Blades shall be extruded aluminium, parallel in operation and linked to minimise noise. Blades are supported via injection moulded nylon 66 bearings to ensure smooth operation.

Blades are housed in a galvanised case and are offered in three options:
Flangefit, Framefit and Spigotfit.

Dampers are designed for vertical installation with a blade limiting angle where horizontal applications are required.
