Converting a distribution box into a fire extinguisher box typically costs between $100 and $400, depending on materials, size, and installation requirements.

Cost Factors

1. Materials and Design Fire extinguisher boxes are usually made from metal or shatterproof polyethylene, designed to protect the extinguisher from impact, weather, and tampering while keeping it visible and accessible . If your distribution box is metal, modifications may include adding internal straps, clear inspection panels, and a weatherproof seal, which can increase costs .
2. Size and Capacity The cost depends on whether the box will house a single extinguisher (9–12 kg) or multiple units. Single cabinets are generally less expensive, while double or larger cabinets with reinforced doors and inspection panels can cost more .
3. Installation Professional installation of a fire extinguisher cabinet ranges from $75 to $250 per unit, depending on wall type and location . If the conversion is done in-house, you can save on labor costs, but you may need to ensure proper mounting and compliance with safety standards.
4. Additional Features Adding locks, alarms, or custom labeling can further increase the price. Cabinets with clear panels for inspection or weatherproof seals are slightly more expensive but improve safety and compliance .

Estimated Conversion Cost

• Basic conversion (single extinguisher, minimal modifications): $100–$150
• Moderate conversion (internal straps, clear panel, weatherproofing): $150–$250
• High-end conversion (double extinguisher, reinforced door, alarm, professional installation): $250–$400

Recommendations

• Ensure the converted box meets local fire safety regulations.
• Use durable materials to protect the extinguisher from environmental damage.
• Consider professional installation if the box will be mounted in a high-traffic or outdoor area. By evaluating the size, materials, and installation needs, you can select a cost-effective solution that ensures both safety and compliance .
