LOCK T MIDI: STRONG, SAFE, REMOVABLE, SUITABLE FOR AGGRESSIVE ENVIRONMENTS.

LOCK T MIDI consists of an aluminium alloy three dimensional perforated plate. The connector can be installed in a variety of configurations: with grooving in the main element or secondary beam for a concealed installation, or without special cuts for an exposed installation.

The LOCK T MIDI timber-to-timber joint plate is available in two versions: standard or EVO, painted in a particular graphite black colour for its performance. Both versions can be used with three varieties of screws: martensitic stainless steel, carbon steel and C4 EVO coated. The ideal combination of connector and screw fulfils all fastening requirements, such as aggressive environments or the presence of aggressive timber containing tannin, such as chestnut and oak.

The LOCK STOP lateral locking plates and the vertical anti-slip screw provide certified strengths in all directions in each configuration.
The grooved joint in the main element makes it possible to fulfil the fire safety requirements.

Thanks to the assembly with only one type of screw, installation of LOCK T MIDI is quick and easy. The two parts of the connector can be pre-installed on timber elements off site, without the need for on-site fastening.
