All Style Industries patented Retro-Split™ Storm Collar (# 6640503 & 6591561) are used to weatherproof roof penetrations that cannot easily be taken apart or disassembled. These storm collars are designed to counter flash a roof jack flashing that has been installed into a roofing system when an "over the top" installation is not possible or desired. Retro-Split™ Storm Collars open to allow an installation from the side. By utilizing a patented "push together" skirt lock the collars can wrap around any geometric shape penetration.
