Concealed Sliding Barn Door Hardware with Soft Close. Unfortunately, I have not been able to install this due to some chronic pain issues, but I can attest to the functionality and build quality. This is a heavy-duty kit. The kit is very heavy, a reflection of the quality of materials used. I have tested the functionality, and it slides very smoothly. The soft close function works well. I have also watched a video of the same or similar kit, and the function and look were great.
