Beautifully engineered from two pieces of aircraft-grade aluminum, this clamp features a GRS-style dovetail mounting plate that lets you position a bench pin or any GRS system tool anywhere in your workshop. Compact and fully portable, it travels easily to shows or off-site work, and adjusts to fit table thicknesses ranging from \u003cstrong\u003e3\/4\" (19mm)\u003c\/strong\u003e — a lightweight card table — up to \u003cstrong\u003e3-5\/8\" (94mm)\u003c\/strong\u003e on a heavy woodworker's bench.\u003c\/p\u003e\n\u003cp\u003eKnew Concepts engineered serious flexibility into the two-piece clamping system. The black aluminum angle base reassembles in four different positions, with two length settings on each leg and a range of offset holes that overlap intentionally — so you can always position the clamping screw to clear support rails, lips, or other obstructions under your work surface. There is always something in the way, and this clamp gives you the options to work around it.\u003c\/p\u003e\n\u003cp\u003eThis is the \u003cstrong\u003eAnvil Type\u003c\/strong\u003e (part number 149.666ANVIL), distinguished by a \u003cstrong\u003esteel insert for hammering\u003c\/strong\u003e and a \u003cstrong\u003edual-scale ruler\u003c\/strong\u003e (metric and inch) on the upper plate. The upper plate is Mil-spec Class 3 hard-anodized aluminum — as hard as aluminum gets — so an accidental file slip won't transfer contamination to your work. It's not a dedicated anvil, but it's built to resist the demands of real bench work.
