SingleDisc MB75

Glass Balustrade System


The SingleDisc MB75 is a side fixed frameless glass balustrade system 


The SingleDisc MB75 was born from testing and modelling balustrade fixings to determine the optimum economical fitting for clamp fixing balustrades.

The outer disc was profiled to give an attractive appearance and the single fixing point means it can be located on the edge of narrow concrete slabs, steel or timber profiles.


The SingleDisc MB75 is 75mm diameter. The inner spacer is 30mm thick and the outer plate 10mm thick.


Material & Finish

The SingleDisc MB75 is made from 316 grade stainless steel and is available in machine satin or polished finish.
