Abstract: An adjustable grizzly has a series of parallel bars which form a grate. Each bar of the grizzly is adjustable along the width of a frame. Pins on the underside of the bars drop into slots in the frame. The bars are slid into position along the frame and then locked into place by tension wedge locks. Matching spot faces on the bars with buttons on the frame further secure the bars into position and prevent lateral movement of the bars when the grizzly is in use.
