Dear HBS Partners,

Through the ongoing development of the Window Wall system, we have improved the door rebate profile to enable easier manufacture and assembly.


The door frame is utilized as before but can now be retro-fitted into the frame once the main frame is installed on site. The AB210 sub cill can now run continuously under the door cill with the upstand trimmed down for the width of the door, to accommodate floor finishes.


Look out for further information on future Technical Bulletins with regards to the development of the Window
Sash and related hardware which will be circulated soon.

Please contact your nearest HBS Aluminum Systems Branch for more information or visit our website www.hbs.co.za
