The Hörmann Garage Door Roller Holder #4 (part number 18001009) is a genuine OEM roller bracket designed for select Hörmann sectional garage doors. Identified as “No. 4,” this carrier mounts at the designated fourth panel position to secure the door’s track roller, keeping the door sections aligned and moving smoothly within the side tracks. It serves as a direct replacement for worn or damaged hardware, restoring proper travel, reducing vibration, and helping maintain quiet, reliable operation on residential or light commercial Hörmann sectional door systems.
This component is intended for Hörmann doors that use numbered hinge/roller carriers; it is not universal and should match the exact part number and position specified in the door’s parts list. Installation generally follows the existing mounting pattern on the door section; ensure the door is secured and the opener is disconnected before service. Always follow the official Hörmann service documentation for your specific model, and consult a qualified technician for any adjustments related to balance or spring tension. Verifying the stamp/marking on your current bracket or referencing the Hörmann parts diagram for your door model is recommended to confirm compatibility with 18001009.
