No they are punch formed in the metal bottom. There are little rubber inserts that would take maybe 1/8 of an inch off...but that would not be able to make enough difference. :O
Right after JDrifter said that he was going to buy it today I said...hmmm I better pull my spare out of the gig box and see how tall it was. It's been about a year since I have had that rack system back in my shop so I decided to give my KJ a call and he confirmed it occupies 1-1/2 of the top 2 spaces on my 10 space rack.
I'm glad I called!!
