Glossary

 

Below are terms and definitions used to describe our ladder designs and characteristics:

Stile - Lateral part of a ladder which supports the rungs or steps as well as cross struts of supporting legs. Also known as the "body" of the ladder.

Rung/Step - Climbing support with a standing surface which interconnects two stiles.

Platform - Topmost standing surface of a standing step ladder which is different from a step.

Hinge-joint - Device on standing ladder which secures the two legs of the ladder. Check out our innovative TanglePrufTM Hinge design!

Shoe - Device fitted permanently to the bottom of ladders to prevent the ladder from slipping.

 

 

BS EN 131 - BS EN 131 is the British standard governing the specifications of ladders and stepladders constructed from aluminium, steel, plastics, and timber. Read more about the standard.

Static Vertical Load - Mechanical force that is applied slowly to an object (rungs or steps). Not to be confused with a Dynamic Load, which is applied rapidly (e.g: jumping or stomping).

Positive Locking Hinge - A device used in conjunction with a fastener to positively lock the fastener. This means the fastener cannot be loosened from vibrations or movements. Feature available on our WMP and FMP product range.

Dielectric Strength - A measure of the electrical strength of a material as an insulator. It is defined as the maximum voltage required to produce a dielectric breakdown through the material. Our fiberglass ladders have been tested for dielectric strength and it far exceeds the industry standard of 35 kV/in.
