INSTALLATION INSTRUCTIONS:

The headrest clamp is secured to the wheelchair back using the hardware provided.
Whenever possible, the clamp should be installed into existing mounting holes in the
backpan. If no holes are provided, holes may be drilled in the desired location using
the mounting plate as a template 1 . An optional shim plate may be installed between
the clamp ass'y and the back pan to provide addtional clearance when needed.
The overall height of the headrest pad/ mounting post can be adjusted via the clamp
assembly. (note: once the final height position is set, the D-Ring (with set-screw)
should be adjusted so that it rests flush with the top of the clamp assembly (to prevent
slipping)).
The PHRK headrest pad is secured to the horizontal headrest rod via the mounting ring
and hardware provided. (note: the headrest pad can be adjusted to any desired angle
via the pivot ball at the end of the headrest rod by loosening and tightening the
mounting hardware).
The headrest (and headrest rod) can be further adjusted for depth and angle via
the triangular multi-offset bracket. To make adjustments, loosen the the hardware in
the multi-offset bracket, set headrest to the desired position and re-tighten hardware.
1 Important! - before drilling/modifying any backpan, be certain to contact the back
manufacturer to ensure the back is recommended to support a headrest application.
