How wide is your wheeled tool cabinet, chest, roll-away or whatever you want to call it? I have my eyes on a 40" wide craftsmen professional w/ ball bearings for 899 for the bottom, and 599 for the top. (canadian prices) Would this be wide enough? or should I look for one bigger???? here is the link to sears.ca for the set http://www6.sears.ca/webapp/wcs/sto...yId=10412&langId=-1&rrc=1&productId=158302984 opinions?
