Rail for garage door opener Hormann FS-2 two-piece M for Promatic/Supramatic (MPN 435571)

Replacement two-piece FS-2 rail by Hormann, size M, designed for use with Promatic and Supramatic garage door operators. This rail assembly connects the opener drive unit to the door carriage and provides the structural guide for smooth, reliable transmission of motion. It is intended as a direct replacement or spare part for compatible Hormann models and is suitable for repair, maintenance or upgrade work on sectional garage doors.

Advantages

The two-piece construction simplifies transport and installation in constrained spaces while maintaining the required rigidity and alignment for normal garage door operation. Manufactured to Hormann quality standards, the rail provides consistent fit and function with Promatic and Supramatic operators. The M size offers a balance between compact footprint and stroke capability, making it appropriate for standard door heights and typical domestic installations.

Suitable for

• Owners of sectional garage doors using Hormann Promatic or Supramatic operators
• Repair technicians replacing worn or damaged rails
• Maintenance jobs requiring original-equipment replacement parts
• Upgrades where the existing rail is incompatible or degraded

When it may not be suitable

This FS-2 two-piece rail in M size may not be suitable for non-Hormann opener systems or for installations that require a different rail length or profile. It is intended for compatible Promatic and Supramatic units; using it with other brands or non-matching models could result in improper fit or impaired operation. For very tall doors, heavy-duty or commercial applications a different rail size or a single-piece heavy-duty rail may be required.

How to use

Install the rail according to the operator manufacturer’s instructions: secure the two rail sections together and mount the assembled rail to the operator drive unit and the garage ceiling or support bracket, ensuring correct alignment with the door carriage and track.
