All Style Small Standard STD-Storm Collar Flashing; Fits Nominal Pipe Size (NPS) 1 -1/2 in. dia. (1.90 OD) round pipe.

Small STD-Storm Collars attach onto single, double or triple penetrations including sink/toilet vents, electric supply/return conduits and AC heat pump copper line set clusters. STD-Storm Collars are weatherproof roof flashing umbrella covers. STD collars provide a failsafe dam over a roof flashing opening which, if not closed, affords an avenue for flowing water access and passage into a buildings interior. Stopping water flow into a structure is especially important, and difficult to stop, as small conduits, pipes or insulated lines pass a single roof flashing site. This water flow can be kept on the roof via a Storm Collar cover atop a roof jack flashing. STD-Storm collars are not retro-fit. Access to the end of the penetration permitting a slide on installation is mandatory. Installation is easy. Insert the pipe, or group of pipes, into the pre-molded holes and close the clamps. Tightening the clamps produce the waterproof umbrella barrier. Rubber Storm collars will not corrode, fail, affect metallurgies and spring back from impacts. STD-Storm Collars are fabricated out of EPDM rubber that is exceptionally resistant to heat, ozone and acid rain for long life of over 20 years. A Roof Flashing is not part of the 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.
