DeutschCan I retrofit the Leitertec system to my ladder?
This is possible for many ladder models. The ladder must meet the following criteria:
- The spar must be round
- If you remove the caps at the top, the inside diameter of the top spar must be 28 mm or 32 mm.
Attention: Sometimes there is a small number on the plastic part, this is usually the
outer
diameter of the spar. Don’t let this confuse you and measure instead. The inner diameter is usually 4 mm smaller than the outer diameter. - There must be an 8 mm spring-loaded button on the inside of the stile of the top step. Without the Leitertec system, this has no use (at the top level), which is why some manufacturers omit the push button.
This must protrude at least 5 mm for 28 mm uprights (inner diameter) and at least 7 mm for 32 mm uprights (see table).
| Inner diameter spar: a | 28 mm | 32 mm |
| Diameter push button: b | 8 mm | 8 mm |
| Push button length: c | >5 mm | >7 mm |
