ProGrip Straight Edge Clamps Ideal for Cutting Large Sheets of Plywood and Dado Slots (All 3 Clamps 24, 36 and 50 inch)
ProGrip Straight Edge Clamps Ideal for Cutting Large Sheets of Plywood and Dado Slots (All 3 Clamps 24, 36 and 50 inch)
  • No more c-clamps when trying to secure a straight edge to your large or small wooden panels! Cut large panels, small panels, rout straight dado’s and more! ProGrip Straight Edge Guides are not only great straight edge guides, they are super easy to align and even easier to clamp into place. Made from extruded aluminum and with the extra wide 2-3/16 inch tube rail, the ProGrip Straight Edge Guide Clamps are robust guides that are made for everyday workshop or contractor use.
  • Cut straight, true lines with circular saws, routers, trim routers, jig saws and many other power tools you probably own. These clamps are ideal for cutting large sheets of plywood in half (with a 50” straight edge guide). Each clamp is identified by the maximum clamping distance between jaws. Another great application for these clamps is cutting dado slots for bookshelves. The alignment and cutting process for dados is so much easier than ever before with the ProGrip Straight Edge Guides.
  • Each clamp rail is manufactured with a low profile to make guiding your power tool along the edge much easier. The low profile has also been designed with guide accessories in mind. The clamp rails accept many different accessories (sold separately) or can create your very own jigs and fixtures to use with the ProGrip Straight Edge Guides. Each ProGrip Straight Edge Guide has the exact same profile regardless of length.
  • How does it work? Each ProGrip Straight Edge Guide Clamp has one adjustable jaw and one fixed jaw. The fixed jaw typically will go against the edge of the board closest to you. Once you place the clamp on your board with the fixed jaw over the end, the adjustable end gets drawn in against the opposite side of the board. Once set and aligned, you secure the clamp by simply locking it down with the 3 position lock lever.
  • The lock lever on each clamp can be secured into one of three positions, each position provides varying amounts of pressure. Depending on your project or application, you may need to apply more pressure by securing the lock lever to the appropriate position. Once secured, the ProGrip Straight Edge Guide Clamp is designed to have zero side to side play with minimal deflection to provide you with the ideal straight edge to make clean, smooth cuts every time!
