CONTOUR CT28 WALL & CEILING INSTALLATION

Figure   125.  Tightening  the  locking  bolt  on  the 
opposite side (-40° shown).

Once  the  two  primary  bolts  have  been  inserted  to  fix  the  tilt 
angle,  the  secondary  bolts  should  be  inserted  on  each  side 
and threaded into the remaining inserts on the bracket. These 
WILL NOT enter holes on the external plates of the bracket, but 
will  come  into  contact  with  the  external  surface  of  the  plates, 
between the holes.

Figure  126. Inserting the secondary bolts (-40° tilt 
angle shown).

When these two secondary bolts are threaded into the Bracket, 
use a 4 mm hex wrench to tighten them securely. These two 
secondary bolts serve to lock the two components of the bracket 
together and prevent the external plate from slipping over the 
head of the primary bolt, in case of unforeseen lateral or vertical 
forces strong enough to flex or bend the bracket.

angle shown).
