Secure to rafter with 2 lag screws (sold
separately). Secure L-foot or installer-supplied
strut directly to standoff with standoff
hardware. Especially convenient when
installing over a tile roof because flashing
can be precisely fitted over secured base
prior to installation of shaft.

Flashing refers to thin, continuous pieces of sheet metal or other impervious material installed to prevent the
passage of water into a structure from an angle or joint.
Flashing generally operates on the principal that, for water to penetrate a joint, it must work itself upward
against the force of gravity or in the case of wind-driven rain, it would have to follow a tortuous path during
which the driving force will be dissi-pated.
Unirac offers flashings to be used specifically with Unirac standoffs. These flashings are collared, thereby
eliminating the need for the use of sealant between standoff and flashing. The flashing slides over the standoff,
under the shingle above, and over the shingle below.
The following installation instruction provides an explanation of planning and installation of two different
applications.
