Vertical Track Installation, Plumb & Offset
Vertical Track Basics
The vertical track guides the door from the floor up to the curve section where it transitions to horizontal travel. Vertical track is installed on each side of the door opening, fastened to the jambs with lag screws or through-bolts depending on the wall construction.
The track offset is the distance between the inside face of the vertical track and the face of the door. Standard offset is 1/2 inch for most residential applications. This provides clearance for the rollers and hinges to travel freely without binding.
Plumb Verification
The vertical track must be perfectly plumb (straight up and down). Check plumb with a 4-foot or 6-foot level. An out-of-plumb track causes the rollers to bind, the door to be difficult to operate, and uneven wear on the rollers and track.
After securing the bottom bracket and the first track bolt, check plumb before tightening remaining fasteners. Adjust as needed using shims between the track angle and the jamb.
Pro Tip
Tighten the bottom bolt first, plumb the track, then secure the top bolt. Fill in middle bolts last. This makes adjustment much easier than tightening all bolts simultaneously.
Vertical track must be plumb with a standard 1/2-inch offset from the door face. Always check plumb before tightening all fasteners - bottom bolt first, plumb, then top bolt.
