The Kreg Jig K5 incorporates the best features of every Kreg Jig that came before with upgrades you"ve never seen. That starts with an all-new clamping mechanism that you can adjust without tools or adjusting nuts to match your work piece thickness. Just slide the clamp into place, "click" the large front-mounted clamp handle, and your jig is set to hold your work piece tight every time. Plus, you"ll find large support wings to hold your work piece steady-and they have storage compartments inside. Add in a batch of other great features like a standard swiveling dust-collection port, spring-loaded stop for the Drill Guide Block, and, of course, the ability to remove the Guide Block for portable use, and you have, quite simply, the most advanced Kreg Jig yet.
