GN 300.4
Adjustable handles with high tightening clamping force

RoHS compliancy

The majority of the standard products available in the ELESA catalogue are compliant with the European Directive 2002/95/CE (RoHS directive, Restriction on Hazardous Substances).

However, there are some exceptions for some products which are not yet compliant owing to technological limits in the field of research in raw materials hence not due to ELESA's direct responsibility.By clicking on each product code in the table, you can directly check the status of the product as to RoHS compliancy.

All compliant products are supplied with a label showing the RoHS symbol.

Lever body
Zinc alloy die-cast, epoxy resin coating.

Colour
RAL 9005 black, matte finish.

Distance bushing
Nitrided tempered steel with balls allowing a greater efficacy of the clamping force.

Standard execution
Black-oxide steel clamping element with threaded hole and retaining screw. Steel return spring.

Special executions on request
- Lever in different colours.


Features and applications
Adjustable handles GN 300.4 allow a higher tightening clamp force. The clamping element is not in direct contact with the plane to be clamped. Clamping is made by the distance bushing with large base, which does not rotate on the plane. The bushing contains a set of balls which reduce to a minimum friction between the part which rotates with the lever during clamping and the distance bushing.

Instructions of use
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.
If the lever cannot make a 360° rotation, the clamping element can be easily screwed by means of the hexagon socket front head screw (after having disengaged the lever).
