Galaxy Nickel Corner Molding Cabinets

Start by ruling one thing out, because it is where half the confusion comes from. The inside angle of an L-shaped run — where two banks of cabinets meet in a corner — is not a corner-moulding problem. That is resolved by a corner cabinet, a blind cabinet or a filler, and it is a layout decision made long before trim. The corners on this page are the ones where a visible finished surface changes direction.

• The end of an island, where a finished end panel meets the finished back panel. The most common of the four by a wide margin, and the one at seated eye level.
• A peninsula, same joint, but on two corners instead of one and usually with a counter overhang above it.
• A tall cabinet that projects forward of the run, where its 24-inch-deep side meets the face of the 12-inch-deep cabinets beside it.
• A hood surround or a built-out chimney, where the cladding turns at both front corners — often the only place in a kitchen with two outside corners within four feet.

An outside corner is where the two best-lit faces of a run meet, and on a mid-tone finish the two planes take light quite differently from each other — one catches the window, one falls into shade. A seam at exactly that line is more legible here than the same seam in white, where both faces read as near-white regardless of angle. That is the one reason the colour changes this decision at all, and it argues for covering an island corner rather than trusting the joint.

Three parts are stocked and the naming is literal. GN ICM8 at $59.80 is inside corner moulding, for a re-entrant angle — the joint sits in the crook, and the moulding fills the internal angle between two surfaces. GN OCM8 at $62.40 is the outside version, sitting over a projecting corner like a cap over the edge. Both come as eight-foot lengths, which the 8 in the code tells you.

The third part, GN OCM8-1 1/4″ at $78.00, is the same outside profile in a larger section. That extra quarter of material buys coverage: where a corner is made of thicker panels, or where the two surfaces are not perfectly flush and the seam is wider than a thin moulding will bridge, the bigger profile covers it. It is $15.60 more than the standard one and it is worth having on an island where the panels have been handled and the corner is not immaculate.

For context on where these sit against the other joint-closing parts: a scribe meets an irregular wall, a quarter round bridges a gap at the floor, a filler closes a constant space, and corner moulding covers a manufactured joint between two finished pieces. Four different problems, four different parts, and they are substituted for one another on site more often than any of us would like.

The panels are finished on their faces to a high standard, and they are cut square. So why does the corner not simply disappear? Three reasons, all of them mundane.

First, the corner is never a perfect arris. Two pieces of half-inch or three-quarter-inch material meeting at ninety degrees leave an edge, and the finish on that edge is thinner than on the flat by the nature of how finish is applied. In raking light — which is exactly what an island corner gets from a window — that edge reads as a line.

Second, the joint moves. A house takes on moisture in summer and loses it in winter, and the two panels move independently. A joint that is closed on installation day in June can show a hairline in February. That is normal timber behaviour rather than a defect, and covering the joint is how it is dealt with.

Third, and most practically: corners get hit. An island end is at hip height in a walkway and takes trolleys, chairs, bags and people. A moulding over it is a sacrificial part that costs $62.40 to replace, which the panel underneath is not — an argument that has nothing to do with appearance and is frequently the better one.

The arithmetic here is unusually friendly, because corners are vertical and vertical dimensions in a kitchen are short. An eight-foot stick is ninety-six inches. A base cabinet corner is about thirty-four and a half inches tall, so one stick yields two base corners with more than two feet left over. A tall cabinet corner at ninety-six inches uses a whole stick exactly and leaves nothing, which is worth knowing before somebody plans to get a second corner out of it.

Two practical notes on top of the table. Cut every corner from a single length rather than joining — a butt joint in a vertical corner moulding is more visible than the seam it was covering. And where an island has a raised bar top, the corner is taller than the cabinet, so measure the finished height of the panel rather than the height of the box. The island clearance guide has the dimensions those two configurations actually come out at.

A corner that wants presence rather than covering is a post job, not a trim job. GN CP36 corner post is $312.00, and it turns the corner of an island into a furniture element — a column of material with its own profile — rather than a covered joint. That is five times the price of the moulding and it is a different intention entirely. The pilaster and post page is where those live.

A corner nobody can see does not need covering. The back corner of a peninsula against a wall, or the corner of a tall cabinet in a pantry alcove, can be left as a butt joint without consequence. Mark the corners on the plan that are actually in a sightline and order for those.

And a corner where the two surfaces are not the same finish is a different problem. On a two-tone plan where an island in a second colour meets a perimeter run, the corner trim has to belong to one of them, and covering the joint draws attention to the change rather than hiding it. In that situation a clean butt joint, or a post in one of the two colours, is the sounder answer — the Fabuwood colour range shows what the second run is usually paired with.
