EGCM

End Grain Connector (Medium Duty)

Suitable for solid timber and Glulam joists: EGCM is a two-piece system that provides a high-strength, hidden connection between timber members where the joist header or post is fastened into the end-grain of a carried joist.

As the connector is concealed within the timbers, this method provides 30 minutes fire resistance. EGCM can be surface mounted or recess fitted. A routing template is available separately.
