M4 is a two-part, side-mounted, glass railing system. This system is designed to allow the glass to be mounted at the floor level, creating an unobstructed view from the inside. The M4 system adds modern and elegant look to any balcony, deck, or terrace.

Two-part track system allows for easy staging of the installation. The metal track can be installed on the fascia first making the installation faster. Glass can be simply loaded from the top.
