Cart Armour is an interlocking steel paneling system that closes off your utility cart, securing its contents from theft. Featuring 16-gauge steel panels that you can install in 15 minutes or less, Cart Armor is the perfect option for those looking to upgrade their tool cart. The design allows both installation on a new rolling tool cart or retro-fitting an existing tool box cart without having to modify the cart in any way. The recessed padlock design accommodates a variety of padlocks while preventing the lock from snagging on doorways, materials, or clothing. Run power to the interior of the mobile tool cart with a grommeted electrical pass-through, which keeps the cord free from damage. This Cart Armor model fits Rubbermaid cart model 4520-88. A tan, powder-coat finish ensures maximum protection against chipping and scratching. CART NOT INCLUDED.
