The REVOLU TFNA has straight rafters, received by a strong gutter beam on the outside. Posts attach under this beam and can move left or right to accommodate a specific post location. The width can be seamlessly extended without limit. Regular width is 12β, but 18β units can be ordered as well. Maximum Projection is 20β.
REVOLU General Properties:
Projections 3β to 8β have a Panel-width of 36β
Projections 9β to 20β have a Panel-width of 18β
Rafter sizes are specifically designed to accommodate these projections. Shop drawings and specific structural reports are available from Japan.
A Japanese Patio Cover is ordinarily attached straight to a house wall. It can however, if needed, be mounted on top of a roof with special ledgers and brackets.
