Single Disc - MB75 Glass Balustrade System

Product Description

The Single Disc MB75 was born from testing and modeling 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 or steel profiles.
