Universal Jaws with Stop (VWSJ-5) — Caliper jaws with prism stop by Vertex

The Universal Jaws with Stop (VWSJ-5) are a precision clamping accessory designed to convert standard calipers into a repeatable measuring and holding solution for round and irregular workpieces in metalworking and engineering shops.

• Precision to 0.01 mm
• Prism stop for round stock
• Compatible with jaws 125–140 mm
• Robust 1.7 kg assembly

Reliable precision for routine measuring tasks

These jaws deliver measurable benefits where consistent readings matter. With a stated accuracy of 0.01 mm, the accessory reduces measurement variability and supports tighter process control on inspection benches and assembly stations. The specified accuracy refers to the repeatability achieved when the clamping surfaces are used with a compatible caliper; in practice, this translates to fewer rejects and less rework when comparing serial parts. The solid construction also minimises deflection during clamping, so the caliper jaws maintain alignment under typical workshop handling.

Secure handling of round and irregular stock

A defining feature is the integrated prism stop, engineered to centre and stabilise cylindrical components during measurement or light machining set-ups. The prism profile prevents lateral movement and allows a consistent datum when repeatedly checking diameters or concentric features. The accessory fits jaws with a width range of 125–140 mm, making it suitable for a wide range of vernier and digital calipers commonly used in production and toolrooms. By converting handheld equipment into a stable measuring fixture, the device shortens set-up time and improves operator confidence in routine checks.

Practical design for workshop integration

Compact dimensions of 175 x 39 x 49 mm and a net weight of 1.7 kg make the unit robust yet easy to handle and mount. The design follows familiar attachment principles so retrofitting takes minimal time and no specialist tooling. For shops focused on efficiency, the result is straightforward: quicker checks, consistent contact points and a lower risk of human error during repetitive measurement tasks. The accessory is particularly advantageous for small-batch producers and maintenance teams who require dependable measurement aids without investing in dedicated fixtures.

FAQ

What calipers are compatible with these jaws?
The Universal Jaws with Stop (VWSJ-5) are designed for use with caliper jaws that have a width between 125 and 140 mm; compatibility depends on the caliper's jaw mounting geometry and may require simple adjustment.

How does the prism stop improve measurements?
The prism stop centres round components and prevents lateral displacement, allowing repeatable contact points and more consistent diameter and concentricity checks when using the VWSJ-5 accessory.

Is the stated accuracy of 0.01 mm guaranteed for all setups?
The 0.01 mm figure describes the accessory's contribution to repeatability when used with a suitable caliper and correct technique; overall system accuracy will also depend on the measuring instrument and operator practice.

Can the jaws be used for light machining or only for measuring?
While primarily intended as a precision measuring aid, the robust construction and secure centring provided by the prism stop allow light holding tasks; heavy machining is not recommended.

Which manufacturer produces this accessory?
The accessory is supplied by Vertex and distributed under SKU VWSJ-5; Vertex production standards ensure consistent fit and finish for workshop use.
