Length
Total ladder size
Total length with extensions
Total length of ladder in maximum extension.
(Maximum) standing height
This is the highest position of the standing ladder where you can safely stand.
Maximum reach
This is the highest position of the standing ladder plus 2 m (170 cm person with a vertical reach of 30 cm).
Clean internal width
The distance between the internal flanges of the side rails of the ladder.
Rail Width
Width of one rail.
Rail Depth
Depth of one rail. (Rounded to the nearest centimetre).
Depth of double partition
Depth of two overlapping partitions. (Rounded to the nearest centimetre).
Top width
Width at the top of the ladder.
Base width
Total width across the foot of the ladder. (Rounded to the nearest centimetre).
Base depth
Total depth across the foot of the ladder when extended. (Rounded to the nearest centimetre).
Maximum base distance
The maximum vertical distance from the highest rung or step the climber is recommended to use to the horizontal plane of the ladder base support, with the ladder in the preferred climbing position. (Rounded to the nearest centimetre).
Minimum Base Distance
Minimum vertical distance from the highest rung or step the climber is recommended to use to the horizontal plane of the ladder base support, with the ladder in the preferred climbing position. (Rounded to the nearest centimeter).
Maximum Working Height
Working height is the length of a non-self-supporting portable ladder measured along the rails from the base support point of the ladder to the point of placement at the top.
Minimum Working Height
Working Height is the length of the non-self-supporting portable ladder measured along the rails from the base support point of the ladder to the top storage point.
Storage Height
Measured from the bottom of the foot to the highest point of the ladder with the storage position closed. Extendable legs are positioned vertically. (Rounded to the nearest centimetre).
Stacking width with base
Measured across the overall width of the widest point of the ladder.
Folding Depth
Measured across the deepest depth from front to back with the ladder closed in the storage position, including any legs or wheels.
