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?????

Well the motor is already attached...another fun issue. The supports run
horizontal rather than vertical. So we had to saw out a path from the door
to the motor for the track.

We just were not sure if we were going about it the right way. Neither of
us could recall seeing a bolt poking out of the front of someone's door.
That seemed wrong. The other concern is that since it is the type of bolt
that has the "square" between the rounded head and the cylindar threaded
part, we didn't know if once tightened if it would just rip through the
door.

So this is correct so far?

Thank you :-)
