About this product

• LOCK T MIDI – CONCEALED TIMBER-TO TIMBER CONNECTOR

Features & Functionality

• LOCK T MIDI is a perforated three-dimensional hook plate connector, which can be installed in a concealed, semi-concealed or visible configuration. The concealed version requires routing in the main element or in the secondary beam; the visible version does not require special cuts.
• The LOCK STOP lateral locking plates and the optional 45° inclined screw preventing pull-out allow certified resistances in all load directions according to ETA-19/0831 in each configuration. The connection with routing in the main element makes it compatible with fire resistance requirements.

  Key technical features:
  • In EN AW-6005A aluminium alloy
  • 14 sizes: from 50×135 mm to 125×290 mm
  • EVO version with graphite black coating, service class 3
  • ETA-19/0831 certified resistances: F_v, F_up, F_ax, F_lat
  • Compatible fasteners: LBS, LBS EVO and LBS HARDWOOD EVO screws with 7 mm diameter.

  Is LOCK T MIDI also suitable for inclined beams?

  Yes. The connector is designed for installation on inclined beams, with both horizontal and vertical inclination. Preassembly takes place off-site: on site the beam is lowered from above into the connector, without additional screws.

  When should the EVO version be selected?

  The EVO version is suitable for aggressive outdoor environments and for timbers with high tannin content, such as chestnut and oak. The graphite black coating ensures service class 3. In both versions, the choice of screw – martensitic stainless steel or C4 EVO coated – provides protection according to environmental corrosivity and timber aggressiveness.

  Are connections with LOCK T MIDI compatible with fire resistance requirements?

  Yes, provided the connector is installed with routing in the main element. In this configuration the surrounding timber provides the necessary passive protection. For fire design, refer to the technical data sheet and MyProject software.
