This floor guide for a sliding barn door is designed to guide door movement along either a floor or wall path. the guide weighs about 0.25 lbs. and measures roughly 4.5 in. long, 1.57 in. wide, and 1.97 in. high, providing a compact footprint for a range of installations. the roller assembly features a 1.49 in. Dia wheel with a thickness near 0.83 in., and the thicker profile is intended to promote smoother, more stable sliding. made from aluminum alloy, the guide resists rust and offers solid rigidity without adding excessive weight, making installation more predictable and the unit durable over time. a rubber roller with bearings helps dampen noise and supports smooth operation while helping protect door surfaces from scratches. the design uses a 90° integrated construction that can sit flush against walls and floors, and the guide rail edge is curved to reduce the chance of accidental contact during use. installation is supported by included tools and detailed instructions, with the option to mount on either the floor or the wall depending on the desired configuration. four adjustment settings on the track allow precise roller positioning. compatible with doors about 1 in. to 2.5 in. thick, this guide suits barn doors as well as bathrooms, kitchens, and closets.
