The GL3 Channel Connector is for use with GypLyner Universal Metal Wall Partitioning Systems. The Channel Connector is used to fix together sections of the GL1 Lining Channels. It is made from a lightweight material that allows for a strong friction fit. To fix your GL1 Lining Channels to concrete walls and ceilings, use GL2 or GL9 Metal Fixing Brackets. They are made using flexible galvanized steel which enables them to encase the channels for a firmer hold.
