The mighty structural frame coupling range from Window Widgets.
Multi-beam is a ring-beam to be fitted or retro-fitted to proprietary conservatory roof systems to increase strength, e.g. for bi-fold door openings.
Fits casements and VS Frames and is compatible with multiple roof systems. If you have a problem with an existing installation with ‘bounce’ you can retro-fit Multi-beam.
Other advantages include reduced sight-lines, increased head height, identical return sight-lines. and no need for add-ons above frames.
