The Mechanics Time Savers Lock-a-AirTool stores and locks air tools in an accessible holder. Dirt, grime and contaminates are reduced while tools are stored in the durable, impact- and chemical-resistant device. The Lock-a-AirTool fits on most service carts and toolboxes and can be operated with one hand. Users can slide the locking holders along the rail for necessary spacing, and individual holders can be added or removed to meet storage needs. The magnetic backing helps the Lock-a-AirTool stay in place.
