Harbor Freight Locker Inset Deck Kit – Perfect Fit & Smooth Mobility Upgrade your Harbor Freight locker with this complete caster kit, featuring an 11 Gauge steel deck to mount casters and help support the weight of the locker and tools, With this kit you can also leave the lockers as a free standing unit. Designed for a seamless install, this kit mounts directly to the existing holes in your end cabinet, making setup quick and straightforward. You have 2 options for casters: Option A: We Include 5" casters that match perfectly with the height of Series 3 - 27” and 42” toolboxes, creating a clean, uniform workspace. You can also add the 2-1/2" spacer accessory in the drop down menu to raise our 5" caster to the same height as the 56" or 72" toolboxes. (You can get 5" all swivel casters or 2 Brakes and 2 Swivels) Option B: We match the drilling of the stock casters that go on the 56" Toolboxes and you purchase casters directly from Harbor Freight Parts online store. These casters are 2-1/2" taller than the 27" and 42" Casters. If you choose this option you don't need the steel spacers for the casters. https://www.harborfreight.com/parts In addition to cabinet mounting, this unit can also be used as a standalone rolling base, giving you added flexibility for your shop setup.
