Metal Storm Collar 16 in - Heavy 26 Gauge Galvanized Steel

In this review of the Metal Storm Collar 16 in, the bottom line is simple: it is a basic, no-frills flashing collar best suited for installers who need a heavy galvanized steel option for single wall vent pipes. The reviewer found the collar's single biggest selling point is its construction from heavy 26 gauge galvanized steel, which provides reliable corrosion resistance for roof penetrations. This product is straightforward to fit over metal pipe flashings and uses an adjustable tab for a quick field bend, making it useful for roofers, HVAC technicians, and homeowners doing their own vent repairs.

Key Features

• Heavy 26 gauge galvanized steel: The material resists rust and is intended to withstand outdoor exposure at roof penetrations.
• Adjustable tab installation: A built-in tab can be bent over to secure the collar quickly without specialized tools.
• Designed for metal flashings: The collar diverts water away from the pipe to help prevent leaks at the flashing interface.
• Single wall vent compatibility: This product is intended for use with single wall vent pipes common on many residential and light commercial roofs.
• Range of sizes available: The collar is offered in sizes from 3 in to 18 in inner diameter so installers can pick the closest fit for the vent.

Who It's For

The Metal Storm Collar 16 in is aimed at professional roofers, HVAC contractors, and handy homeowners who need a durable galvanized steel collar for single wall vents. If the project requires a corrosion-resistant, straightforward collar that installs quickly with an adjustable tab, this model is a practical choice.

It is less suitable for users who require heavy gauge stainless steel, insulated or double-wall vent solutions, or precision-fit collars where a custom flange is necessary; some customers report fit and perceived sturdiness issues, so those needing a snug, heavy-duty finish may prefer alternative materials or custom-fabricated options.
