Choosing total lock casters

Load: plan on three casters carrying a four-caster cart [S2]; at 350 lb each, a common rating here, that is about 1,050 lb, and the 350 lb top rating covers about 1,050 lb.
Mount: most total lock casters use a 2-3/8 x 3-5/8 in top plate; measure bolt hole centers on the old plate and compare.
Floor: on total lock casters, polyurethane and rubber are kinder to tile and finished floors; nylon, phenolic, polyolefin and semi-steel roll easier under heavy loads on smooth concrete.
Rig: swivel total lock casters are listed, with total lock brake options.
Heat: among total lock casters, the highest listed range is -45°F to 600°F on semi-steel; check the temperature field on each listing before oven or hot-room use.
