Floor guides keep the bottom of a sliding barn door from swinging away from the wall as it moves. Most hardware kits include a floor-mounted T guide — but if you have finished hardwood, tile, LVP, or any flooring you don't want to drill into, a wall-mounted guide does the same job without touching the floor. Both options are available here in multiple finishes — and if you're not sure which one you need, the answer is almost always determined by your flooring type. See our pre-order checklist for the full list of accessories to confirm before your kit ships.
The floor guide is the most commonly forgotten accessory after a hardware kit ships — and it's the one that stops an install cold when it's missing. Every barn door needs a floor guide to keep the bottom of the door from swinging away from the wall. Most hardware kits include one, but the guide that comes in the box is almost always a floor-mounted type — which requires screwing directly into the floor.
If that's not an option for your flooring, you need a different guide before you can finish the install. That's what this page is for. We carry floor-mounted guides, wall-mounted guides, and continuous guides — each suited to a different floor situation. If you're not sure which type came with your kit or which one you need, the guide below covers it.
Which floor guide do you need?
Three types, each solving a different problem. The right one depends on your flooring, how far the door travels, and how much modification you're willing to make.
| Type | How it mounts | Best for | Key requirement |
|---|---|---|---|
| Floor-mounted guide | Screws directly into the floor below the door | Concrete, subfloor, unfinished floors, or wood floors where the customer is comfortable screwing into the surface | Must be willing to put screws in the floor — not removable without leaving holes |
| Wall-mounted guide | Mounts to the baseboard, wall, or any vertical surface beside the door | Finished hardwood, tile, LVP, or any flooring you don't want to drill into | Needs a baseboard or wall surface within reach of the door's bottom edge |
| Continuous floor guide | Aluminum channel embedded into a routed slot in the floor | Doors that travel long distances where a static floor guide would disengage — the channel keeps the door controlled across the full length of travel | Requires routing a channel into the floor — significant floor modification. Note: the channel remains visible at floor level after installation |
Use case quick guide
The decision comes down to two things: your flooring and how far your door travels.
If your floor is concrete, subfloor, unfinished, or wood you're comfortable drilling into
The floor-mounted guide that came with your kit is almost certainly fine. This type works on concrete, subfloor, and wood floors — as long as you're comfortable with screws going into the surface. If you need a replacement or an additional one, the standard floor-mounted guide is the right call.
If your floor is finished hardwood, tile, LVP, or any surface you don't want to drill into
You need a wall-mounted guide. It mounts to the baseboard, wall, or any vertical surface next to the door opening — no floor penetration required. Note: a wall-mounted floor guide is not a practical option for double bypass installations, where the guide is typically positioned in the center of the opening away from any wall. For double bypass, a floor-mounted guide at the center of the opening is the standard approach. It does exactly the same job as a floor-mounted guide and leaves your flooring untouched. This is the most common reason customers come to this page after their kit arrives.
If your door travels a long distance and disengages from the guide
The continuous floor guide solves a specific problem: doors that travel long distances — longer bypasses or wide openings — where a standard static guide can disengage as the door slides past it. The channel runs the length of travel and keeps the door controlled throughout. It does require routing a permanent channel into the floor, and that channel will remain visible after installation. If floor modification isn't an option, multiple standard floor guides positioned along the travel path is an alternative — though the transition from the open floor onto the guide can be tricky to get right. Email us if you're working with a long-travel door and aren't sure which approach fits your situation.
