[Spridgets] garage door

[Bob Van Kirk]

 As a side note to those who have automatic garage door openers and windows in
the garage door, it is very easy for someone to break the window and reach in
a trip the emergency release and then just open the door.    While on extended
trips away from my house I remove all the openers from the remaining vehicles
and then use padlocks on the door tracks so the door can't opened either by
the above method or by someone roaming the neighbor randomly trying different
openers....

I keep hearing people to the red handle cord as an emergency "stop" or

"release" cord.  It disconnects the door from the drive.  If you
haven't set
the balance spring correctly, pulling the cord simply lets the door fall or
rise without any interference from the motor, eliminating any chance for the
auto-safety mechanism to work.  If the springs heven't enough tension to
balance the door's weight, then pulling the red handle will send the dorr
straight down onto whatever is below it.  Set the balance springs to more
than equal the door's weight, and pulling the handle will let the door go
right back up.  Good failsafe.  This refers only to the sectional doors that
go up into tracks and have a big coiled spring residing above the door.  The
normal single panel door can also be adjusted with the correct springs to
weigh "less" or "more" to suit.  With the automatic opener
on a single panel
door, I'd use strong springs that tend to open the door if it isn't
held
shut.  Tho opener will have to work to close it, but a failure or red handle
pull will not send the door crashing down on you or your precious LBC.
