Forty-two inches: the blind corner grows a pull-out, and it is handed
Reviewed September 2026 · Captivating Cabinets
Three part numbers are made this wide and one of them changes what the width is for. GN BLB42/45 is the first blind corner the accessory board actually supports: a pull-out unit exists for it, in a left hand and a right hand, and it costs $510.25 more than the cabinet. Everything else up here is doors, and doors are a geometry problem rather than a shopping one.
Three boxes, and what is no longer made
Forty-two is where the board thins out to almost nothing.
| Part number or family | Displayed price | Notes |

| GN SB42 | $572.00 | The widest sink base made |
| GN B42 | $757.25 | Standard base, drawers over doors |
| GN BLB42/45 | $767.00 | Blind corner, reaching 42 or 45 inches |
| Full-height door base | not made | The FD family ends at 39 inches |
| Drawer bank | not made | Ends at 36 inches |
| Apron sink, corner storage | not made | Both end at 36 inches |
| 12-inch-deep base | not made | Ends at 36 inches |
Handed hardware, and the order it forces
The blind-corner pull-outs are GNK BPO-BLB42/45-L and GNK BPO-BLB42/45-R, both $1,277.25. The suffix is not a preference — it is the side the blind end of the cabinet faces, which is fixed by which wall the corner turns into, which is fixed by the layout. One of the two is correct and the other is a return.
That forces an order of operations most people get backwards. The corner is decided first: which leg is blind, how far the box is pulled from the corner, and therefore which hand the hardware is. Only then are the two runs either side laid out, because the blind end is what they both start from. Draw the runs first and you will find yourself choosing between moving a sink and re-ordering a $1,277.25 pull-out.
The money is worth stating plainly too. Cabinet $767.00 plus hardware $1,277.25 is $2,044.25 for one corner — two and two-thirds times the box. That is the price of turning a blind cavity into something you can reach, and it is the reason a great many kitchens have a blind corner full of things nobody has seen for four years. Decide which of those two you are buying.
Forty-two inches of doors is twenty-one inches of swing
GN B42 at $757.25 takes two doors, so each one is around twenty-one inches wide. Full-overlay doors on concealed hinges open past ninety degrees, which means an open door occupies about twenty-one inches of the aisle in front of it. Set that against the aisle you actually have: at 36 inches of walkway you are left with roughly fifteen inches to stand in, which is not enough; at 42 inches you have about twenty-one, which works provided nothing opens opposite.
Two wide boxes facing each other across a galley is the case that bites — both doors into the same aisle, at the same moment, usually while somebody is carrying something. Against a wall, or under a window with nothing behind you, a wide pair of doors is exactly right and gives you one uninterrupted cavity with no centre stile to work around. That matters more than it sounds if anything long lives in the kitchen: a table leaf, trays, an ironing board, a folding step.
The alternative is splitting the run — an 18 plus a 24 comes to $880.75, $123.50 more than the single box, with two shorter doors and a stile down the middle. We split it by default and keep it single where something long has to go in, because a stile cannot be removed afterwards.
The widest sink base made
GN SB42 at $572.00 is also the cheapest thing at this width, which is not a mistake: a sink base has no shelf and no drawer, so you are buying a box and two doors. It earns the width in three situations — a large double bowl with a disposal and a filtered tap all wanting room below; a bowl that has to sit visibly off-centre to line up with a window; and a sink cabinet flanked by tall units, where it needs the visual weight to hold its own between them. Above 42 inches there is no sink base at all, so a plan needing more than this needs a different plan.
Common questions
- How much is a blind corner pull-out?
- GNK BPO-BLB42/45-L and GNK BPO-BLB42/45-R are $1,277.25 each, against $767.00 for the GN BLB42/45 cabinet they fit. The wider 48/51 version is $1,394.25.
- How do I know whether I need the left or right blind pull-out?
- It follows the side the blind end of the cabinet faces, which is set by which wall the corner turns into. Settle the corner before laying out either run, and confirm the hand on the order — it is not something to correct later.
- Is a 42-inch cabinet too wide?
- It depends on the aisle. Each of its two doors is about 21 inches, and an open door takes that much walkway. At a 36-inch aisle it is too much; at 42 inches it works if nothing opens opposite; against a wall it is ideal.
- What is the widest sink base cabinet?
- GN SB42 at $572.00. Nothing wider is made, so a run needing more than 42 inches under a sink has to be planned differently.
- Is there a 42-inch drawer base or full-height door base?
- Neither. Drawer banks end at 36 inches and the full-height door family ends at 39. At 42 the board is a sink base, a standard base and a blind corner.
