Counter Fire
Shutters
Clean, attractive fire-rated security for service counters, concessions, and pass-throughs. Compact 10" brackets on all sizes. Single-technician drop testing. Built in Canada by SDI.

Fire Rated
Code-Compliant Protection
Purpose-built fire-rated counter shutters that meet building code requirements for fire separation at service counters and pass-throughs.
Compact
10" Brackets All Sizes
Compact 10″ brackets on all door sizes — ideal for minimal headroom applications where space above the opening is limited.
Easy Testing
Single Technician
Drop test can be performed by a single technician. Resets from one side of the opening, reducing testing time and costs.
Built for Security
Every SDI counter fire shutter is engineered with premium components for reliable fire protection and daily operation.
Rugged 2" Flat Slats
22 ga. steel slats provide a clean, attractive appearance with the strength needed for daily commercial use.
Corrosion Resistant Finish
Available in grey prime finish or galvanized steel — both options resist corrosion and look professional.
High Cycle Springs
Oil tempered torsion springs engineered for high cycle life — reliable performance across thousands of operations.
Mechanical Governor
Compact mechanical governor controls automatic closing speed between 6" and 2' per second for smooth, safe operation.
Fuse Link Release
Fuse link release device available for automatic fire response — the shutter closes when ambient temperature exceeds the rated threshold.
Compact 10" Brackets
All door sizes use compact 10″ brackets — minimizing headroom requirements and simplifying installation in tight spaces.
Mounting Options
SDI counter fire shutters are available in two mounting configurations to suit your building structure and opening requirements.
Face of Wall
Door mounts to the exterior face of the wall. Maximizes clear opening width. Standard for most counter applications.
Model: FPCF
Between Jamb
Door fits between the jambs of the opening. Clean, concealed appearance — ideal when exterior mounting isn't possible.
