The wall edge of a coving mitre is the edge that sits on the wall edge of the coving.
You should stand with the wall edge of the coving and coving mitre nearest to you when determining what mitre cut you need.
Locating notch
Locating notches are found on steel and plastic folded triangle cove mitres.
They are positioned at the corners of the wall edge and hold the cove mitre in place on the coving.
Crease
Only found on folded triangle cove mitres, the crease runs down the middle and marks the boundary between the right and left face.
Right face
On a folded triangle cove mitre with the wall edge closest to you, the right face is the surface to the right-hand side of the crease.
The right face is used to guide the saw when cutting a right-hand internal mitre or left-hand external mitre.
Internal mitre joints are the mitres needed to form the corners in a square or rectangular room. An external mitre joint is needed when when fitting coving around a wall that protrudes out into a room such as a chimney breast.
A right- or left-hand mitre is taken from the point of view of the coving, as if you were looking into the room from the outside, not from your viewpoint looking at the wall!
The waste coving that you discard after making a mitre cut with a cove mitre is usually larger when making external mitre cuts.
Left face
On a folded triangle cove mitre with the wall edge closest to you, the left face is the surface to the left-hand side of the crease.
The left face is used to guide the saw when cutting a left-hand internal mitre or right-hand external mitre.
The waste coving that you discard after making a mitre cut with a cove mitre will be larger when making external mitre cuts.
Hole
The hole found on some cove mitres serves no function in its use and is solely an aid for manufacturing purposes – although you might want to use it to hang the cove mitre on a hook.
