    After decades of design and development, Rencol Components has established the UK’s most extensive range of plastic and metal hand knobs. Every application is accounted for; from fine adjustment control knobs for precision medical equipment, to heavy duty clamping knobs for oil rigs in the North Sea.

    When it comes to strength, durability, and resistance to corrosion, stainless steel is the ideal choice. Stainless steel has the advantage of being highly resistant to water, salt water, oils, and solvents. It can also endure high and low temperatures, and shock and abrasion.

    Rencol offers stainless steel knobs in numerous different styles, including, lobed clamping knobs, to mini star knobs, wing knobs and ball knobs. Design engineers will more than likely find a stainless-steel knob to suit their application, but if not Rencol is well placed to manufacture bespoke stainless steel knobs to a clients specification. Unique sizes, shapes and functions are all possible thanks to Rencol’s extensive manufacturing expertise.
