Flue Keeper™
The Original Flue Keeper™ was designed to keep boxes from encroaching into the transverse flue space in order to improve sprinkler penetration to products within the pallet rack structure.
These pallet safety stops meet NFPA standards and all fire codes in the US. The easy to use brackets allow for quick and effortless installation of racking flue space keepers. US Patent #7,857,152.
Benefits:
- Ensures optimal sprinkler system performance
- Provides 3″ flue space on each side of the rack post (6″ total)
- Heavy-duty tube members for up to 48″ frames (custom sizes available)
- Flue keepers act as pallet safety stops at various elevations
- Versatile flue space keepers for pallet or product levels
- Complies with insurance and building code requirements (including International Fire Code 2012)
- Compatible connectors for all major rack brands

Transverse Flue Space Flue Keeper
What are pallet rack flue spaces?
A pallet rack flue spacer, similar to a fireplace flue, creates a vertical space for fire, heat, and smoke to rise through a pallet rack. These spaces allow a clear line of sight from the floor to the ceiling.
Open flue spaces enable heat and smoke to activate fire sprinklers, allowing water to reach all levels of stored products and extinguish fires effectively.
Blocked flue spaces can cause fires to spread horizontally, increasing damage. Keeping these spaces clear with pallet rack spacers improves fire detection and suppression, reducing the spread of fire.
An open flue space provides for heat and smoke to rise in the event of a fire triggering fire suppression sprinklers. This type of warehouse rack spacing also allows for the water to penetrate the multiple levels of stored product to extinguish the fire at its source.
What types of flue spaces are in pallet rack spacing products?
Longitudinal Flue space is the clearing or spacing between back-to-back rows of pallet rack. In other words, the longitudinal flue space is the space or distance between two back-to-back rows of pallet rack. Typically, pallets are loaded too far back on the rack in both back-to-back rows or product becomes dislodged which blocks the flue. With proper warehouse rack spacing and flue protection this can be avoided.
Transverse Flue spaces are known as the space or gaps between the pallet load and the upright frame of the rack. Typically, if pallets or boxes are stacked less than 6″ from other pallets they are blocking the transverse flue space. This pallet rack flue spacer’s upright frame is not considered as open or part of the flue, and therefore requires 3” of open space on both sides of the frame.
