Special-Lite Expands SpecSlide Commercial Sliding Door System with New Configurations and Performance Options
Key Takeaways
- New bi-parting sliding door options: SpecSlide is now available in independent and synchronous bi-parting configurations for paired-door and wider openings.
- Self-closing operation: A mechanical self-closing option is available for single-slide configurations.
- Smoke-control option: A UL 1784 smoke-control configuration with an S label is available for single-slide configurations.
Special-Lite has expanded its SpecSlide® Surface-Mounted Sliding Door System with new bi-parting configurations, self-closing operation and a UL 1784 smoke-control option. These additions enhance how our sliding door solution can be incorporated into various commercial interior openings and projects.
“Expanding SpecSlide gives architects and specifiers greater flexibility across a wider range of openings and performance needs,” said Alex Esposito, President and COO of Special-Lite. “These new options build on the space-saving design, smooth operation and easy installation SpecSlide has provided since it debuted.”
Designed to maximize usable space without sacrificing aesthetics or durability, SpecSlide brings smooth, space-saving operation and simplified installation to offices, consultation rooms, hallways and other commercial interiors.
SpecSlide has been tested to more than 300,000 cycles and features exclusive Hawa SoftMove sliding door hardware for smooth operation. The system pairs with a range of Special-Lite door options, sidelites, hardware and finishes, allowing architects and designers to customize a solution that fits both the performance and aesthetic needs of various spaces. SpecSlide launched in 2024.

What New Configurations Are Available for SpecSlide?
Special-Lite has added Independent Bi-Parting and Synchronous Bi-Parting configurations to expand the types and sizes of openings SpecSlide can accommodate.
With the Independent bi-parting configuration, two sliding door leaves operate independently, allowing either side of the opening to be opened or closed separately.
With synchronous bi-parting, both leaves move together using a belt-driven system for coordinated opening and closing. The configuration provides the benefits of a paired sliding door system with synchronized operation.
Together, the new configurations make SpecSlide an option for a broader range of commercial interior applications, including wider openings and designs that call for paired sliding doors.
Greater Flexibility for Commercial Interior Sliding Doors
With the addition of bi-parting, self-closing and smoke-control configurations, SpecSlide can solve a broader range of commercial interior opening challenges while maintaining the space-saving advantages and easy installation this surface-mounted sliding door system offers.
Architects, designers and specifiers now have additional flexibility for wider openings, paired-door designs, self-closing applications and openings requiring a smoke-control rating.
SpecSlide can also be coordinated with Special-Lite’s interior entrance and aluminum framing products to create cohesive interior opening systems.

Yes. A mechanical self-closing option is now available for single-slide SpecSlide configurations.
The addition allows the sliding door to close automatically after use, expanding the system’s capabilities for commercial interior openings where self-closing operation is desired or required.
Yes. SpecSlide is now available in a UL 1784 smoke-control configuration with an S label for single-slide applications.
UL 1784 addresses air leakage through door assemblies and other opening protectives used for smoke control. The new configuration expands the range of performance requirements that the SpecSlide system can address.
SpecSlide continues to offer Hawa SoftMove 100 triggerless soft-open/soft-close hardware, providing smooth, cushioned operation without requiring a separate trigger mechanism.
Closing-assistance and concealed-seal options vary by configuration. Concealed lift or drop seals are available for applicable configurations to support project-specific opening requirements.
