CAUTION
Install these reels at a height no greater
than ft (6.1 m) from the floor to
comply with the warranty.
Hose reel models -B, -B, and

of feet (15.2 m) of hose and be mounted
to the wall, ceiling, or floor.
The reels mount as a single unit or in
banks of as many as required. Banked reels

mended (→ fig. , page ).
Each model reel is spring-powered and
self-retracting. When the hose is extended,
the reel can be latched on either of two
ratchet sections per revolution of the sheave.
A pull releases the latch from the ratchet and
allows the hose to retract onto the reel.
