ADJUSTABLE HANDLES

Adjustable handles are particularly useful as clamping elements when the lever turning angle is limited owing to lack of space.

 For clamping, lift the lever to disengage the clamping device teeth and bring it back to start position.   

By releasing the lever, the return spring automatically engages the teeth.

The two main components of an adjustable handle are the lever and the clamping element

- the lever is the element used by the operator, it can be made out of technopolymer or metal (die-cast zinc alloy or steel). technopolymer lever may have internal teeth moulded in technopolymer or in zinc alloy (overmoulded insert).

- the clamping element has got a toothed element which matches the lever body and can have a threaded hole or a threaded stud. It can be made out of technopolymer with metal insert (threaded hole or stud) or totally made out of metal according to the lever toothed element.

 

To ensure the toothed element works properly, the two sets of teeth (of the lever and the clamping device) have to be made out of the same material.

Based on the material of both the lever and the clamping element, the following versions are available.

- technopolymer lever body and clamping element (the two toothed elements are made out of technopolymer);

- technopolymer lever body and metal clamping element; in this case, the technopolymer lever has got a zinc alloy toothed insert in order to ensure a perfect match between the metal teeth of the clamping element and the technopolymer lever;

- metal lever body and clamping element.
