All Style Industries Four Inch All Style Medium Standard STD-Storm collar Flashing for 4 inch Diameter (4-1/2 inch O.D.) Round Pipe

Medium STD-Storm Collars attach onto roof penetrations including roof vent, water, conduit and A/C cooling transition pipelines. STD Collars are weatherproof roof flashing umbrella covers. STD-Storm collars provide a failsafe dam over a roof flashing opening which, if not closed, affords an avenue for flowing water passage/access into a building’s interior. Stopping water flow into a structure is important, and difficult to stop as medium size pipes pass through a roof flashing site. It’s easy to insert a repair cover over broken, sun damaged or decaying pre-existing no-caulk flex flashings. Water flow is kept on the roof via a Storm Collar cover atop a new or failing roof jack flashing. Medium STD-Storm collar flashings are not retro-fit. Access to the end of the penetration permitting a slide on installation is mandatory. Installation is easy. Insert the pipe into the pre-molded hole and close the clamp. Tightening the clamp produce the waterproof umbrella barrier. Rubber Storm collars will not corrode, fail, affect metallurgies and spring back from impacts. Medium STD-Storm Collars are fabricated out of E.P.D.M. rubber that is exceptionally resistant to heat, ozone and acid rain for a long 20-year lifespan. A Roof Flashing is not part of the Medium STD-Storm collar package. Unequivocally, the easiest to install, and best-looking storm-collar on the market. Do-It-Yourselfers and Pros who have pride in their work, always use the best; an STD-Storm Collar flashing.
