Spare Fire Sprinkler Cabinets

Spare fire sprinkler head box & cabinet

Keep your fire protection system compliant and ready for emergencies with a durable spare fire sprinkler head box, also known as a spare sprinkler cabinet, from QRFS. Designed for safe, organized sprinkler head storage, these boxes help you meet NFPA 25 and NFPA 13 spare-head requirements while protecting vital components from damage and corrosion. Whether you need a 3-, 6-, 12-, or 24-head cabinet, we carry multiple options to fit your system size, sprinkler types, and facility needs.

Sprinkler head storage for NFPA compliance

NFPA 25 and NFPA 13 require every fire sprinkler system to maintain a stock of spare sprinkler heads in a proper storage cabinet for quick replacement after sprinkler activation or damage. Commercial systems must keep at least six and up to a minimum of 24 spare sprinkler heads, depending on the system size, in a cabinet with the correct wrench for each sprinkler type installed. QRFS offers steel spare head boxes with a red finish and knockout-design shelves that enable storing various sprinkler sizes.

Durable fire sprinkler head cabinet construction

Each fire sprinkler head cabinet is constructed from high-quality steel with a powder-coated red finish for durability and easy visibility. The hinged door and sturdy construction protect sprinkler heads and wrenches from dust, moisture, and tampering.

Cabinets include slots for different fire sprinkler heads with knockouts that enable fitting multiple head sizes, plus specialty cabinets to ensure various sprinklers—whether 1/2 in. NPT, 3/4-in. NPT, 1-in. NPT, or ESFR—can be stored correctly. Mounting holes make wall or surface-mounting cabinets near your fire sprinkler system riser simple and easy.

Frequently Asked Questions

What is a fire sprinkler spare head cabinet used for?

A fire sprinkler spare head cabinet is used to store extra sprinkler heads and the proper wrench required for replacement. It ensures quick access to matching heads in the event of damage or activation, helping buildings stay compliant with NFPA standards and keeping systems operational.

Where should a fire sprinkler spare head cabinet be installed?

Fire sprinkler spare head cabinets are often installed near the system's main control valve and riser, though they can be placed in another accessible location. Regardless, cabinets must be located away from heat sources that could inadvertently activate or degrade the sprinklers. The cabinet must also be readily accessible for emergency replacement of operated or damaged heads.

How many spare fire sprinkler heads are required by NFPA 13?

NFPA 13 (and NFPA 25) requires at least six spare heads for systems with up to 300 sprinklers, 12 spare heads for systems with 300–1,000 sprinklers, and 24 spare heads for systems with more than 1,000 sprinklers. Within that total, the cabinet must have at least two spare sprinklers of each sprinkler type and temperature installed within the system. The only exception is that system owners don't need to keep spare dry sprinklers onsite if the dry sprinklers in the system have different, custom barrel lengths.

What is included in a compliant spare sprinkler head cabinet kit?

A compliant spare sprinkler head cabinet kit includes the required number of spare sprinkler heads, a sprinkler wrench approved for those models, a list of all the sprinklers in the cabinet, and (of course) a durable cabinet to protect and organize them.

What sizes are available for fire sprinkler spare head cabinets?

Spare sprinkler head cabinets at QRFS are available in sizes to hold three, six, 12, 24, and 36 heads, with some models specifically designed for ESFR heads. The correct size depends on the number of sprinklers in the system and the corresponding NFPA 13 and NFPA 25 spare head requirements.
