This product offers 6 pairs of 14-inch side-mounted steel ball bearing drawer slides, complete with mounting screws (extra screws provided for spare use). Please note that mounting brackets are not included and need to be purchased separately if required. The slides feature a side-mounted steel ball bearing design, ensuring silent operation. With dimensions of 14 inches in length, 1.77 inches in width, and 0.5 inches in thickness, they perfectly fit a variety of drawer needs. In terms of material, the product is made of high-quality cold-rolled steel with a zinc-plated surface, providing rust resistance and durability for long-term use without worry. The specially designed black buckle on the third channel facilitates easy installation and removal, greatly simplifying the installation process. Additionally, the slides are equipped with nylon rubber, which effectively reduces noise during opening and closing, creating a peaceful living environment for your family. When selecting the size of drawer slides, please make sure to measure the length of the drawer (excluding the frame board). If the length is not a whole number, it is recommended to choose a size 1 inch shorter. Furthermore, the length of the slides should not exceed the depth of the cabinet. For cabinets with a face frame, a rear mounting bracket is required, while for cabinets without a face frame, the slides can be mounted directly on the side of the cabinet.
