- Install First Rail Starting at Bottom of Shaft ("King
Rail") [Interlock Side].
- Start at bottom of elevator shaft using the rail on the
interlock side of that door opening. This rail will have the
tamper resistant plugging device trigger attached to it. This
rail is the "King Rail" for that opening.
- Use the DBG rod to determine the approximate opposite (Queen)
rail positioning on the jambs. Mark the King Rail location
on the jamb with pencil.
- Using (2) steel carpenter clamps, clamp rail to jamb.
- Line up vertical sill mark of King Rail with landing sill's
lowest point across the opening.
- Line up pencil line on jamb with outer edge rail.
- Plumb rail with Plumb Bob.
- Make final adjustments and use 4' level to check vertical
- Attach top and bottom of rail with rail bolts.
- Drill holes with a 11/32" high-speed drill bit.
- Use masonry bit and hammer drill to clean out the
- Bolt rail in place (do not use washers).
- Self-tapping rail bolts are provided. To use, spray
lubricant into drilled hole and drive bolt in place
with a hammer drill using the 9/16" heavy-duty
- Remove clamps.
- Fasten remainder of rail with rail bolts, making sure these
bolt heads are positioned at top of their rail slots. Biparting
doors are heavy and could pull the rails down from their proper
location if the bolts are not at the top of the rail slots.
- If necessary, add rail shims to fill in any spaces between
rail and jamb to ensure plumbness. Back out rail bolts one
by one and insert rail shims until space is filled.
