Value Collection ID/4 Inside Caliper 4 Inch Spring Joint

Product Description

The VALUE COLLECTION ID/4 is a spring-joint inside caliper designed for precision inside-diameter measurement in trade and industrial applications. Built with a flat steel leg and a polished finish, this caliper measures up to 4 inches (100 mm) maximum. The spring-joint mechanism keeps consistent tension on the legs, and the quick-nut adjustment allows fast, repeatable setting without losing your measurement. At 0.12 pounds, it is a compact, lightweight hand tool suited for machinists, pipefitters, and maintenance technicians who need reliable inside-dimension transfer work.

This inside caliper is used wherever a technician needs to measure bore diameters, inside pipe dimensions, or other internal clearances. It is appropriate for both shop and field use in plumbing, mechanical, and general maintenance environments. The flat leg profile reaches into tight bores cleanly, and the polished steel finish resists light corrosion during normal handling. Typical applications include checking pipe bore ID, fitting clearances, and verifying machined inside dimensions during fabrication or repair work.

Key Features

• Spring-joint design maintains consistent leg tension for stable measurements
• Quick-nut adjustment for fast, precise leg setting
• Flat leg profile for access to tight inside diameters
• Measures up to 4 inches (100 mm) maximum inside diameter
• Polished steel construction for durability and corrosion resistance

Compatibility

Designed as a general-purpose inside caliper suitable for standard measurement and layout tasks in machining, plumbing, and mechanical maintenance applications.

Installation Notes

Inside calipers are hand tools that require no installation. Set the leg spread to the desired measurement using the quick-nut adjustment before transferring to a rule or micrometer for reading. Handle with care to preserve leg tip geometry, as bent or worn tips reduce measurement accuracy. Store in a dry location to protect the polished steel finish from corrosion.
