Hidden Roller Barn Door Hardware Kit

Door weight: Up to 125 lbs with the Standard Roller; up to 250 lbs with the Heavy Duty Roller. Not sure which to choose? If your door is solid hardwood or a heavy panel, go Heavy Duty — there's no downside to choosing the higher-capacity roller.

Door width: Your door must be wider than the rough opening. For standard rooms plan for 2 in of wall overlap on each side — opening + 4 in. For bedrooms and bathrooms, 3 in per side gives better privacy — opening + 6 in. If wall space is tight, 1/2 in per side is the minimum functional overlap, but it is a floor rather than a target. For a biparting pair, size each door to (opening + 4 in) ÷ 2. See our measuring guide for full sizing formulas.

Door height: Hidden roller door height is calculated differently from standard sliding hardware, and it is measured from the rough opening — not from the door. The roller assembly mounts to the back of the door and sits in the space above the rough opening, so the door must be significantly taller than the opening. Door height = rough opening height + 4-3/8 in minimum; opening + 5 in is recommended for comfortable installation clearance. All of that extra height goes above the opening — do not add the floor gap on top of it. This is the most common measurement mistake on hidden roller installations; if the door isn't tall enough, the assembly won't fit.

Door thickness: 1 in or thicker.

Ceiling clearance above rough opening: Unlike standard sliding hardware — where clearance is measured from the top of the door — hidden roller clearance is measured from the top of the rough opening. The ceiling must be at least 4-3/8 in above the top of the rough opening; 5 in is recommended. Measure this before ordering. If your ceiling runs close to the top of the opening, confirm this clearance first.

Door-to-wall clearance: Hidden roller holds the door 1 in off the wall — more than any other hanger style, because the roller assembly sits behind the door. Standard sliding hardware holds the door 3/8 in off the wall. Account for the extra inch when you plan handle and pull placement.

Trim clearance: Hidden roller holds the door 1 in off the wall, and about 1/8 in of that is gap between the door and any trim — so casing, baseboard, or trim projecting 7/8 in or less needs nothing added. That's more tolerance than standard duty sliding gives at a 1-3/4 in door thickness, where a 1/2 in projection already calls for extra spacers. If your trim projects more than 7/8 in, add the 1/2 in spacers from the product options above before checking out — they're extra spacers on top of the ones already in the kit. Trim that sits above the opening is a different problem — that one is solved by sizing the door taller, never by spacers.

Wall clearance beside opening: Must equal full door width on the slide side. Limited clearance? See bypass hardware or bifold hardware.

Wall header: A 1×6 hardwood header board is the minimum for every installation — oak, maple, or poplar, not pine. It does two jobs: it spreads the load, and it decouples the track's bolt spacing from your stud spacing. The track's mounting holes rarely line up with studs, so a continuous board lag-bolted into the studs (3/8 in × 3 in lag bolts) gives the track solid backing anywhere along its length. Never mount to drywall alone. If your wall has no usable studs at all — glass, steel framing — ceiling mount hardware is the fallback, but note that it is different hardware entirely: there is no hidden roller ceiling mount option.

Track length: At least 2× the door width for a full unobstructed opening. See the track length section below.

For the full pre-order checklist see our measuring guide.

Hardware for 1 Door:

• 2 hidden hangers with 8 hidden hanger screws
• 6 washers
• 6 3/8 in spacers
• 2 track stops
• 1 felt pad
• 1 T-guide (floor-mounted) with 2 T-guide screws
• 6 hex lag bolts
• Track — in the length you select

Hardware for 2 Doors (biparting): All component quantities doubled except the track.

Fastener finish: black oxide with Matte Black Texture, Black, and Arch Bronze; clear zinc with Silver Metallic. Fasteners are not powder coated to match at this tier. Nothing shows on the door face — the rollers mount behind the panel — but the lag bolts securing the track to the wall sit on the track face and are visible after install. The touch-up paint option above lets you paint those to match your finish.

Lag bolt length varies by kit and by your mounting setup — confirm the exact length in your kit's instruction manual rather than buying substitutes ahead of time.

Doors wider than 60 in need a third hanger. Email us at info@thebarndoorhardwarestore.com before ordering so we can confirm the right configuration for your door.

Tracks over 7 ft 6 in ship in multiple sections with connecting hardware. Your header board needs to span continuously across the joint.

The included T-guide is floor-mounted and requires screws into the floor. If you have finished hardwood, tile, or LVP you can't drill into, you'll need a wall-mounted floor guide instead — browse our floor guides collection.

Handles and a latch are not included — add them before ordering to avoid a second shipment. Soft close is not compatible with hidden roller hardware.

Hardware kits don't include handles or a latch — plan for these before ordering to avoid a second shipment:

• Handle: For the room-facing side of the door — browse our handles collection
• Flush pull: For the wall-facing side if the door is operated from both sides — browse our flush pulls collection
• Latch: Keeps the door closed deliberately — browse our latches collection
• Wall-mounted floor guide: If you have finished hardwood, tile, or LVP you can't drill into, a wall-mounted floor guide replaces the included floor-mounted T-guide — browse our floor guides collection
• Trim clearance spacers: Only if your casing or baseboard projects more than 7/8 in — your kit already covers anything up to that. Select it in the options above
• Touch-up paint: For painting the visible track bolt heads to match your finish — select it in the options above

The track must be at least 2× the door width for the door to fully clear the opening. Measure the door panel — not the rough opening.

• Single door: 2× door width — e.g. 40 in door → 80 in track minimum
• Biparting (2 doors): 4× each door's width, which is the same as 2× the combined width — e.g. two 32 in doors → 128 in track minimum

For biparting: add both door widths together first, then double the combined total. Worth knowing if you're weighing one door against two — a biparting pair needs the same total track length a single door would need over the same opening.

Ordering a track that's too short is the most common mistake — the door won't fully clear the opening. When in doubt, order the next size up.

The track lengths in the product options above are stock sizes and ship as ordered. If you need a length that isn't listed, Goldberg Brothers will cut track to your exact length at the factory and apply the powder coat after cutting, at no additional cost — so there's no exposed steel, no field cutting, and the limited lifetime warranty stays intact. The one trade-off: a length cut to order is a custom order and can't be returned, so confirm your measurements before you request one. Start on our custom quote page or email info@thebarndoorhardwarestore.com.

Goldberg Brothers rollers use sealed bearings that run dry. Do not lubricate the track or rollers. Silicone spray, WD-40, and white lithium grease all attract dust, build up in the channel, and make the door harder to roll, not easier. If a door starts to drag or squeak, the cause is almost always debris in the track or a level issue — wipe the track channel with a dry cloth (damp first, then dry, for stubborn grime) and check that the hardware is still tight. A genuinely worn roller gets replaced, not lubricated.
