Model 139 JOBMASTER® Cabinet, 59.4 cu ft is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Superior. No compromise! Re: Model 109; Bombproof security, elegant simplicity, more rugged than any other solution available, and a fit and finish rivaling my Snap-On roll cab. The Knaack team has got their game on! If you're even considering a storage solution, set your hesitations aside and make the move with confidence. I cannot more highly recommend these products. There is no equal.

What is the load rating of the box and each shelf

storage box 139
Asked by: Bill
We have no published weight capacity for the Knaack boxes. We do, however, have a published weight capacity for the caster sets that are often used on the Knaack boxes. When casters are mounted to a Knaack box, the weight capacity of the casters is used as the limiting factor and therefore the weight capacity of the combination tool box and casters. Refer to the catalog for a listing of the weight capacities for the caster sets. When casters are not used on the boxes, "reasonable" care must be taken not to overload the product. The load capacity of the shelving is 200lbs per shelf.
