Useful – whatever way you twist and turn it
Typical for Knipex: this multifunctional key shows how useful a tool can be when it is from Knipex. Irrespective of how you twist and turn it and what your objectives are when using it, this locking tool impresses the user through its many uses despite its compact size. An external square and key for four more types of closing are integrated in the tool.
Unlock the control cabinet, open the cover, press the heating valve
The range of applications for this multifunctional tool are diverse. The Knipex Twinkey can be used both at home and in a professional environment. Typical uses at home include bleeding radiators, opening a skylight secured with square profile or screwing Phillips and other screws. Professional applications using the Twinkey (for authorised staff) include opening and closing control cabinets in electrical engineering, on air conditioning and on shut-off systems. They can also be used to open service hatches and operate locking devices.
Compact tool for powerful twisting
A strong locking tool is a great advantage, particularly in the case of stiff locking systems. Thanks to the large contact area (spider key) with good grip, the Twinkey sits well in the hand and can be used for powerful rotating movements on the locking systems you want to turn. The compact size with a length of 92 mm gives you good access with the Twinkey to diverse types of locking systems even in confined spaces.

Tools from Knipex: benefits that are plain to feel and see.
Large tool benefits, compact for putting in a jacket or tool bag. The Knipex Twinkey, which weighs just 135 g, combines 13 different tool applications. As with all other tools from Knipex, this universal key is also an example of intelligent solutions right to the last detail. A magnet holds the two spider keys on the Knipex Twinkey together in a space-saving way for transporting and storing it in a work jacket, tool bag or case. During use, the keys are separated and held – with the reversible bit – by a stable stainless steel wire.
