The standard rotary adjuster is equipped with a quick adjustment. For this, loosen the screw that is located at the side of the rotary plate. The rotary unit is essentially made of stainless steel. The adjustment button is made of black anodised aluminium, the worm bearing of sinter bronze.
The heavy duty rotary adjusters with hollow shaft are made of stainless steel and aluminum. They work with a high-quality worm gear whose backlash can be minimised through infeed of the worm wheel or worm. The hollow shaft allows the engineer additional flexibility to hide tubes and cables.
