Lever body

Glass-fibre reinforced polyamide based (PA) technopolymer, in Elecolors colours, matte finish.

Push button

Technopolymer in Elecolors colours, glossy finish.

Standard executions

Glass-fibre reinforced technopolymer clamping element with retaining pin, black colour, with knurling on the protruding part to make initial tightening easier. AISI 302 stainless steel return spring.

ERX-B: brass boss, threaded blind hole.

ERX-SST: AISI 303 stainless steel boss, threaded blind hole.

ERX-p: zinc-plated steel threaded stud, chamfered flat end UNI 947 : ISO 4753 (see Technical data).

ERX-SST-p: AISI 303 stainless steel threaded stud, chamfered flat end UNI 947 : ISO 4753 (see Technical data).

Features and applications

Particularly suitable when the lever turning angle is limited owing to lack of space.

Compared to other types of adjustable handles with metal retaining screw this solution offers:

absolute electric insulation for the operator
no visible steel parts subject to rust
more comfortable lever release.

Stress resistance

Adjustable handles are generally used for repetitive clamping operations sometimes with very high-frequency.

Therefore, the stress resistance (i.e. the resistance to repeated tightening cycles) of the handle unit is particularly important and, especially, the strength of the toothed element which transmits the tightening force from the handle to the threaded element (boss or stud).

In fact, the results of several laboratory tests, perfomed with a special instrument that simulates the most severe use conditions, have shown that e.g. ERX.78 adjustable handle can withstand without yielding more than 100,000 tightening cycles, under the action of a force of 490 N (see graphic).

The special glass-fibre reinforced technopolymer enables the ELESA adjustable handles to guarantee stress resistance values which are much higher than the ones generated under normal working conditions.

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.
