What is required for a frame when using partial struts with drywall walls?

The requirement for a frame when using partial struts with drywall walls is that it must be self-supported. This means that the frame does not rely on any additional supports, such as brackets or fastenings to the floor or walls, to maintain its structural integrity. A self-supported frame is designed to stand robustly on its own, which is crucial in ensuring that it can adequately support the elevator door system without causing stress or damage to the surrounding drywall walls.

This approach is particularly important because drywall tends to be less robust than other wall materials. Therefore, a self-supported frame minimizes the risk of unsettling the wall structure, providing a stable installation for the elevator doors. This method helps maintain the intended function of the elevator entrance while ensuring a clean and finished appearance without additional clutter from hardware mounting on the walls.
