Retro-Split Storm Collar®Retrofit Split Collar for Waterproofing Roof Penetrations

The Retro-Split Collar® is a storm collar that is used to waterproof roof penetrations that cannot easily be taken apart or disassembled. Our waterproofing Collars are designed to counterflash 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 Collars® open to allow an installation from the side. Our Collars have wraparound skirts with waterproof 'push together' locks. Plug Geometries for Storm Collars However, the secret to the versatility of the Retro-Split Collar® is the top plug geometry, which enables the Collars to conform to any shape. Virtually any geometry can be waterproofed using just a screwdriver. How simple does it get?

Retro-Split Collars® Retrofit Storm Collarswere created for angle iron supports that cannot be easily taken apart for top installations. There are instances where round, square, or angle iron posts are used for equipment screens, fences or signs. It is difficult to seal a round flashing around a square or angle post, giving professional roofers little choice in the past other than to use unreliable 'pitch pockets' for these locations, until now...

Retrofit Collar Assembly For Waterproofing Roof Penetrations
The Retro-Split Storm Collar® 'splits' open, allowing you to wrap it around the penetration. Once tightened with a hose clamp, you have a clean and effective waterproof assembly, as shown in figures 1-3.

We offer three sizes of Retro-Split Collars® which waterproof diameters up to and including 12 inches. The three sizes are 3 inches, 6 inches and 12 inches. This range of sizes can accomodate penetrations with any geometric shape that can fit inside 3, 6 or 12 inch diameters.
