The Dorma RTS85 Floor Pivot Set is a critical hardware component designed to work in conjunction with the RTS85 overhead transom closer system. This set provides the necessary lower pivot point for the door leaf, ensuring smooth, controlled, and reliable rotation in high-traffic commercial environments.

The set is highly versatile, containing both the 8852 and 8853 floor portions to accommodate various door rail specifications. The 8852 component is specifically engineered for bottom rails with a channel depth of 18mm to 20mm. For deeper profiles, the 8853 component supports channel depths from 18mm up to 50mm and can be shortened as required to fit specific rail dimensions. This flexibility makes it an ideal solution for both new installations and replacement scenarios.

Typical applications include glass or metal framed doors where concealed door control is required, such as in shopfronts or office buildings. The floor portion is fixed directly to the floor surface, providing a robust base for the end-load arm assembly. By using this genuine Dorma set, installers ensure system compatibility and long-term durability for the entire door opening.
