High Security Sally Port Gate Upgrade at Maplehurst Correctional Complex
Location: Milton, Ontario
Industry: Correctional / High-Security Infrastructure
The Challenge: Replacing an Outdated System in a High-Cycle Environment
Maplehurst Correctional Complex required an upgrade to a critical sally port access point—a high-security zone where gates operate continuously throughout the day for service and delivery vehicles.
The existing system had been in place for years and relied on an old gate design that no longer met modern operational expectations.
The facility needed a solution that could deliver:
- Higher security and improved locking performance
- Reliable operation in a high-cycle environment
- Faster serviceability and access to replacement parts
- A system designed for Canadian climate conditions
But replacing the gate wasn’t just about performance.
The Constraint: Limited Space, Maximum Opening
One of the most complex aspects of this project was the restricted installation space.
Unlike typical installations, the available area for the gate system was extremely limited:
- The gate structure had to fit within a tight footprint
- The system still needed to provide maximum possible opening width
- The gate tail required clearance behind the structure during operation
In fact, the opening required by the facility exceeded what standard configuration would normally allow.
This created a dual engineering challenge:
- Fit the system within the available space
- Maximize the clear opening without compromising functionality
Traditional systems would struggle to meet both requirements simultaneously.
The Solution: ARMA HSOS Gate
The team selected the ARMA High Security Overhead Slide Gate (HSOS) as a modern alternative to the old system.
The HSOS Gate provided:
- Canadian-made engineering optimized for local conditions
- Advanced locking and high-security performance
- Reliable operation for high-cycle use
- Fast access to replacement parts and serviceability
But the real advantage came from ARMA’s modular engineering approach.
Engineering Around Constraints
The HSOS Gate is designed with a modular beam system based on 2-foot increments, allowing flexibility in how the structure is configured.
This gave the engineering team the ability to:
- Adjust post placement within the beam structure
- Modify the standard layout to fit tight spatial constraints
- Optimize the gate configuration to maximize opening width
At Maplehurst, this flexibility was critical.
By adjusting the positioning of structural components, the team was able to:
✔ Fit the gate within the limited space
✔ Gain additional inches of opening width beyond standard configuration
✔ Maintain full structural integrity and performance
This level of adaptability would not be possible with traditional fixed-design systems.
The Result: Modern Security with Operational Confidence
By upgrading to the ARMA HSOS Gate, Maplehurst Correctional Complex achieved:
✔ A Canadian-engineered system built for long-term performance
✔ A modern, high-security access solution
✔ Reliable performance in a high-cycle environment
✔ Increased opening capacity within limited space
✔ Reduced dependency on legacy systems
✔ Faster serviceability and parts availability
The project successfully replaced an outdated solution with a system designed for today’s operational demands.
Strategic Impact
Correctional facilities require infrastructure that delivers:
- Security without compromise
- Reliability under constant use
- Flexibility to adapt to site constraints
- Fast recovery in case of service needs
The HSOS Gate provides all of these through modular engineering and precision design.
Key Takeaway
When space is limited and performance is critical, traditional systems create limitations.
The ARMA HSOS Gate demonstrates that with the right engineering approach, it is possible to:
- Fit within tight constraints
- Maximize operational performance
- Deliver long-term reliability
All while upgrading security to modern standards.
