Galaxy Nickel Corner Post Cabinets

An outside corner happens wherever cabinetry turns out into the room rather than into a wall. The end of an island. The end of a peninsula. A run that comes off a wall and stops. A tall cabinet standing proud of the run beside it. In each case two finished faces arrive at the same ninety-degree line, and something has to happen at that line.

Three honest outcomes. A mitre, both faces cut at forty-five degrees and meeting in a point — clean, expensive in labour, and unforgiving of a wall that is not plumb, because the joint opens along its length if anything is out. A butt joint, one face running past the other, leaving a visible edge of core down the corner. Or something applied over the top, which hides the joint and any discrepancy behind it, and is why every part in the next table exists.

That reframes the purchase. None of these parts is decoration in the first instance; they are all covering a joint, and they differ only in how much they want to be noticed while doing it.

The ladder is not a quality ladder. The $62.40 moulding covers the joint as completely as the $312.00 post does, and on a corner nobody looks at it is the better purchase by a factor of five. What the money buys as you climb is presence: the moulding hides a problem, the heavier profile turns it into a line, the overlay filler turns it into a deliberate break, and the post turns it into an object.

Note also that the mouldings are sold by the eight-foot stick and the post is sold as a single 36-inch part. A stick of GN OCM8 covers a 36-inch base corner twice over with offcut to spare, so on a kitchen with two or three outside corners the moulding route is cheaper still. Quantities and the ten-to-fifteen per cent waste rule are on the decorative accessories page.

This is the part of the job that decides whether the corner looks right, and it happens entirely on site. Cabinet runs are installed to a level line in rooms that are neither level nor plumb. A vertical part fixed straight to an out-of-square corner opens a tapered gap down one edge, and a tapered gap is far more visible than a parallel one, because the eye reads the taper as a mistake rather than as a tolerance.

The fix is a scribe. The installer holds the part in position, sets a compass to the widest point of the gap, and runs it down the length so the pencil traces the real shape of the wall onto the back edge. That line is then cut to — a block plane on a small discrepancy, a belt sander on a larger one — and the part goes on tight down its whole length.

Two rules follow, and they are worth passing to whoever is fitting. The scribe comes off the hidden edge, never a visible face: sanding through finish on a back edge is invisible and normal, and on a face that shows it is a replacement part. And the part has to be ordered long enough to scribe, which is another argument for the eight-foot moulding over a part cut to a fixed height. The difference between a scribe, a filler and a panel is in end panels, scribe moulding and fillers explained.

One note that belongs to this finish. On a mid-tone, the shadow inside an eighth-inch gap is only slightly darker than the face beside it, so the eye registers the line rather than the depth — it reads as a scratch rather than as a shadow. Which means a corner fitted tight looks noticeably more expensive here than one fitted nearly tight.

The post earns its price in a small number of specific positions, and pretending otherwise would be doing you a disservice on a $312.00 part.

• Buy it where the corner is a terminus the room looks at. The end of an island the dining table faces, the outside corner of a tall run at the entrance to the kitchen, the corner where a peninsula meets an open-plan living space. In those positions the corner is already a focal point and the post confirms it.
• Buy it where a vertical already exists elsewhere and needs answering. If there is a pilaster or a column somewhere in the room, a bare mitred corner across from it looks unfinished in a way it would not have done on its own.
• Do not buy it for a corner behind the refrigerator, beside a door swing, or at the back of a galley — corners exist in plans that nobody stands in front of, and they take the $62.40 moulding.
• Do not buy it in a narrow galley at all. A post projecting into a walkway that is already tight is the wrong trade: in a room under about ten feet wide, the moulding covers the joint without costing an inch of the lane. Small kitchen layouts has the clearances.
• Do not buy it where the corner is against a wall rather than open to the room — that is an inside corner, and it takes GN ICM8 at $59.80 or a scribe moulding at $39.00, not any of the parts on this page.

GN CP36 comes in a single size, and 36 inches is not an accident: a base box is 34½ inches and a standard counter finishes at 36, so this part is dimensioned for a base or island corner and nothing else. There is no 30-inch version for an upper run and no 96-inch version for a tall one, so if your outside corner is somewhere other than base height, the answer is on a different page.

For an outside corner on an upper run, the wall pilasters cover 30, 36, 39 and 42 inches at $201.50 to $243.75 — applied rather than wrapped, but at eye level a run stopping with a finished vertical reads the same way. For a tall run, the tall pantry pilasters run 84 to 96 inches at $455.00 to $464.75, or a 96-inch column at $624.00 if the corner is meant to be architecture. And at any height at all, the corner moulding is eight feet long, which is the real reason it turns up on so many quotes: one stick covers a base corner, an upper corner and most of a tall one.

Whatever the height, order the finished side that goes with it. A corner is two faces, and covering the joint does nothing for a cabinet side that was never finished in the first place — the end skins are $50.05 on any wall height, $62.40 at base and $169.00 on a tall cabinet.

Walk the plan and mark every point where cabinetry turns out into the room — not where it turns into a wall, which is the other condition and takes different parts. For each mark, ask the only question that matters: does anyone stand and look at this corner? The ones that get looked at can have the post. The rest take a stick of moulding, and one eight-foot stick usually covers two or three of them. Then add the finished sides, confirm who is scribing, and order it all with the cabinets so the trim comes off the same finish batch.

The whole trim list including mouldings, skins and fillers is on the decorative accessories page, the loose parts list carries the small finished pieces, and the finish sits on the collection page. Builders and remodelers order through Captivating Pro.
