Technical Specifications

Strike First ABC Series — Full Model Comparison

The SF-ABC110ST's compact 2.5 lb. form factor and dual wall/vehicle-marine bracket compatibility make it the practical choice when space is limited but tri-class coverage is required. Its 90% MAP agent concentration and hardcoat anodized aluminum handle set it apart from lower-specification units, while the modified universal valve body accepts both pin and fork wall hooks for flexible installation across a wide range of mounting scenarios.

Key Features & Benefits

Modified Universal Valve Body

Accepts both pin and fork wall hooks, giving contractors flexibility to mount the extinguisher in virtually any bracket configuration without sourcing specialty hardware. This simplifies compliance across multiple job sites or vehicle types.

Steel Cylinder with Super Durable Polyester Powder Paint Finish

The steel cylinder is finished with a polyester powder coat that provides superior corrosion resistance, keeping the unit serviceable in harsh outdoor, marine, and industrial environments. Durability of the housing directly reduces replacement frequency and total cost of ownership.

Waterproof Stainless Steel Gauge

The stainless steel pressure gauge is waterproof, allowing quick visual pressure checks even in wet or exposed conditions. Contractors can confirm readiness at a glance without removing the unit from its bracket.

Reinforced Full-Grip Hardcoat Anodized Aluminum Handle

The handle is reinforced and hardcoat anodized for strength and grip retention under stress. In an emergency, a secure, non-slip grip is critical to effective deployment.

Oversized Pull Pin with Retaining Strap

The oversized pull pin with retaining strap is engineered for easier and faster activation, reducing fumbling under pressure. Faster activation can be decisive when seconds count on a job site.

Color and Bar Coded Labels

Color and bar coded labels support accurate service tracking and inspection compliance. This simplifies record-keeping for contractors required to maintain documented fire safety programs under NFPA 10.

Extreme Temperature Range

Rated from -65°F to 120°F (-54°C to 49°C), the SF-ABC110ST remains operational in cold storage areas, northern climates, and hot vehicle interiors where standard extinguishers may fail. This broad range makes it suitable for year-round deployment without seasonal swaps.

Common Applications

Construction Job Site Trailers and Offices

Wall-mountable in site trailers, portable offices, and tool cribs to meet NFPA 10 requirements for Class A, B, and C coverage in occupied temporary structures.

Service and Work Vehicles

The standard vehicle/marine bracket and compact dimensions make the SF-ABC110ST ideal for mounting in trucks, vans, and service vehicles where space is at a premium.

Marine and Watercraft

U.S.C.G. approved (Type B:C Size I) for use aboard vessels, covering flammable liquid and electrical fire risks common in engine compartments and fuel storage areas.

Electrical Equipment Areas

The Class C rating makes it appropriate for placement near electrical panels, generator sets, and power distribution equipment on construction sites.

Flammable Liquid Storage and Fueling Areas
