Locking and privacy questions are among the most common he helps customers work through — the right solution depends entirely on what you're actually trying to achieve.

Yes, sliding barn doors can be locked. But a barn door is a privacy fixture, not a deadbolt — the right latch depends on where the door is, whether it's a single or biparting door, and whether you need it to hold open as well as closed. We sell and install these every day. Here's exactly what works.
The real question: what are you actually trying to achieve?
Most people searching this have one of three situations:
Bathroom privacy — you need the door held closed while someone's inside. It has to be operable from the inside, and it has to handle humidity over time.
Bedroom or office privacy — the same idea with a cleaner look, and sometimes you want the latch to hold the door fully open as well as closed so it doesn't drift on the track. Still deciding whether a slider belongs on a bedroom in the first place? See is a barn door right for your bedroom.
Double or biparting doors — two doors meeting in the center need a latch built for that configuration, not a single-door lock.
What none of these is, is security. Every barn door latch keeps the door from sliding open, but none is designed to resist forced entry. A barn door rides on a 3/8" gap that runs the full perimeter of the door face — that gap is what lets the door slide, and it also means any latch can be pushed from the gap side, lifted off the track, or reached around. So what most people search for as a barn door "lock" is really a latch: it holds the door closed for privacy, but a barn door can be latched, not deadbolted. If you need to secure a room when you're away, a swinging door with a keyed lock is the right tool. For bathroom, bedroom, and office privacy, the latches below are exactly right.
The five locks we carry — and which to pick
We carry five latch types across two brands. Each suits a different door configuration and installation situation. Browse them all in our barn door locks and latches collection.
90-degree flip latch — simplest, no door modification
The strike plate mounts to the door face and the latch body to the jamb. Flip the arm 90 degrees to catch when the door is closed; flip it back to release before sliding. It works at the closed position, which covers the vast majority of single-door applications, and it requires no cutting into the door. Quick Ship, available in matte black and stainless steel. Best for most single-door bathrooms and bedrooms.
Cabin hook — the most versatile
The hook mounts to the door face and the eye to any nearby wall surface. It works at any door position — open, closed, or anywhere in between — so it holds the door fully open so it won't drift, as well as holding it closed for privacy. No door modification. Quick Ship, available in matte black and stainless steel.
Goldberg Brothers privacy latch — premium single-door pick
A paddle mechanism that catches between the door stop and the door jamb — the easiest latch we carry to operate. It does require a mortise routed into the door face and a strike plate on the jamb. Goldberg Brothers, available in standard and stainless steel. Single doors only.
Goldberg Brothers biparting privacy latch — for doors meeting at center
Designed for biparting doors — two doors that meet in the middle. When both close, flip the latch to catch the mechanism on the other door, holding both panels together. No door modification. Goldberg Brothers, available in standard and stainless steel. Not for single doors.
Teardrop lock — low-profile, but plan for routing
The teardrop mounts to the door jamb and swivels into a slot cut into the door face, so it sits nearly flush when engaged. That slot has to be routed into the door before installation, which makes it the most involved of the five to fit. Quick Ship, available in black only — it isn't rated for sustained moisture, so skip it for showers and steamy baths.
Choosing the right lock: quick reference
| Situation | Best lock | Why |
|---|---|---|
| Bathroom or bedroom privacy, no cutting | 90-degree flip latch | Simple, surface-mount, stainless option |
| Want to hold the door open too | Cabin hook | Works at any door position |
| Easiest to operate (single door) | GB privacy latch | Paddle action; needs a mortise |
| Two doors meeting at center | GB biparting latch | Built for biparting; no door mod |
| Lowest-profile look | Teardrop lock | Flush when engaged; needs a routed slot |
| Humid or high-moisture room | Any stainless option | Flip, cabin hook, GB privacy, GB biparting |
Two of the five need the door cut before installation — the teardrop (a slot in the door face) and the Goldberg Brothers privacy latch (a mortise). The Goldberg Brothers privacy latch has a router template available separately; the teardrop does not, so its slot has to be cut without one. If you're not sure what your latch requires, contact us before ordering and we'll confirm.
Can you lock a barn door from both sides, or with a key?
Not with these — they're one-sided privacy latches, operated from the room side only, and none are keyed. That's the right fit for a bathroom, bedroom, or office where you only need to keep the door closed from inside. If you genuinely need a barn door that locks from both sides or with a key, that's a specialty lock we don't currently carry — contact us and we'll point you in the right direction.
Matching the finish
Match the lock to your hardware finish — it's especially noticeable on a barn door because the latch mounts on the door face rather than recessed into the edge.
- Matte black hardware → matte black flip latch or cabin hook
- Stainless steel hardware, or any humid room → stainless flip latch, cabin hook, or Goldberg Brothers latch
- Goldberg Brothers kits → Goldberg Brothers privacy or biparting latch, in standard or stainless
The teardrop lock is available in black only. All our locks and latches are offered in finishes that sit cleanly alongside our hardware kits.
What about the privacy gap?
A latch keeps the door closed, but it doesn't address the small gap between a barn door and the wall that lets light and sound pass through. For bathrooms and bedrooms especially, that matters. Three things help, alongside any latch:
- Size the door with more overlap. Standard sizing adds 2" per side; for privacy, go to 3" per side to cut the light bleed at each edge.
- Add pile or brush weatherstrip to the door edges to close the gap. Use pile or brush specifically — not foam or rubber compression seals, which drag on a sliding door and keep it from closing fully over time.
- Add a flush pull on the wall-facing side so you can pull the door closed from inside the room without reaching around the edge. Browse our flush pulls collection.
