Outside Spring Calipers

Outside Spring Calipers for measuring the outside diameter or wooden spindles or metal pipes.

Available in the following sizes:

• 100mm (4in).
• 150mm (6in).
• 200mm (8in).

The polished, natural steel finish legs are carefully balanced and made of flat stock, with treated points. A strong but flexible bow spring and centrally located adjustment screw give a smooth and precise action.

Once adjusted the tension of the spring keeps the Caliper at the same setting for quick and easy measurement comparisons.

If you also need to measure the diameter of a pipe or hollow spindle then take a look at the Inside Spring Calipers.
