Rockwell Rk9000 Jawhorse This accessory may not look like much

This accessory may not look like much, but what it gives you is another 14 inches of clamping in the throat, and the ability to make some outriggers for the Rockwell RK9000 Jawhorse to support really big stuff like a 4x8 sheet of plywood. Plus along with the bigger throat clamp, are two support gizmo clamps that you can use 2x2 or 2x4 as extension legs for the support.

Rockwell recommends that you make your outriggers out of wood, so that if you misjudge your cut with your saw, that you don't hurt yourself or the blade. (cutting into the Jawhorse itself would also not be good. But it's easier to see where the Jawhorse is than a wide underneath support beam.)

The new throat has 4 sets of screw holes, two at each end. For mid sized stuff, you can screw the support wood right through the throat. For really big pieces, just screw the back piece, and let the front one float on the extension legs. If you use a 10ft 2x4 it will sit flat, provided your extension legs aren't pushing it up.

14 inches may not sound like much either but it's the difference between clamping a piece of 4x8 plywood or going back to a sawhorse setup. And you bought the Jawhorse to have something better. So if you handle/cut the big stuff, even occasionally, it's worth it. Also the side leg support clamps can be used to support a 2x4 for a do-it-yourself miter box table. And has been mentioned, it doesn't take up much room in your shop for the rest of the time.
