Base Model: DBP A).

Adjustable mounting hooks allow for changes of depth, height
or angle in the field and also can be used for clinical evalua­tion. Refer to ADJUSTING INFINITY DROP BASE in this

INTRODUCTION

The Drop Base is designed to provide a stable base of sup­port for the individual who uses a seat cushion in the wheel­chair. Using the Drop Base on certain wheelchairs may allow
the seat cushion to be lowered up to two (2) inches (5 cm).

NOTE: Refer to the INSTALLATION WARNINGS in the
SAFETY SUMMARY of this instruction sheet.

1. Install rail clamps onto the wheelchair if not already in­stalled. Refer to instruction sheet part number 1074563.

2. Determine necessary position of the seat for the user.

NOTE: This includes seat width, height, angle and depth.
NOTE: HEIGHT - The amount of drop on each wheelchair

varies depending on style of wheelchair (Hemi-height ver­sus Standard height). On some wheelchairs, the crossbraces
may hit the Drop Base preventing maximum drop.

NOTE: ANGLE - The base brackets may be positioned UP
or DOWN (Refer to FIGURE 1). Base Brackets are factory
installed in UP position.

NOTE: ANGLE - Front mounting hooks may be positioned
1-inch higher or lower than rear mounting hooks.

NOTE: DEPTH - It may be necessary to reposition the front
base brackets forward and/or rearward to secure the drop
base to the wheelchair with the rail clamps. Front Base Brack­ets are factory installed in rearward position.

3. Refer to FIGURE 1 for the following:
A. Determine if base brackets need to be repositioned

to correspond to seat position.

B. Determine corresponding mounting hook mount-

ing holes for seat position.
