For installations where there isn't enough clearance on either side of your doorway for a bi-part barn door configuration, the bypassing barn door hardware kit is an excellent alternative. By cantilevering one door in front of the other with the bypass barn door track, you can gain greater access to your entryway by stacking barn doors on top of each other. Double track bypassing sliding door hardware kits offer greater flexibility than single track bypass barn door hardware, but require more clearance above the doorway. Many people prefer the look of the single track bypass barn doors, but they aren’t quite as dynamic as the double bypass barn door hardware. The bypassing doors are overlapped on the track and cannot be separated. So whether you need bypass barn doors for closet, pantry or any other room in your house, a sliding bypass barn door hardware kit is perfect for your installation!
Bypass Barn Door Hardware Kits: Space-Saving Sliding Solutions
When you want the aesthetic appeal of a sliding door but lack the adjacent wall space for it to slide open, a standard single track won't work. This is where bypass hardware comes in. Bypass systems allow multiple doors to overlap each other, making them the ultimate space-saving solution for wide closets, master bathrooms, and tight hallways.
At Dusty’s Rustic Rolling Doors, we specialize in heavy-duty bypass barn door hardware kits engineered to handle the complexity and weight of overlapping doors without compromising on style or smooth functionality.
What is a Bypass Barn Door System?
A bypass barn door system is a sliding hardware setup designed for two or more doors. Instead of sliding out over an empty wall, the doors slide on parallel tracks (or use specialized hangers) to overlap one another. This means the doors are contained entirely within or just slightly outside the door frame opening, similar to traditional sliding closet doors but with the exposed, stylish hardware of a barn door.
Single Track vs. Double Track Bypass Hardware
Understanding the mechanics of how the doors overlap is critical to selecting the right hardware for your space.
Double Track Systems
This is the standard and most robust bypass setup. It utilizes two parallel tracks mounted to the wall via specialized bypass extension brackets. The inner door glides on the track closest to the wall, while the outer door glides on the track positioned further out.. This configuration spreads out the weight of the doors over two tracks. One advantage of the double track system is that each door moves independently from each other and floor guides can be foregone if they pose a tripping hazard. They also require less overlap between the doors when compared to the Single Track Bypass configuration.
Single Track Bypass Systems
If you have limited space above your door frame, a single-track bypass system is a brilliant alternative. This setup uses a single track mounted to the wall, but utilizes specialized Z shape roller brackets for the outer door. The outer door hangs over the inner door, allowing both to slide on the same track. This significantly reduces the required ceiling clearance and creates a sleeker profile. It also has a built-in “come-along system” which will pull one door when the other is moved. Some disadvantages of this system are that the doors are always overlapping each other and can never be pulled apart. This built-in overlap requires wider doors than are required for the Double Track system. It also requires that the bottom of the doors be routered for the use of mandatory floor guides.
Double Bypass (2 Doors)
The most common setup. Two doors cover a single wide opening. You can slide either door to the left or right, allowing access to half of the opening at any given time. Both doors can be pushed to one side of the doorway to fully clear the opening if there is limited space on the other side of the doorway.
Triple Bypass
This configuration mounts three doors on three separate tracks. This allows all three doors to stack flush on top of each other when in the open position. This allows for the maximum amount of doorway coverage with the minimum door width. It also allows for the weight of the doors to be spread over three tracks. Floor guides can be foregone if they pose a tripping hazard.
3 or 4-Door Bypass Systems
For massive openings like room dividers or sprawling wardrobes, three or four doors can be configured to overlap. These complex systems require precise track alignment and often utilize a combination of double tracks and extended brackets to allow multiple doors to be mounted on two tracks.

Style & Finish Options
Overlapping doors are a visual centerpiece, meaning the finish of your track and rollers will anchor the room's design.
Matte Black & Rustic Industrial
A matte black double bypass track immediately grounds a room, bringing an earthy, rustic industrial feel. The dark, powder-coated steel pairs exceptionally well with heavy wood grains, knotty alder, or reclaimed lumber doors, making it a favorite for modern farmhouse designs.
Modern Brushed Nickel
For a cleaner, more contemporary look, brushed nickel bypass hardware offers a minimalist touch. The silver hardware is highly durable, reflects light to brighten tight spaces, and is an excellent pairing for frosted glass doors or flat-panel designs.
Frequently Asked Questions (FAQ) & Installation Guide
Bypass setups carry double the weight and require precise alignment. Review these common technical questions to ensure your space is ready for a seamless build.
How to calculate door overlap for double track bypass barn doors?
To prevent an unwanted gap from showing between the overlapping doors when they are closed, you must account for overlap in your door sizing.. We recommend you take the width of your opening, divide that measurement by 2 and add 4”. For example, if your opening is 88” wide, two 48” doors would be recommended [(88” ÷ 2 = 44”) + 4” = 48”]
How to calculate door overlap for single track bypass barn doors?
Because of the design, the doors are always overlapping and cannot be pulled apart. This requires wider doors than what would be necessary for the double track bypass system. The amount of overlap between the doors is determined by where the hangers are placed relative to the side edge of the door, but the general recommendation is that the combined width of both doors be 12” - 18” wider than the doorway. Please consult the blog article below to see the formula for calculating recommended door width.

How do I choose low ceiling clearance bypass barn door kits?
If you have less than the standard 8 of headroom required for double-track extension brackets, look specifically for a "Single Track Bypass System." Because the single track bypass kits do not use bypass brackets that extend above the track, these kits can operate with as little as 6 inches of ceiling clearance above the door (which sits ½” off the ground).
What are the drywall blocking requirements for heavy double bypass tracks?
Bypass hardware carries the weight of two (or more) doors, which can easily exceed 200 pounds. You cannot mount bypass brackets solely into drywall. You must anchor the hardware directly into wall studs. We strongly recommend installing a structural header board ( 1x8 piece of solid wood secured to your wall studs) and mounting your bypass brackets directly to the header for maximum safety and stability.
How to install a double bypass floor guide?
Each bypass kit comes with with one dual clip floor guide per door. These guides can either be used as a “fin style” guide that fits into a groove cut into the bottom of the door, or as a “cradel style” where each side of the guide fits on the outside of the door. This configuration doesn’t require a groove to be cut in the door. For single track bypass kits, the fin style guide is mandatory as the weight of the outer door is pressing on the inner door. Since each door is on it’s own track for the double track bypass kit, the guides can be forgone to prevent a tripping hazard or avoid drilling into a floor surface. If floor guides are not used, excersise caution when opening and closing the door so that the doors do not bang into each other, although they are not at risk of coming off of the track.
Can soft close mechanisms be used on bypass barn door hardware?
Yes, barn door soft close mechanisms can be used for double track bypass kits with two doors. They can also be used while mounting multiple doors to the same track, but only if each doors has its own range if motion (e.g. 4 doors bi-parting). If two doors on the same roll over the same section of track the soft close will not work properly (e.g. pushing two doors on the same track to the same side of the doorway). For this reason it is not recommended for single track bypass kits nor for Spoke Wheel hanger kits.
