Got a Reaaaaaly Heavy Work Bench that needs leveling?... Read On!Desunia is pleased to offer a leveler that's tough as nails, but as easy to install as it is to adjust.Real SteelHousings are made from 14 ga. (.080"), zinc plated steel. Each has a 7/16" wide ledger that hooks under the cabinet. This ensures the load gets carried directly on the leveler, not the screws. BTW the screws we provide are no joke. They're #10 Philips head (zinc plated) and penetrate a full 1" into the wood.Versatile Threaded LegThe legs have a 10mm dia. (a heavy 3/8") shaft that adjusts from 0" to 2-3/8". The feet are 1-1/4" dia. and spin freely on the threaded shaft. This allows them to tilt if your floor is really bad. Adjustments are easier too, as you won't be fighting the friction of the entire foot rubbing against the floor as it's being turned. Black polyethylene caps protect your floor and block any moisture from getting to the foot.Locknuts IncludedThese are a MUST for the workshop or garage, especially if vibrating equipment is involved. Just level the piece out and then snug the nuts up against the bottom of the housing. BTW, these are 10mm lock nuts, which would have been quite expensive if you had to provide them yourself.InstallationCould it be any easier? Just hook them onto the cabinet and attach with the provided screws. The whole thing could be done in 5 minutes (and that assumes you're taking it easy).AdjustmentIf you're able to reach below, it's easiest to just use a pry bar to lift the cabinet and turn the shaft with your fingers. If access is limited, use the provided 5mm hex wrench. An access hole can also be drilled in the cabinet floor to get the wrench through.Here's what you get...- 96 Heavy Duty Leg levelers w/locknuts- 384 Pan head screws (#10 x 1 1/8")- 5 mm Hex wrench
