FITTING THE J2 DEEP CONTOUR BACK
TO THE WHEELCHAIR
The J2 Deep Contour Back was designed to fit on almost any
wheelchair design. It has 6 different top hook options and 3 bottom
pin options which allow it to be installed on various width wheel-
chairs. This capability enhances the fit of the Back to the body and
the fit of the Back to the wheelchair. Long and short hooks are
used to help increase or decrease recline. Short hooks are used in
conjunction with back posts that have a bend in them. Long hooks
are used with straight back posts. Additionally, there are short and
long 1/2" and 1" (1.2 and 2.5 cm) offset hooks. The off-set hooks
make it possible to install a narrower back on a wider wheelchair.

INSTALLING THE DEEP CONTOUR BACK
The J2 Deep Contour Back is designed to replace the wheelchair's
sling upholstery. The initial installation should be done without the
foam insert in the Back shell. Tighten all fasteners to 20 in.-lbs. (2.3
N.m) using a Phillips No. 2 screwdriver.
Installing the bottom Universal Post Bracket hardware
1. Remove the upholstery from the back of the wheelchair.
2. Attach one bottom universal post bracket to the bottom of
each back post of the wheelchair. (Diagram1)
a) The universal hardware is designed to fit on 5/8", 3/4",
7/8" and 1" (1.6, 1.9, 2.2 and 2.5 cm) diameter back post
tubing. (The bracket comes assembled to attach to 7/8"
or 1" {2.2 or 2.5 cm} tubing.) Check diagram 1 to deter-
mine which strap hole is appropriate for the installation.
Wrap the strap around the wheelchair post. Screw "A"
may have to be loosened to align the strap hole with the
barrel nut located inside the post bracket body. Place a
washer on screw "B" and insert the screw through the
appropriate hole in the strap.
b) Tighten screw "B" into the barrel nut through the side
of the post bracket body. Tighten the opposite screw
if necessary.
c) Snap the screw caps over both screw heads.
d) To adjust the height of the bracket, loosen screw "A" until
the bracket slides freely on the back post. Once the
proper height of the back is determined, tighten the
screw. All future adjustments of the back height are done
with screw "A".

See the matrix below for appropriate back to chair guidelines. Also,
1/2" and 1" (1.2 and 2.5 cm) extended bottom pins are available to
accommodate installation on a wider wheelchair. Consult your
Medical Equipment Supplier for help in ordering and installing
optional hardware or call Jay Customer Service for more informa-
tion. 1-800-648-8282.
NOTE–
The widest and narrowest settings are accomplished by adjusting
the top adjusters and bottom pins. The short and long hook options
do not affect any width adjustment dimensions.
CAUTION– Do not use the off-set hook & pins to mount the J2 Deep Contour
Back to a wheelchair wider than 20" (50cm). This may cause the
back to fail as it is not designed to accommodate chairs with user
weight ratings exceeding 250 lbs (113kg).
