MR.

Glass-fibre reinforced polyamide based (PA) technopolymer, black, orange, grey colours, matte finish.

Standard executions

Glass-fibre reinforced technopolymer clamping element, black colour, with knurling on the protruding part to make initial tightening easier.

• MR-A: black-oxide steel boss, plain or threaded blind hole. Black-oxide steel retaining screw, AISI 302 stainless steel return spring.

• MR-B: brass boss, threaded blind hole. Brass retaining screw, AISI 302 stainless steel return spring.

• MR-p: black-oxide steel threaded stud, chamfered flat end UNI 947 : ISO 4753 (see Technical data). Black-oxide steel retaining screw, AISI 302 stainless steel return spring.

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

MR. adjustable handles can be quickly screwed during assembly by means of electric or pneumatic screwdrivers with controlled tightening torque system.

Stress resistance

See ERX.

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).
