Softline standard parts feature a soft and slip-proof surface and provide better force transfer between hand and operating element – especially in moist, oily, hot or cold ambient conditions.
The Softline coating of knurled knobs EN 4534 makes them particularly ergonomic and easy to grip.
The soft, slip-proof contact area improves the grip both in damp (hand perspiration) and in dry ambient conditions, as well as in the event of oily surfaces and in very high or very low temperatures.
The use of knurled knobs is particularly recommended if frequent or strong tightening is required.
