SUSPENSION BAND (SB)
1. Suspension band is used to support and guide the chimney in
horizontal runs. It consists of a band, a flexible strap (by others), a
trolley and a rail.
2. The trolley and rail allow up to 4” of travel to compensate thermal
expansion.
3. See section A, Table 7 for maximum distance between two supports
or guide.
4. Important: The flexible strap must be at least 3/4” wide and 0.036”
thick made of galvanized or stainless steel. YOU MUST USED TWO
LAYERS OF FLEXIBLE STRAP to attach the band to the trolley.

CRADLE SUPPORT (CS)
1. Cradle support is used to support and guide the chimney in horizontal
runs. It consists of a cradle support and suspension rod (by others).
2. The suspension rods must attached to the structural members to
provide rigidity.
3. Cradle support allows to stack two (or more) horizontal chimney
runs (See Figure 33).
4. Cradle support does not allow movement for thermal expansion.
This support should be used for low temperature application.

FLOOR GUIDE (FG)
1. The floor guide is used the same manner as the wall guide but it is
modified for use at floor penetrations. See Figure 30 (floor guide).
