If you like dimensioning large sheet goods with a handheld circular saw, you'll love the Kreg Rip-Cut Saw Guide. There's no need to juggle guide rails, a pencil or tape measure. In fact, there's no measuring or marking required—just slide the fence on the Rip-Cut to any setting from 1/8'' to 24'' and rip a clean, straight line right down the length of the sheet. The Rip-Cut attaches easily to virtually any circular saw, whether left- or right-handed. Adjusting the fence is easy, simply open the cam lever, and slide it to your setting, just like a table saw fence.
