Thirty-nine inches: the box is made, the fittings are not
Reviewed September 2026 · Captivating Cabinets
Every article about this width tells you which cabinets stop being made above 36 inches. Fewer mention the more awkward half of it, which is that the accessory board stops too. Four base part numbers are stocked at 39 inches. Roll-out drawers are not made this wide. Drawer inserts are not made this wide. The blind-corner pull-outs skip it. If the plan involves anything sliding out of a cabinet, 39 is the width to think twice about.
The four boxes
That is the entire width, and two of the four are the same price.
| Part number | Displayed price | What it is |
|---|---|---|
| GN B39FD | $526.50 | Full-height double door — the widest FD box made |
| GN SB39 | $526.50 | Sink base |
| GN BLB39/42 | $685.75 | Blind corner, reaching 39 or 42 inches |
| GN B39 | $718.25 | Standard base, drawers over doors |
No drawer bank, no apron sink, no easy-reach or rotating corner, no 12-inch-deep version, no diagonal sink, no bench seat. Those families all end at 36. Three quarters of the base board simply skips this number.
Nothing on the accessory board fits
This is the part that catches people out, because the cabinet page and the accessory page are read at different times.
- Roll-out drawers run GNK ROD-B15 through GNK ROD-B36. The widest is $240.50 and fits a 36-inch box. There is no 39.
- Drawer inserts stop at GN CD-33/36 ($526.50) and GNK DCD-36 BLUM ($676.00). Nothing is cut for a 39-inch drawer, which is academic anyway since no 39-inch drawer bank exists.
- Waste pull-outs are made at 15, 18 and 21 inches only — they belong to the narrow widths and were never going to reach here.
- The blind base pull-outs are listed for the 42/45 and 48/51 corner boxes. Nothing is listed for GN BLB39/42.
So a 39-inch cabinet is a cupboard with a shelf in it, and it will stay one. That is a perfectly good thing to be — the ¾-inch adjustable shelf inside is 18 inches deep and takes a great deal — but it should be a decision rather than a discovery.
Where the width still earns its place
Two situations, and both are good ones. GN SB39 at $526.50 buys a bowl permission to sit somewhere other than the middle of its own box. Cabinets are planned from a corner; windows are not, and the two centre lines agree only by accident. Three extra inches either side of the sink is the slack that lets the fabricator slide the bowl under the glass while the cabinet face still lines up with everything else on the wall.
And GN BLB39/42 at $685.75 is insurance against a room whose corner is not quite where the tape said it would be. The pair of numbers in the code is the reason: how far the box is set out from the corner on the day decides whether it closes thirty-nine or forty-two inches of leg, with the space it leaves behind hidden by filler. Order the filler with it — GN BF3 is $26.00 and GN BF6 is $43.55. Nobody notices those two lines on a quote; everybody notices them missing from a pallet.
If thirty-nine inches of drawers is what the plan wants, put GN DB18 next to GN DB21 — $646.75 and $672.75, $1,319.50 together. Nobody should feel short-changed by that. Splitting the span means lighter fronts, less weight riding on any one pair of runners, and the option of making the narrower half a four-drawer while the wider half stays at three.
Common questions
- Is there a 39-inch base cabinet?
- Four of them, and no more. GN B39FD and GN SB39 both display at $526.50; GN BLB39/42 is $685.75; GN B39 is $718.25. Everything else you might draw at this number — drawers, an apron bowl, a rotating corner, a shallow carcass — is simply not built.
- Can I put roll-out shelves in a 39-inch cabinet?
- Not from the listed range. Roll-out drawers are made from 15 to 36 inches; the widest, GNK ROD-B36 BLUM E, is $240.50 and fits a 36-inch box. Nothing is cut for a 39.
- What does the slash in GN BLB39/42 mean?
- Two reaches from one box. Set tight, it closes thirty-nine inches; set out from the corner with filler covering the space behind, it reaches forty-two. The leading number is what the cabinet is called on the invoice.
- Why do the drawer banks not reach this far?
- Because the bank family tops out one step lower down the grid. A door needs a hinge; a drawer needs a pair of load-rated runners and a box wide enough to stay square on them, and that is where the engineering runs out. Pair an 18 with a 21 instead, $1,319.50 together.
- How much is a 39-inch sink base?
- GN SB39 displays at $526.50. Only one sink box is wider, and this is the one most often specified when the bowl has to shift sideways to line up with the glass above it.
