The rail is always installed with the gear rack towards the
center of the stairs and gear teeth facing the wall.
The chamfered edges of the joint plate must face "up"
toward the bottom of the rail.
1. Attach the joint plate with the screws provided:
• insert (2) screws through the joint plate
from the underside
of the rail.
• insert (10) screws from the topside of the rail (see left).
2. Make sure the screw heads are flush with the surface of the
inside of the rail.
3. Mount the lower end cap.
RAIL JOINT ASSEMBLY
end cap
joint plate
2.5" (6 cm) from back
edge of rail to wall
.
If top or bottom clamp is omitted
(landing is cement or ceramic tile, or
the owner wishes not to drill holes in
the landing),
a set of clamps should
be added on the second-to-last step
and at the top of stairway.
POSITIONING
FOOT CLAMP
ASSEMBLIES
1. Loosely assemble the long bolt and nut to the clamp assembly. Do not
tighten the nut too far onto the bolt. Otherwise, it will be difficult to
install the upper clamps onto the rail. (see left).
NOTE: If the application calls for the rail to be set off the floor,
add the clamp wedge locks. See CLAMP WEDGE LOCK instruc-
tions later in this manual.
2. Place clamps in the pattern as indicated below.
Be sure to leave a minimum space of 2.5"* (6 cm) as measured
from the back edge of the rail to the wall.
* The 2.5" clearance is needed for the standard 67-degree seat swivel.
For installations involving the optional 90-degree seat swivel, the rail-to-
wall clearance increases to 3.5" (9 cm).
Frequently check the seat-wall clearance during installation.
clamp placement order
• bottom landing
• first tread up from bottom landing
• top landing
• first tread down from top landing
• closest tread above and below the rail joint(s)
• minimum of every third tread over remainder of staircase.
3. Set the rail on the loosely-assembled clamps.
On carpeted floors only
:
Place enough cardboard under the bottom end of the rail to raise
rail approximately 16 mm off of the floor.
4. Attach the upper clamp sections to the lower ledge of the rail.
5. Finger tighten the nut, bolt and clamp plates until the clamp plates
touch the rail.
6. Secure the clamps to the rail by tightening the long bolt and nut using
two wrenchs. Torque to 10 ft-lb (13.6 Nm). One to 1-1/2 revolutions on
the wrench will set the torque in the required range.
Do not overtighten the bolts! Rail deformation can occur.
