A NOTE ABOUT QUICK-RELEASE CASTERS

Quick-release casters are an option that allow for quick and easy removal of the casters from the
wheelchair so the wheelchair can be stored and transported conveniently. When using the quick-
release caster option, a spring loaded caster head tube cap will be used instead of a stem nut to
secure the front caster to the chair frame. Unlike the stem nut, the caster head tube cap is not
adjustable and thus caster flutter will be more evident with the quick-release caster option than it
would be with the standard caster attaching hardware.
