Choosing rigid casters

Load: plan on three casters carrying a four-caster cart [S2]; at 440 lb each, a common rating here, that is about 1,320 lb, and the 770 lb top rating covers about 2,310 lb.
Mount: most rigid casters use a 3-3/4 x 4 in top plate; 2 x 3 in and 2-1/2 x 3-5/8 in plates are listed too; measure bolt hole centers on the old plate and compare.
Floor: on rigid casters, rubber and polyurethane are kinder to tile and finished floors; nylon and stainless steel roll easier under heavy loads on smooth concrete.
Rig: rigid rigid casters are listed.
