Compare plate caster class ceilings against CasterLb estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Clears when | Typical fit | Trade-off |
|---|---|---|---|
| 350 lb/caster (4 in) | total_lb / 4 <= 350 | Light carts and benches under about 1400 lb total | Too light once the per-caster share clears 350 |
| 450 lb/caster (5 in) | total_lb / 4 <= 450 | Heavier benches that clear 350 but stay within 450 | Still short of 700 lb per-caster loads |
| 700 lb/caster (6 in) | total_lb / 4 <= 700 | Heaviest portable class on this ladder | Largest class here; verify live ratings |
| NO_MATCH (above ladder) | total_lb / 4 > 700 | Load beyond this site ceiling | Do not force 700 lb/caster - size up outside this screen |
