These Elesa Grip knobs, control knobs and handles represent their "SOFT' line; commonly known as "soft-touch', these new elements have been developed for use on machinery and equipment requiring frequent tightening, or for applications subject to severe stress. The major characteristics of "SOFT' products are to ensure a safer and more stable ergonomic grip and to improve the comfort of the operator's hand thanks to their soft coating which allows the absorption of vibrations even under unfavourable environmental conditions such as humidity, dryness, heat, cold and grease. They are suited to use with disability aids, high-precision instruments, fitness machines, horticultural and agricultural machines, and provide a secure hold where unfavourable climatic or industrial conditions may lead to problems of slippage.
