Inspired by an antique tool included in the famous H.O. Studley tool chest, this caliper is perfect for quickly checking dimensions. The direct-reading scale lets you measure objects or set the mouth opening without reference to a ruler.

It is marked for both inside and outside measurements up to 1 3/4", graduated in 16ths of an inch, and all markings are laser engraved for accuracy. A brass thumbscrew lets you lock the opening for comparative measurements, useful for checking for size when thicknessing boards with a hand plane or turning tenons on a lathe.

The gracefully curved legs are made from hardened and tempered stainless steel and the pivot is made of brass. Conveniently pocket sized at 3" long.
