; if a blade is deformed, replace the set to maintain measurement accuracy. For repeated automotive or precision work, periodically inspect blades for wear and corrosion and keep them lightly oiled during storage if exposed to humid conditions.
