FAQ — Frequently asked questions about the 20 lb surface cabinet

What is the difference between a surface-mounted cabinet and a recessed cabinet for a 20 lb fire extinguisher?

A surface-mounted cabinet fixes directly to the wall and projects outwards, making its installation very simple and fast. Due to the significant size of a 20 lb fire extinguisher, recessed or semi-recessed models require a deep opening cut inside the wall to reduce the projection into corridors or high-traffic walkways.

Can this steel cabinet be installed in an outdoor environment?

This steel cabinet is designed for indoor use or in locations well-sheltered from weather elements. For direct exposure to rain, snow, or high moisture, it is strongly recommended to use weatherproof fiberglass or thermoplastic cabinets to prevent the steel from rusting.

How do you open the cabinet to access the extinguisher during a fire?

The cabinet typically opens using a standard handle latch for immediate access. On certain high-security or anti-tamper models, access requires breaking the glass panel or clear access window using a small emergency hammer mounted nearby.
