Minimalist Straight Top Mount Barn Door Hardware Kit

Door weight: Up to 75 lbs with the standard two-roller setup, or 112.5 lbs with a third roller added. Between 75 and 100 lbs, the J top mount kit covers that range on two rollers — same top-edge mounting, slightly curved profile rather than flat. Between 100 and 200 lbs? See the J-strap kit if visible straps are acceptable, or hidden roller hardware if keeping the door face clean is the priority. Over 200 lbs? See heavy duty hardware.

Door thickness: 1-3/8 in to 1-3/4 in. Doors up to 2-1/4 in? See heavy duty hardware — note that heavy duty offers the J top mount and flat top mount, not the straight top mount.

Door width and hanger count: Two hangers handle doors up to 48 in wide. Between 48 and 60 in, a third hanger is optional. Above 60 in it's required. A third hanger isn't a checkout option — request one on our custom quote page with your door width and we'll spec it.

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

Ceiling clearance above the door: 4 in minimum, measured above the top of the door — not above the rough opening. That's the tightest requirement in the standard duty lineup, matched only by the straight strap and horseshoe. A taller door raises the track, so measure against your final door height.

Wall header: A 1×6 hardwood header board is the minimum for every installation — oak, maple, or poplar, not pine. It spreads the load, and it decouples the track's bolt spacing from your stud spacing, since the track's mounting holes rarely line up with studs. Run it past the length of the track to the next stud on each side and lag-bolt it into the framing with 3/8 in × 3 in lag bolts. Never mount to drywall alone. If your wall has no usable studs at all — glass, steel framing — ceiling mount hardware is the fallback, but it's a different product line and needs exactly 6 in between the top of the door and the ceiling.

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 treat that as a floor rather than a target. See our measuring guide for full sizing formulas.

Door height: Measure the rough opening height and add 1 in minimum — the extra inch covers the top of the opening, and the hardware sets a 3/8 in gap at the floor. If there is casing or trim above the opening, the door needs to be at least as tall as the top of that casing so the track clears it entirely. Never mount the track to trim. Going taller raises the track, so recheck your ceiling clearance before ordering — and on this kit you only have 4 in to work with. With thick carpet, confirm the floor clearance holds along the full travel path.

Trim beside the opening: If casing or baseboard projects 1/2 in or more from the wall, use the included extension spacers to stand the track off. A 1-3/8 in door clears up to 1 in of projection; a 1-3/4 in door clears up to 1/2 in. Deeper than that, heavy duty hardware with its add-on spacer kit reaches 1-1/4 in.

Track lengths: 4 ft, 4 ft 8 in, 5 ft, 5 ft 4 in, 6 ft, 7 ft, 8 ft, 9 ft 4 in, 10 ft, 10 ft 8 in, 12 ft, 14 ft, 16 ft

Finishes: Matte Black Texture, Black, Arch Bronze, Silver Metallic

Configurations: Single door or biparting (two doors on one track)

Track centerline height: Door height + 1-1/2 in — confirm against your kit's instruction manual before drilling

Ceiling clearance required: 4 in above the top of the door

Door-to-wall clearance: 3/8 in

Trim clearance: 1/2 in and 1 in extension spacers included

Soft close: Available as an add-on, and can be retrofitted after install

Handles: Not included — order separately from our handles collection

Returns: The listed track lengths are stock sizes and return under the standard window — 25 days from delivery with pre-approval and a 25% restocking fee. A length outside the listed options is a custom order and can't be returned. See our return policy

Warranty: Limited lifetime warranty against manufacturing defects. Hardware is sold as rustic-finished, so minor marks and patina are characteristic rather than defects. Wear items — felt pads, rubber bumpers, and the soft close mechanism — carry a one-year window.

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

• Steel track, 1-1/2 in × 3/16 in, in your selected length
• Straight top mount hanger sets with Delrin wheels
• Wall mounting brackets, bolts, and spacers
• 1/2 in and 1 in extension spacers for trim clearance — included, no additional purchase needed
• 2 track stops per hanger set
• 1 floor-mounted T-guide per door
• 2 anti-jump blocks per door
• Felt pads and rubber bumper bands — finish each track end as a quiet "stay" or a "bumper"
• Installation instructions

Fastener finish: clear zinc with Silver Metallic; black oxide with Matte Black Texture, Black, and Arch Bronze. Because this is a top mount, none of it lands on the door face — the hangers attach to the top edge. The lag bolts securing the track to the wall do sit on the track face and are visible after install, and since nothing at this tier ships powder coated to match, the touch-up paint option lets you paint them to your finish.

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

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

If you have finished hardwood, tile, or LVP, you'll need a wall-mounted floor guide instead of the included floor-mounted guide.

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

• Handles: Bar pull or D-pull for the room-facing side — browse our handles collection
• Flush pull: For the wall-facing side if the door needs to be 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 — browse our floor guides collection
• Soft close: Select it in the options above, or retrofit it later — see the soft close mechanism kit
• 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. 36 in door → 72 in track
• Biparting (2 doors): 4× each door's width, which is the same as 2× the combined width — e.g. two 36 in doors → 144 in track

For biparting, size each door to (opening + 4 in) ÷ 2, then add both widths together and double the total. Worth knowing if you're deciding between one door and two: a biparting pair needs the same total track length a single door would need over the same opening.

The lengths listed in the options above are stock sizes. They ship as ordered and return under the standard 25-day window.

If the length you need isn't listed, request a custom quote. Goldberg Brothers cuts the track to your exact length at the factory and applies the powder coat after cutting, so there's no exposed steel, no field work, and the limited lifetime warranty stays intact — priced the same as the next standard size up. The one trade-off: a length cut to order is a custom order and can't be returned, so confirm your measurement before you submit it.

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 and check that the hardware is still tight. A genuinely worn roller gets replaced, not lubricated.
