We have tbe grainger version at college. Full height, about $900?
Cabinets are not vidmar quality. Fit and finish good, but thinner and slides weaker. Here is the kicker. Opening them requires so much force to overcome catch it will give you carpal tunnels. If we had a safety nazi on staff when they found out they would send them back to avoid repetetive strain injury.
Made bones initially on telco gear when a rackmount might weigh a hundred Avoir, not 5 lbs or so. Early-on, we were trying to utilize rails with baked-on Molybdenum Disulphide in slickery polymer to avoid the spend on ball-bearings. Not HORRIBLE if the gear only needed pulled out once or twice a year, but still...
Nowadays, cheap Asian ball-bearing slides in-stock at Big Box, several lengths, all ya hafta doo is get ANAL about alignment, and you can double-up on both sides for some serious mass handling per-drawer. No metal-bending gear here, but I can chop-up plywood, metal channel, square tube, or extrusions well enough, so my "heavy" cabinets are DIY.
Cheap-shot?
The bottom drawer isn't even really a drawer. Platform, "parked" in a garage stall, rather. Serious-heavy rollers under, if not skates, damned HIGH upper-bound as to what it can hold.
Best of all? Pulling it out CANNOT "tip" the cabinet above it, even if it is still empty!
Try THAT with yer Listas and Vidmars!
We are folk as can "make anything", and yet we limit ourselves to store-bought storage that Lybarger's Corollary dictates will ALWAYS be at least slightly the wrong size?
80% of the time, surely good enough. Otherwise, JF build what you actually NEED. Not as if it had look good enough to go into the Royal Dining hall at some damned palace.
