Abstract: The disclosed invention provides for a lockable grass trimmer rack. The grass trimmer rack has inner frames and an outer frame. The outer frame slides vertically with respect to the inner frames to an open position or a closed position. The hooks on one side of the grass trimmer rack have slightly different inner diameters than the hooks on the opposite side of the grass trimmer rack to hold securely the larger diameter and small diameter ends of the grass trimmer. When the grass trimmer rack is in a closed position, the hooks clamp the grass trimmer in place and the equipment rack can be locked to prevent theft.
