The Curtron SSW-D-CURTRON-15-GRAY 48 X 84 Opening Size 4"-10 Degree Freezer Door ETL Labeled is a meticulously engineered solution for cold storage environments that demand reliable insulation and durability. Specifically designed with a 48 x 84 opening size, this door is equipped with a 4-inch wall thickness, optimizing its thermal retention capabilities for environments as low as -10 degrees. The door features an embossed gray galvanized front and back, coupled with a diamond tread aluminum of 1/16" thickness, enhancing its structural integrity. It includes a 12" high front and back impact plate for increased protection against collisions. The construction incorporates through-wall bolts with zinc fasteners for secure installation. The fiberglass reinforced plastic frame, 1.5" thick, is complemented by both a 3-sided white front frame and a 3-sided white mirror frame, providing an aesthetically pleasing finish. Its 1" thick molded polymer plastic adds to its robust performance. The door's functionality is further enhanced by a cold storage chrome standard hinge, a chrome soft touch latch with padlocking, and an inside release push side latch, ensuring security and ease of access. A standard closer and spring hinge mechanism allow for smooth operation, while the absence of a window maintains its focus on thermal efficiency. This door is particularly well-suited for industries requiring stringent temperature control, including food service, pharmaceuticals, and cold storage logistics.
