Introduction 1
1.0 Introduction
The Rice Lake Mechanical Chair Scale is designed for those who have a difficult time standing on a scale. It is
ideal for use in clinics and nursing facilities. The scale is durable, having a sturdy enameled steel body, a molded
polypropylene chair, heavy-duty footrest and heavy-duty caster wheels for easy portability.
The Rice Lake Mechanical Chair Scale comes in two models:
• RL-MCS-LB (450 x 4 oz capacity)
• RL-MCS-KG (200 x 100 g capacity)
Manuals can be viewed and downloaded from the Rice Lake Weighing Systems website at
