Model 99 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.

why is the 99 heavier than the 139?

The question was answered that the only difference between the two is the weight, and that is a very unsatisfying answer, is it a heavier Ga. material? The product description of the 139 says it is made of 16 gauge but the 99 does not specify.
Asked by: Ken
The model 99 has 4 doors so it will open from both sides. The 139 only has 2 doors and will only open from the front
