| Eliminates the requirement to remove old roof outlets by fitting directly into the existing outlet, creating a watertight seal within existing pipe. The outlet is fully insulated and appropriately raised, to match the thickness of new roof insulation layer. The bottom flange should be sealed down onto existing roof covering, using a sealant compatible to the roofing material or a bonded membrane strip, to achieve a secure moisture barrier. The outlet includes a membrane clamping ring, dome grate, connection pipe and seal. Supplied with full installation instructions.
