Key Ring Ruler - Measuring Rod For Keychain - Inchworm The Inchworm key ring is the perfect on-the-go ruler accessory. It is a functional "ruler in the round," with a diameter of 3/16 of an inch, and grooves cut in ? inch increments up to 3 inches. The outside of the ruler is bead blasted to a matte finish, with new grooves that are then cut into the exterior at the ½ inch and 1 inch marks for ease of reading. The Inchworm will come in handy in a variety of practical ways, for example: checking the width of a broken fan belt or hose for replacement, checking screw lengths, comparing different product sizes at the store, and comparing the physical size of a part with the product packaging specifications at the store. Whatever you need to measure, the Inchworm is the best instrument to get the job done.
