Raise opener and support it so that the garage door may be moved to its full open position. The
best support would be the top of a step ladder if the door can move freely under the rail. If this is
not possible an assistant will have to support the opener until the door can be opened.
Once the door is fully open the
opener can be supported by a 2” x
4” board laid across the open
garage door. Be sure the door is
strong enough or support the
center to prevent sagging of the
door.

DOOR END OF RAIL. BE SURE DOOR
WILL CLEAR TROLLEY BEFORE
ATTEMPTING TO OPEN THE DOOR.

terbalance system it will be necessary to

stepladder or other temporary support to
attach the front end of the rail assembly
