Warehouse Fire Protection & Safety
At Total Warehouse, we specialize in helping warehouses maintain proper flue space in back-to-back pallet racking systems. Maintaining a clear 6" longitudinal and 3" transverse flue space is not just best practice—it’s required for fire safety, sprinkler performance, and code compliance. We provide everything you need to meet these standards, from planning and layout to the right hardware and installation.

Protecting Your Investment
Safeguard Your Infrastructure
Our customized storage systems do more than just maximize capacity — they protect your people, products, and property. Our solutions prioritize safety, fire code compliance, and operational efficiency.
A key part of this is flue space — the vertical gaps between and within rack rows that let heat rise and sprinklers work effectively during a fire. Both transverse (between pallets and uprights) and longitudinal (between back-to-back rows) flue spaces are essential for NFPA compliance and warehouse safety.
What is Flue Space?
High-Impact Zone Protection
Flue space is essential for warehouse fire safety and NFPA compliance. These vertical gaps let heat rise so sprinklers can activate quickly and contain fires. There are 2 key types:
- Transverse – between pallets and uprights in a rack row
- Longitudinal – between back-to-back rack rows
Protect your people, inventory, and facility. We design racking systems with proper flue spacing to keep your operations safe, compliant, and efficient.
Flue Space Products
Preserve Flue Space. Stay Compliant.
Keep pallets in place — and your fire safety intact. Pallet Load Stops mount directly to the beam, creating a reliable barrier that prevents pallets from being pushed too deep into back-to-back rack bays.
Ensure code compliance, sprinkler performance, and operational control.
- Precision Depth Control: Maintains the required 6″ longitudinal flue space
- Bolt-On Design: Fast, secure installation on most rack beams
- Built-In Fire Safety: Reduces risk of flue space violations that hinder sprinkler function
Protect Rear Flue Space. Support Fire Safety.
Flue Guards are a simple, effective solution for keeping pallets out of rear flue zones — helping maintain proper airflow and ensuring clear access for fire suppression systems.
These guards clip directly onto wire decking, making installation fast and tool-free, while their wraparound design stops accidental overhang before it becomes a safety issue.
- Wraparound Protection: Prevents pallets from breaching flue space
- Fast Clip-On Install: Attaches easily to most wire decks
- Sprinkler Safe: Maintains rear clearance for fire system performance
Ensure Rack Alignment. Preserve Flue Space.
Row Spacers connect back-to-back racking rows to maintain consistent, code-compliant spacing. They help preserve the 6″ longitudinal flue space required for fire safety, while also reinforcing structural stability across your system.
Built for reliability, they prevent rack shift, misalignment, and costly code violations.
- Flue Space Assurance: Maintains 6″ clearance between rows
- Rigid Support: Keeps racking rows aligned and secure
- NFPA-Compliant: Helps meet fire code and safety standards
Lock In Transverse Flue Space. Improve Fire Safety.
Flue Keepers mount between rack beams to maintain uniform spacing between side-by-side pallets, preserving critical transverse flue space for proper fire suppression. Protect your aisle-to-aisle clearance and stay fire-code ready.
Built from durable steel, they withstand repeated contact and ensure your racking stays safe, consistent, and code-compliant.
- 3″ Flue Gap Control: Enforces consistent transverse spacing
- Heavy-Duty Construction: Withstands pallet impact and daily use
- Easy Installation: Mounts directly to rack frames with no hassle
Simple. Visible. Code-Compliant.
Keep Clear Labels provide a bold visual reminder to maintain 3″ flue spacing—helping your team stay alert, aligned, and compliant at every rack level.
With fast application and long-lasting durability, they’re an easy way to reinforce warehouse safety without slowing down operations. Promote safer habits and protect critical flue space.
- High-Visibility Design: Clear messaging improves operator awareness
- Quick Installation: Apply with adhesive or magnets in seconds
- Warehouse-Ready: Durable material resists wear, dust, and impact
Guide Pallet Placement. Protect Flue Space.
Snap-On Dividers clip directly onto wire decking to create clear, visible boundaries between pallet positions, helping operators consistently maintain 3″ transverse flue spacing.
Fast to install and easy to use, they’re a simple solution for improving placement accuracy and supporting fire code compliance.
- Visual Placement Guide: Defines pallet zones to enforce spacing
- No Tools Needed: Snaps onto wire decking in seconds
- Operator-Friendly Design: Reduces errors and overhang risks
Block Push-Through. Protect Rear Flue Space.
Stop Beams serve as solid physical barriers to prevent pallets from being pushed too far into back-to-back racks—helping preserve 6–12″ of critical rear flue space and reduce fire hazards.
Ideal for boosting both warehouse safety and sprinkler system performance. Reinforce safety and spacing at the rear of every bay.
- Adjustable Mounting: Installs above rear beam at 6″–12″ depth
- Pallet Impact Protection: Stops over-insertion before it becomes a risk
- Fire-Ready Clearance: Maintains open paths for sprinkler activation
Pallet Protector
Prevent Damage
Pallet racking protection is an important consideration for any business which operates a racking storage solution. Without adequate pallet racking protection, you risk costly and potentially damage occurring, putting workers at risk and increasing the possibility that goods will be destroyed.
