The softline coating makes the knurled knobs GN 4534 particularly user-friendly and ergonomic. The soft, slip-proof contact area improves the contact both in hot (hand perspiration) and in dry ambient conditions, in the event of oily surfaces and even high or low temperatures. Besides its soft surface this knob has a large rim area which helps to distribute the operator’s contact grip and at the same time a higher torque can be reached.
