seat rail diameters.

PRODUCT DESCRIPTION
The Drop Base is designed to provide stable base of
support for the individual who uses a seat cushion in
the wheelchair. Using the Drop Base on certain chairs
may allow the seat cushion to be recessed up to three
(3) inches (7.5 cm). The angle of the Drop Base can
be changed using the adjustable mounting clips. The
Drop Base lowers seat cushion height for improved fit
under tables or desks and improves foot propulsion.
The Drop Base is manufactured with universal
crossbrace cut-outs which allows the Drop Base to fit
most Invacare Manual (Model DBA) and Power
Wheelchairs (Model DBPA).
Adjustable height mounting clips allow for changes of
depth or angle in the field and also can be used for
clinical evaluation.
