The TENAX is a kind of push button with triggering self-lock. When it is closed by pressure, the upper and lower part are so firmly connected to each other that you cannot separate them again without pressing the lock lock. Therefore, the TENAX is particularly suitable when a quick and easy release, but load-proof closure is desired. For example, for removable grates in kitchen furnishings, as a lid closure for containers, for secure attachment of machine panels, or as wind deflectors and trim attachments to convertibles and caravans. The construction and function of the TENAX are uncomplicated. Just like the Loxx push button, its construction is based on a 19th century English patent. Its mechanism is largely encapsulated and therefore not susceptible to interference. The closure is particularly suitable for frequently released connections to utility items such as for securely attaching tarpaulins, covers and other covers. The small dimensions result in economical installation options. For special applications, custom designs are also possible. The box contents of the Tenax set consists of: 10 x Tenax top/button large, 10 x Tenax lower part/threaded screw M5 x 10 mm and 10 x M5 nuts.
