This tool comes in handy when scouting lumberyards or trolling in the offcut bin. Acting as a simple go/no-go gauge for checking lumber thickness, it has steps that measure thickness from 3/8" to 2" (in 1/8" increments under 1" and 1/4" increments over 1").
It is especially useful when you are looking for a piece with a certain minimum thickness. Based on common lumberyard promotional giveaways from the 1950s, it has a sleek, thin design that slips easily into a pocket or attaches to a key ring.
Made in Canada from stainless steel, it is about 3 1/4" long overall and comes with a split ring.
