The Dust Proof Rail is a specialized component designed for use in sliding tracks and refrigerated cases to maintain environmental control. Constructed from aluminum with a satin anodized finish, this rail provides a protective seal between sliding tracks, which helps maintain low temperatures in refrigerated units. It functions to keep dust particles, smog, carbon, and other environmental debris out of showcases, contributing to the cleanliness and visibility of the display area. The rail features a height of 1/2", a base width of 7/16", an inner opening height of 5/16", and an inner width of 3/8". It comes in a total length of 144". This rail is suitable for various showcase and refrigeration applications where environmental control and cleanliness are required. The aluminum construction provides a stable frame for sliding glass panels, ensuring that the tracks remain clear of obstructions that could impede smooth operation. By sealing the gaps between tracks, it prevents the loss of cooled air, supporting the efficiency of refrigerated display systems.
