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 (subject to detail in Annex B5 of the ETA). EGCM can be surface mounted or recess fitted. A routing template is available separately.

Material

Joist plate: 16mm aluminium
Header plate: 16mm aluminium

Features

Concealed connection
Provides up to 30 mins fire resistance
Can be routed for flush installation, or surface mounted
Can be pre-installed off-site for rapid assembly
Each component easy to pair due to identical width and height
Light weight aluminium for ease of handling

Application

Suitable For

Solid timber
Glulam

Use With

Timber to timber connections as part of single or multi-storey construction projects

Installation

Mounting connectors EGCM is simplified by the use of a jig available on stock.
The slot can be routed by using a Ø16mm cutter with Ø30mm washer.
CAUTION: EGCM should not be used for an assembly with a negative slope.
