Definition
The vertical framing on each side of the garage door opening that the track brackets and hinges anchor into. Jambs take real load — every pound of door weight and spring force ultimately pulls on them — so soft, rotted, or split jamb lumber is a problem that has to be fixed before new hardware goes up. Wet springs and snow piled against the garage rot jamb bottoms first, which is why installers probe them during any Door Serv Pro replacement estimate.
