Package contents 2 x Spring Buffer Dampers Overview A pair of adjustable spring buffer dampers designed for sliding barn doors. Mounted behind the rail on a flat track, these dampers slow doors as they reach the end of travel for a quiet, controlled close. Key features and benefits Gentle, quiet closing: Builtin absorption slows the door and reduces impact noise, preventing disturbances when doors are closed. Adjustable damping: Tightening can be adjusted to match door weight and closing speed, allowing fine tuning for different door sizes and materials. Easy retrofit: Installs on a flat barn door track behind the rail with no drilling required, so it upgrades existing hardware without modifying the door or track. Durable material: Made from POM polyoxymethylene for stable performance and long service life under repeated use. Universal appearance: Black color blends with most barn door hardware finishes. Compact size: Each damper measures 31.00 x 2.00 x 2.00 cm (12.18 x 0.79 x 0.79 inch), suitable for standard sliding door tracks. Performance and compatibility Designed to work with flat track sliding barn door systems where there is room behind the rail to attach a damper. Reduces impact forces at the end of travel, helping to protect rollers and other hardware components from sudden shocks. Adjustable mechanism lets you set the damping strength to suit lighter interior doors or heavier exterior style doors. Installation and use Mount behind the rail on the flat track; no holes need to be drilled into the track or door. Turn the adjustment to increase or decrease the tightening effect according to the weight and closing speed of the door. Regular visual checks are recommended to confirm proper positioning and adjustment over time. Typical use scenarios Interior sliding barn door for living rooms or bedrooms: Adds silent, controlled closing to prevent loud slams and reduce disturbance. Closet or pantry sliding doors: Improves daily convenience by softening the final movement and reducing wear on track hardware. Office partitions or room dividers: Provides a quieter workplace environment by damping the motion of frequently used sliding doors.
