The Alumasc Skyline Aluminium Column Casing Universal Flat Extender Panels are designed to work with the main Skyline column casing system, enabling the creation of elongated columns and striking wall features.

Supplied in 3m standard lengths, with sizes ranging from 500mm to 1000mm, each extender panel integrates effortlessly with the casing system to achieve additional height or feature detailing. Panels are supplied in a single unicolour finish as standard, with dual-colour options available on request at additional cost.
