As the old woodworker’s adage goes, if you want error-free results, measure twice, cut once. Rockler helps you measure right with the handiest, most precise marking and measuring tools around. For everyday use, choose from a variety of tape measures, including center-finding tapes and flat-back tapes for measuring curved objects. For more precise measurements and machine setups, try a digital caliper or dial caliper with either fractional or decimal readings. Or check out our precision steel rules and hook rulers from top names like Starrett and other competing brands. Rockler also offers a variety of Starrett angle protractors and angle gauges/angle finders for dialing in your miter saw for trim work. For turners, a spindle gauge, thickness gauge and caliper set are indispensable tools.

And don’t forget about marking tools. Even the humble carpenter’s pencil earns a place in our offerings (its flat profile won’t roll off the bench). Rockler offers traditional cabinetmaker’s rosewood marking gauges, mortise gauges, miter gauges and the more modern “wheel” marking gauges. If you prefer the convenience and eraseability of a pencil line, try Incra’s Precision T-Rules with a dedicated slot for every 1/64” increment! We also offer compasses, trammel points, precision scribing tools, and of course, the standard try-square and combination square.

Measuring and marking are the last things you do before cutting, and if you can get that right, the cutting is the easy part. You can get it right with the right tools from Rockler - helping you create with confidence for over 50 years.

"I live in NJ, and wish there was a physical store near where I live. My experience with rockler.com is second to none. Not only are your products first rate, but customer service/product support is exceptional. I've called several times, and never received someone on the other end of the phone who was anything but extremely helpful, patient, and friendly. The biggest compliment I can give is that I TRUST Rockler for all my woodworking needs. The only other store I can say that about is LL Bean. My wood working friends in western NJ love Rockler. Keep on keepin' on - and get a store here in Jersey!!"
