Special conversion arm for use with the Life Probo garage door automation kits on up and over canopy garage doors.
Life Probo kits need no additional parts to work on segmented garage doors and up and over garage doors that fully retract into the garage when open.
However, the nature of up and over canopy garage doors means that an alternative arm is required for mounting the mechanism to the door.
How to check your canopy door.
If your garage door is not made of sections and retracts fully into the garage when open, It is s standard up and over door.
If it has the same, one piece construction but does not fully retract into the garage when open (creating a canopy over the entrance to your garage), your garage door is a canopy door and you need this conversion arm.
