KT-RKV, TREDELAT

The Hahn KT-RKV is fastened with screws in the rebate as is common for butt hinges. Depending on the design of the profile sections, the 3-piece hinges are able to support doors weighing up to 120 kg, while the 2-piece version is able to bear up to 90 kg. These two series are fastened with the aid of self-drilling screws in the reinforcement of the frame profile with long pins to distribute the forces, acting on the hinge. In addition, Dr. Hahn also offers the option of pre-drilling into the prechamber alone – in other words only in the plastic – and supporting door leaves weighing up to max. 80 kg by using shorter pins and self-drilling screws.

Efficient processing in the workshop and at the building site

The mounting and removing of the door leaf is particularly easy and convenient with the 3-piece hinges. The upper hinge part can be easily mounted and removed in any position without having to loosen the fastening screws. Consequently, the door is mounted as with the 2-piece version and only then connected again with the upper hinge part. An important advantage for installation personnel on the building site. In case of a low door lintel the door leaf can be removed in the same way.

Both series can be adjusted in six directions with the door leaf installed:
The door leaf can be adjusted vertically +/- 3 mm
Horizontal adjustment of +/- 3 mm is also possible
Sealing pressure +/- 1.3 mm
