The SF-ABC1020 delivers a 10-A:120-B:C rating in a 20 lb. form factor, providing significantly greater suppression capacity than standard 10 lb. units while remaining portable for single-operator use. Its 90% MAP agent formulation, 235 PSI operating pressure, and 28-second discharge time give contractors a longer, more powerful discharge window compared to smaller-capacity alternatives. The 6-year warranty and compliance with both U.S. and Canadian standards make it a practical choice for cross-border jobsite operations.
Key Features & Benefits
Modified Universal Valve Body
The modified universal valve body accepts both pin and fork wall hooks, providing installation flexibility across a wide range of mounting configurations. This reduces the need for additional hardware on varied jobsite setups.
Steel Cylinder with Super Durable Polyester Powder Paint Finish
The steel cylinder is finished with a super durable polyester powder paint coating that provides superior corrosion resistance. This is critical for extinguishers stored in outdoor, marine, or high-humidity environments where lesser finishes would degrade.
Waterproof Stainless Steel Gauge
The waterproof stainless steel gauge maintains accurate pressure readings even in wet or corrosive conditions. Contractors can perform quick visual inspections without concern for gauge failure due to moisture ingress.
Reinforced Full-Grip Hardcoat Anodized Aluminum Handle
The handle is reinforced and features a full-grip hardcoat anodized aluminum construction for durability and secure handling under stress. A firm, reliable grip is essential when operating a 35 lb. extinguisher in an emergency.
Oversized Pull Pin with Retaining Strap
The oversized pull pin with retaining strap is designed for easier and faster activation, reducing fumbling time in an emergency. Faster activation can be critical in the first seconds of a fire event on a jobsite.
Color and Bar Coded Labels
Color and bar coded labels support accurate service and inspection tracking. This simplifies compliance recordkeeping for contractors required to maintain fire equipment service logs.
Wide Operating Temperature Range
Rated for use from -65°F to 120°F (-54°C to 49°C), this extinguisher remains operational in extreme cold and heat. This makes it suitable for year-round use across Canadian and U.S. climates without seasonal equipment swaps.
U.S.C.G. Approved
U.S. Coast Guard approval with bracket listed on label qualifies this unit for marine and vessel applications. Contractors working on waterfront, marine construction, or vessel fit-out projects can use this extinguisher to meet marine fire safety requirements.
Common Applications
Class A Fire Suppression — Wood, Paper & Cloth

Class C Fire Suppression — Electrical Equipment
Suitable for use on energized electrical equipment, covering panel boards, wiring, and powered tools encountered on active jobsites.
Marine & Vessel Applications
U.S.C.G. approved with bracket listed on label, qualifying this unit for use aboard vessels and in marine construction environments.
