Compare garage shelving class ceilings against ShelfLb estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Clears when | Typical fit | Trade-off |
|---|---|---|---|
| 400 lb/shelf / 2,000 total | shelf_lb ≤ 400 | Light-to-moderate garage bins and parts | Too light once a shelf clears 400 lb |
| 500 lb/shelf / 2,500 total | shelf_lb ≤ 500 | Heavier tools/boxes that clear 400 but stay within 500 | Still short of 600 lb single-shelf loads |
| 600 lb/shelf / 3,000 total | shelf_lb ≤ 600 | Heaviest portable class on this ladder | Largest class here; verify live ratings |
| NO_MATCH (above ladder) | shelf_lb > 600 | Load beyond this site’s ceiling | Do not force 600 lb/shelf - size up outside this screen |
