Do I have to glue to the frame mitres?

You don’t have to glue the mitres, but you get a better, tighter frame if you do.

The mitre corner connecter will hold the mitres together without glue. There is a small protruding lug on the connector that clips into the side of the frame to hold in place.

We recommend gluing the mitres when you are side fixing as this helps keep the mitres together when screwing sideways.
