Key benefits
Improved Fire Protection
Flue space dividers let heat escape to sprinklers for quicker activation and let water reach lower inventory levels. Fire spreads vertically through the flue space instead of horizontally to other racks and product.
Optimal Pallet Placement
Maintains even offsets and centers loads on beams. Prevents pallet push-through and reduces the risk of injury or death from falling objects.
Minimizes Product Damage
Flue Guard only has contact with the pallet, not the stored products, significantly minimizing damage.
Easy Installation & Compatibility
Installs on new or retrofitted pallet rack systems, attaching with included high-strength tek screws for a quick, seamless install. Compatible with wire decking up to 2-gauge wire diameter.
Patented, Strong & Cost-Effective
A patented design built to hold the longitudinal flue space open under load, an essential addition to any warehouse rack system.

Sizes here are the double-stop unit, at a 5″ stop height in standard gray powder coat, shipping with the tek screws for install. The single-stop unit is listed separately as Flue Guard™ – Single Sided, and any other flue width is made to order in the configurator below.

How Flue Guard works ›Related products
The single-stop version of Flue Guard™. It mounts on one pallet rack beam instead of spanning a back-to-back pair, and stops pallets before they can be pushed through into the flue space. Stocked with a 3″ base flange in standard gray powder coat.
- Configuration: Single stop, mounts on one beam
- Stock size: 3″ base flange
The original transverse flue space keeper, designed to keep boxes from encroaching into the transverse flue space so sprinkler water can penetrate the pallet rack. The brackets also act as pallet safety stops at various elevations and install quickly on all major rack brands (US Patent #7,857,152).
- Standard size: 42″ × 3″
- Flue space: 3″ on each side of the post (6″ total)
- Members: Heavy-duty tube for frames up to 48″ (custom available)
- Function: Pallet safety stop at pallet or product levels
The heavy-duty version of the back-to-back Flue Guard™: the same double stop that holds the longitudinal flue open between rows, with an angle-iron brace along the bottom for heavier pallet loads than the standard stop is built for. Made to order to your flue width and beam.
- Configuration: Double stop, spans a back-to-back pair of beams
- Reinforcement: Angle-iron brace along the bottom
- Sizing: Made to order to your flue width and row spacer
