Blind stick
A frame that is inserted into the shell as a falsework for door and window openings is called a blind frame or assembly frame .
Typically, a cane is of planks or squared timber manufactured and can be used to which, after completion of the shell door lining (Surrounding) of a door or window frame to attach a window in it.
In masonry construction , the upper transom of the blind stock is also used as a temporary lintel to support the masonry lintel until the mortar has set, or as a final lintel if it is sufficiently strong for this task.
Since large-format bricks and prefabricated lintels are mostly used today to erect walls, the use of a blind stick does not bring any great advantages. Door frames and window frames are screwed into the masonry so that they do not need to be attached to a walled-in dummy block.
If doors and windows are only to be used after the walls have been plastered (to protect them from damage during the construction phase, for example), dummy blocks can be plastered in first, to which the doors and windows can later be attached easily.
When installing windows in the insulation level, it can make sense to first attach a dummy block to the outside of the wall opening so that the window can then be attached to this solid frame.
