Mammut XT

90° corner – Inside corner

The Mammut XT inside corner 
is galvanised and has an alkus 
all-plastic facing.

The inside corner (Fig. 42.1) has 
tie holes. Only three assembly 
locks per joint are required for 
height 350 cm, all other heights 
require two assembly locks per 
side. The side length is 35 cm 
(Fig. 42.2) or 40 cm (Fig. 42.3), 
see page XT-38.

Inside corner 
with wood filler

The connection is achieved 
with three Uni- or RS-assembly 
locks for height 350 cm and 
with two assembly locks for all 
other heights. For stabilisation, 
an cross stiffener 44 must be 
attached with a flange screw 18 
to the multifunction profiles at 
each tie hole level (Fig. 42.4).
