Installation

Routing is necessary on 1 side only. This routing should be 15 mm deep, 90 mm wide and 220 mm long as a minimum.

The distance between the ICST and the end of the timber elements should be 100 mm as a minimum.

ICST is composed of two parts, which will be face to face in final position.

The guiding central part of the connector facilitates the timber assembly.

The ICST is preconized in the case of "closed" walls (exterior and interior wall coverings installed).

Options

Free for different slopes and skews, only the gap has to be in one plain.
It´s to check the mounting sequence of the wall elements, because for the mounting is always drop down one to the other element.
