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. Not sure how to use this gauge? Just strip a bit of wire and slide it through the gauge slots, not the holes, until you find the smallest one it'll fit through. It’s for non-ferrous metals, which is pretty much all of what you run across anyway, unless you’re Ferrous Bueller.

Working with curves? Of course you are. Or you will be someday. You need a gauge contour, and luckily for you, we just got a bunch of them. We’ll send you a pair of durable plastic JSK contour gauges, each with inch and centimeter measurements, and you’ll never again have to eye it or wing it by transferring a profile to a hunk of cardboard or piece of paper. In 10-inch and 5-inch sizes, these gauges are perfect for measuring pipes, circular frames, ducts and other curved objects when you’re fitting tile, carpet, molding or whatever. Also great for car body work, design and model-making of all kinds. This is the tool you didn’t know you needed until you had one. And we’ll send you (2) of them.

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.

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!

Whenever we drop in on our tailor for a fitting, he's got a tape measure hanging around his neck. So much more attractive than wearing a metal on his belt, we think. More useful too, when measuring humans. Now you can be a tailor too, with our tailor's tape measure in a soft fabric-like PVC material. Measures 60" (152cm) x 3/4", marked in 1/8" increments on one side and 1mm increments on the other, with metal tabs on each end. You'll get (3) in some combination of white, light blue and yellow.

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.

We’re especially high on this 5mW red laser level with a prism for perfect pictures, level studs or unslanted TV's. Measures 4" x 2-3/8" x 1-5/8" in a housing with dual bubble levers, pushpins and gum to mount it temporarily. If Bonanno Pisano had had one, that tower in Pisa might not lean at all, but, sadly, Alessandro Volta didn’t get around to inventing batteries for another 600 years. Speaking of which, you’ll need to add a pair of “AAA”s to make that red line happen.

We're in love with this little bugger. Slide this neodymium magnetic tip onto your 1" wide steel tape measure and it hangs on to steel surfaces by itself (attention electricians, plumbers & sheet metal workers) plus it has double top tabs so it will hook onto things above it, plus plus (here's the best part) it turns your tape into the longest pick-up tool on the planet.

This is the aluminum chalk-line reel familiar to carpenters everywhere. In the classic 4-3/4" x 3" diamond/teardrop shape with approx 100 feet of string and a folding crank to rewind it, but no chalk, which is available in good hardware stores everywhere, and most likely in the bad ones, too, come to think of it.

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.
