Classic J-Strap Barn Door Hardware Kit — In Stock, Ships Next Business Day

Available configurations: 6 ft track (single door), 7 ft track (single door), 12 ft track (two-door biparting), 14 ft track (two-door biparting). Need a different length? See the made-to-order J-strap kit.

Available finishes: Matte Black Texture, Silver Metallic. Need a different finish? The made-to-order kit adds Black and Arch Bronze.

Door weight: Up to 200 lbs. Over 200 lbs? See heavy duty hardware.

Door thickness: 1-3/8 in to 1-3/4 in. Outside this range? See heavy duty hardware.

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: 4-1/2 in minimum above the top of the door — not above the rough opening. A taller door raises the track, so check this against your final door height, not the opening. Less than 4-1/2 in? Straight strap hardware needs only 4 in.

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.

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.

Weight capacity: 200 lbs per door

Door thickness: 1-3/8 in to 1-3/4 in

Track lengths: 6 ft, 7 ft (single door) · 12 ft, 14 ft (two-door biparting)

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

Ceiling clearance required: 4-1/2 in above the top of the door

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: Stock sizes, so the standard window applies — 25 days from delivery with pre-approval and a 25% restocking fee. 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
• J-strap roller sets with Delrin wheels
• Wall mounting hardware — lag bolts, carriage bolts, washers, lock washers, hex nuts, and spacers
• 1/2 in and 1 in extension spacers — included, to stand the track off the wall when casing or baseboard projects 1/2 in or more
• 2 track stops and 2 anti-jump blocks per door
• Felt pads and rubber bumper bands — finish the track ends as a quiet "stay" or as a "bumper"
• 1 floor-mounted T-guide per door, with screws
• Installation instructions

Fastener finish: black oxide with Matte Black Texture; clear zinc with Silver Metallic. The J-strap is a face-mounted hanger, so the bolt heads sit on the door face and are visible once installed — they are not powder coated to match at this tier.

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.

The 12 ft and 14 ft tracks ship in two sections joined with a connection plate, which is included. Your header board needs to span continuously across the joint, and the connection isn't visible once installed.

The included floor guide is floor-mounted and screws into the floor. If you have finished hardwood, tile, or LVP, use a wall-mounted floor guide instead — it does the same job without drilling.

Handles and soft close are not included — add them before checkout if needed.

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 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 — browse our floor guides collection
• Soft close: Adds a controlled stop at the end of travel — see the soft close mechanism kit

The track must be at least 2× the door width for the door to fully clear the opening. Here's how the four available lengths map to door widths:

• 6 ft track (72 in): Single door up to 36 in wide
• 7 ft track (84 in): Single door up to 42 in wide
• 12 ft track (144 in): Two-door biparting — doors up to 36 in each
• 14 ft track (168 in): Two-door biparting — doors up to 42 in each

Measure the door panel, not the rough opening. If your door width falls between sizes, order the longer track.

All four are stock lengths and return normally. If you need a length that isn't listed, the made-to-order J-strap kit can be cut to any length at the Goldberg Brothers factory, with the powder coat applied after cutting, at no additional cost — and full warranty coverage intact. The trade-off: a length cut to order is a custom order and can't be returned, so confirm your measurements first.
