Compare telescoping ladder class ceilings against LadderReach estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Clears when | Typical fit | Trade-off |
|---|---|---|---|
| 13 ft telescoping | support + 3 ≤ 13 ft | Lower landings / first-story eaves within budget | Too short once needed clears 13 ft |
| 17 ft telescoping | support + 3 ≤ 17 ft | Mid heights that clear 13 ft but stay within 17 | Still short of taller access jobs |
| 20.5 ft telescoping | support + 3 ≤ 20.5 ft | Taller portable access on this ladder | Largest class here; verify live max length |
| NO_MATCH (above ladder) | support + 3 > 20.5 ft | Need beyond this site’s ceiling | Do not force 20.5 ft — size up outside this screen |
