DImensions for 81-126

For old aluminum doors like this, the way to remove the rollers is to first knock off the bottom rail of the door frame. Once the screws are out, you would use a mallet and block of wood to gently tap off and remove the rail. Just be very, very careful. You want to use gentle (but firm) taps. The last thing you want to do is accidentally hit the glass.
