Mounting Door Bracket and Arms
Step 12.1 - Alternative Mounting Option
The  opener  can  be  fastened  to  the  roof  by  driving  a  bolt 
through the C-Rail into a structural timber support. The bolt 
head’s height must not exceed 6mm (Fig. 20).
Step 13 - Mounting Door Bracket
The door bracket comes in two parts. The bottom plate with 
two mounting holes is used on its own for one piece doors. 
For sectional doors, the top plate is placed over the bottom 
plate and is fixed with four (4) screws (Fig. 21).
Mount the  door bracket,  or bracket  assembly,  on the 
door’s centre  line  one-third  down  the  top panel (Fig. 
21) using M6 or equivalent screws (not supplied), 
NOTE:  If  in doubt about  the  door’s  strength, 
reinforcement may  be added  to the  door’s 
frame  where  necessary.  Door  damage  may 
occur if the bracket is installed on a panel with 
insufficient strength. The opener’s warranty 
does  not  cover  damage  caused  to  the  door 
and/or door panels.
Step 14 - Attaching the Arms
FOR SECTIONAL AND ONE PIECE DOORS WITH TRACK: 
Assemble  the  bent  and  straight  arms  with  bolts  
and  nuts  supplied  in  the  accessory  pack  (Fig.  22).  
Always use both bent and straight arms.
Connect  the  assembled  arm  to  the  bracket  and  the 
disengaged trolley with clevis and snap pins. The angle 
“A” must be more than 10° (Fig. 22).
WARNING: Connecting the bent arm other 
way around may damage the door.
FOR ONE PIECE DOORS WITHOUT TRACK
Assemble the bent and straight arms as shown in (Fig. 
23) with bolts and nuts supplied in the accessory pack.  
Always use both the bent and straight arms.
Connect  the  assembled  arm  to  the  bracket  and  the 
disengaged trolley with clevis and snap pins. 
If installing on a door with a bad wave action, lengthening 
the arm will assist in reducing this effect.
