A friend was trying to install a garage door by himself. He's having some
trouble, so I thought I'd help. I know nothing about repair, but know about
newsgroups, so I thought someone here could help. He has a sectional door
(CHI Model 2241) and is installing a Craftsman 1/2 HP Model
139.53982SRT/139.53995SRT.

According to Step 11 on Page 24 of the manual, it discusses the installation
and fastening of the door bracket. How does one do this? According to
Figure 2, it looks like you drill through the front of the door and put the
Carriage Bolt through the whole door. The bolt is longer than the door is.
My friend, thinking this, drilled a hole through the door and then realized
then the mistake that may have been made.

So I guess this would be a two part question. First, how do you attach the
door bracket and second, if it doesn't require drilling through the whole
door, how do you patch a door?

Thanks in advance.
the install booklet shows you that you drill through the top wooden
piece of the door and then attache the two bolts there holding on the
bracket so that when the opener pulls back on the top of the door that
the door will come up... on mine the door is about 2 inches thick wood..
if you have metal and its real thin(like 1/16 to 1/8 in. thick then you
should use a backer board(piece of 2 by 4 inch wood for some length
inside the door so the bracket can be attached to it....
gee if this is what is stopping him, what is he gonna do when it comes
time to attach the opener case through the ceiling and the angle bracket
metal to the ceiling joist/or rafter supports?????
