Key specifications
Length: 300 mm
Size: large
Finish: white
Type: mechanical door stopper for garage doors
How to use
Position the stopper at the required location on the door edge or on the adjacent wall where the door should be restrained. Mark mounting points, drill appropriate holes and secure the stopper using suitable fasteners for the mounting surface. Check alignment by opening the door slowly to ensure the stopper engages at the intended travel limit and adjust position if necessary. Periodically inspect the stopper and fasteners for wear or loosening and tighten or replace as needed to maintain reliable operation.
Usage recommendations
Use corrosion-resistant fasteners appropriate to the wall or frame material and avoid excessive force when the door contacts the stopper. For doors with high closing speeds or heavy mass, consider supplementary damping or a secondary stop to reduce impact loads.
