Review on 🔧 Set of 8 Combo Caster Swivel Plate 5 Inch with Brake & 4 Plate Heavy Duty Wheels on Blue PU, Including Heavy Duty Screws by Michael Adams

It's rare to find a better deal than our old pal Harbor Freight. These are cheaper and better. I put four in the bottom of a wheeled seedling box that probably weighs about half a ton. A wheel broke; I should have followed my intuition and used a little longer. It is recommended to leave about 3/4" of space between the screw holes and the edge of the material and install on plywood that is 3/4" thick or deeper. The wheel that came out hit the 2x4 too close to the edge. It salts along the fibers. Screws torqued 1 1/2 inches into plywood were better able to withstand shear forces generated by driving over a bump or pebble.
