Chimney Lining Components
SUPPORT PLATE
The Support Plate is used as a base support or as an
intermediate support to take the weight of up to 15m of Prima
Smooth, when used as a chimney liner.
It is used in conjunction with cantilever brackets. The spigot
below the plate is constructed from adjustable pipe to allow
for thermal expansion within the system. The plate is notched
at the back to allow the plate to slide into the correct position
as required using the full length of the cantilever bracket. The
support plate is then attached to the cantilever brackets using
the bolts provided through the fixing slots in the top plate.
CANTILEVER SUPPORT
Once the position of the support has been established within
the chimney stack, secure the cantilever brackets to the wall
using expansion bolts to ensure adequate attachment and
support.
