The Dorma RTS85 Side Load Closer Arm and Channel is a critical component for the installation of RTS85 concealed transom closers. This side load assembly is designed to provide a secure mechanical connection between the closer mechanism and the door leaf, allowing for smooth and controlled operation.

This hardware is commonly utilised in commercial door systems where a concealed closing solution is preferred for aesthetic or functional reasons. The side load design is particularly advantageous as it allows the door to be offered up to the transom closer and secured laterally, which can simplify the installation process in restricted spaces.

Typical applications include aluminium shopfront doors and timber commercial doors. For successful installation, the door's top rail must accommodate the guide channel, requiring a minimum width of 38mm and a depth of 15mm. As a genuine Dorma accessory, this arm and channel set ensures full compatibility and long-term reliability within the RTS85 system.

FAQs

This Dorma 8530 arm assembly is designed for installation within top rails that have a minimum channel depth of 15mm and a width of 38mm.

This arm and channel set is specifically engineered for use with the Dorma RTS85 series of overhead concealed door closers.

Side load refers to the installation style where the arm is fitted into the channel from the side. This is often preferred for specific door and frame configurations where vertical loading is restricted.

This set includes both the main closer arm and the corresponding mounting channel. The channel features pre-drilled countersunk holes for secure fixing to the door rail.
