Slotted “SPEED” channels in a variety of lengths offer a stable landing for roof and floor truss jigging. These channels also create multiple angles, allow the user to change configurations, and can be removed quickly and easily. However, their design lends them the ability to be removed without completely removing the bolt or table hardware. With one open end, simply loosen, and away you go. Replace it with a longer or shorter “speed” channel, and the next truss design is quickly under way. All parts are American steel machined and welded right here in the United States. Designed at 1-5/16” tall, these slotted “speed” channels will not interfere with your nit or finish roller.
