But how big? Our handy stainless steel ruler with built-in drill gauge measures 6” in 0.1” increments and 15cm in 1mm increments, plus it has a set of (13) drill gauges from 1/16” to 1/4” in 1/64” increments.
From Helix®, this 18" long aluminum U.S. Standard triangular architects' ruler/scale has color-coded facings and is divided into 3. 1-1/2, 1, 3/4, 3/8, 3/16, 3/32, 1/2, 1/4 and 1/8 inch per foot. Yes, you can use it even if you're not an architect.
Banish plastic calipers. Replace them with these brushed stainless steel locking calipers. They measure spans up to 5" in 1/16" increments and 125mm in 1mm increments, and these are real beauties. Terry's buying a pair to use as a paperweight and have them on his desk, just in case calipers go the way of the slide rule and micrometer. Figures he owes it to his future grandkids to introduce them to these cool tools.
Electronics. The best thing that ever happened to calipers. Save your eyesight and measure accurate outside and inside dimensions with this digital instrument. Powered by an included button-cell battery, it measures up to 6 inches in .001 increments or 155 millimeters in .01 increments. Hardened stainless steel, 9-1/4" x 3" OA, with a locking vernier, it comes with a nice sturdy storage case and extra battery.
This 3-5/16” dia double-sided wire gauge wheel measures from 0-36 AWG on one face and from .005" to .325" on the other. It’s for non-ferrous metals, which is pretty much all of what you run across anyway, unless you’re Ferrous Bueller.
Sometimes, in a world of electronic measurement, you just feel like using a well tooled solid brass instrument--like this old-school vernier caliper. Has 4” x 1/16” and 100mm x 1mm scales that can be pulled apart to double as a depth gauge. Also very satisfying just to hold in your hand. Plus, it fits in your pocket!

You need something completely different, which is why we invite you to amp up your tape inventory with: (30) feet of 1-7/8” wide forest camouflage duct tape so no one can see what you fixed in the trees; or the extra-lovely (30) feet of black tape with red lipstick kiss marks to fix your ’80s rock gear; or (10) feet of 1-7/8” wide glow-in-the-dark medical tape so you can see what you fixed at night.
You get a nice, toolbox sized, teardrop-shaped chalk line box with a folding crank and 100 feet of cord. Box measures 5-3/8" x 7/8" x 1-1/8" thick. We'll pick one in red, orange or white. All you add is the chalk, available at your neighborhood hardware store.
