Only original parts of the ladders and/or fixing materials from our firm may be used. 
Material and/or product liability cannot be granted in case of improper assembly or the use of outside  
supplied parts and/or modifications.

Assembly of the tube holders to masonry or plasterboard walls: 

 

Version 1: 

Place a sleeve with an M8 internal thread and tighten the holder  
via the provided M8 grub screw and align it so 
that the semi-circular recess is on top. 

 
Version 2: 

Place the dowel into the wall and tighten an M8 threaded pin (length of approx. 70mm)  
so far into the dowel until only 15 mm show. Then tighten the holder onto the threaded pin and align it so 
that the semi-circular recess is on top.
