The Klein Tools 12 in. Canvas Tool Bag features a durable steel-frame mouth with a hinged closure for rugged use. Made of heavy-duty No. 8 natural canvas, this bag includes non-scratch studs on the base for added wear protection. Additionally, the bag's seams are reinforced with rivets to ensure durability. For a secure closure, two retaining straps with buckles are included. The bag's vinyl bottom and lower sides offer extra support and moisture resistance. For added convenience, this bag can be retrofitted with a shoulder strap kit (Cat. No. 5102S) which includes a leather strap with pad and snap hooks, rings, and fasteners for attaching rings to the bag.
