The drawer slides are very quiet. The soft close feature prevents drawers from slamming shut as well as not completely closing. The slides mount easily to the cabinet box and drawer box. They require a 1/2\" space on each side of the drawer box. Although the quality of the slides is high, the cost of the slides is not. These slides are the best deal I've seen on 22\" soft close slides for a pack of six, and they are a bit less if bought in a pack of ten. Really good slides for cabinets and furniture.
