Tub Cover
An operational characteristic of all grinders is that objects may be thrown out of the tub. Tub Covers reduce the risk of potential injury or property damage from thrown objects. Proper use of the Tub Cover provides the operator with a means to help control the area over which thrown objects may fall. Combined with a decrease in the percentage of objects thrown from the tub, the Tub Cover is an effective means of reducing risk to personnel and property.
