Step 1: Remove sling
rail caps
Remove the sling rail caps from
the chair. A flat-head
screwdriver and a hammer may be
required.
Step 2: Remove Bolts
from One Side
Remove the bolts holding one
side of the sling rail to the
chair frame. Most manufacturers
use a 1/4" x 20 thread bolt; a
7/16" socket or a 3/16" hex head
socket is usually effective. Use
a ratchet to break the bolts
loose, and remove them with a
drill socket. (Figure 1)
Step 3: Remove support
bars
The chair may have support bars.
If they are straight, spread the
sling rails apart by using a
screw clamp that stretches
instead of squeezes. If the
support bars are curved, pull on
the center while pushing on one
end of the bar near the sling
rail. (Figure 2)
Step 4: remove the old
sling
To remove the old sling, pull it
through the sling rail.
Sometimes a pair of pliers makes
this job easier. If the sling
will not be used as a pattern,
cut it down the middle and
remove it. (Figure 3)
Step 5: install the new
sling
Insert the sling spline through
the sling pockets (one on each
side). Starting at the top,
insert the sling into the sling
rail; slide the sling to the end
of the rail. (Figure 4)
Step 6: replace the
bolts
Lay the chair on its side and
replace the bolts using the
drill socket. If the bolt does
not reach the chair frame,
loosen the bolts on the opposite
sling rail, then tighten all the
bolts. (Figure 5)
Step 7: finish
Complete the Job Re-install the
support bars (if any) and cut
the excess sling spline (Figure
6). If the support bars are
curved, it may be necessary to
hit the curve dead center with a
rubber mallet to tighten the
support bar. (Figure 7) Replace
the end caps.
