The TENAX is a kind of push button with self-locking triggering. When it is closed by pressure, the upper and lower parts are so firmly connected to each other that you cannot separate them without pressing the lock lock. Therefore, the TENAX is particularly suitable when a quick and easy release, but load-safe closure is desired. For example, for removable grates in kitchen facilities, as lid closure for containers, for secure attachment of machine cladding or as wind deflector and tarpaulin 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 prone to interference. The closure is particularly suitable for frequently loosened connections to everyday objects such as for the secure attachment of tarpaulins, hoods and other covers. The small dimensions result in affordable installation options. Customer-specific designs are also possible for special applications. The box contents of the Tenax set consists of: 10 x Tenax top/button large and 10 x Tenax bottom/tapping screw 4.2 mm x 16 mm.
