Grizzly® Specifications


The Grizzly® Trackout Control Device consists of 8 ft. by 10ft. or 8 ft. by 20 ft. sections of steel positioned at alternating elevations and consistently spaced to appropriately shake vehicles. The device is typically setup with three sections abutted tightly together to form a continuous track (3 grates form a continuous track or shaker 24-foot long). By abutting each of the 8 foot sections end to end, a single “shaker” 24 feet of effectiveness.   The Grizzly® can also be abutted  side by side, therefore allowing for unlimited length and width for the Rumble Grate.®
