This face frame installation kit is made of cold-hardened cold-rolled steel with a galvanized surface, specially designed for cabinet face frame structures to provide stable support for drawer slides. If the cabinet has a face frame, this kit can effectively assist in installing the rails to ensure smooth drawer operation. The kit includes 10 pairs of rear/side mounting brackets and installation screws, suitable for drawer slides with a width of 45 mm (1.77 in.), and can extend the original length of the slide by 2.75 in. (70 mm) to meet the installation needs of deeper cabinets. The high-strength characteristics of cold-hardened cold-rolled steel combined with galvanized anti-rust technology make it both durable and corrosion-resistant, suitable for long-term use in cabinet renovations in humid environments such as kitchens and bathrooms, providing reliable extended support for the drawer system.
