Sealing arrangement for an enclosure

An enclosure comprising:

• a door;
• and
• an enclosure body including:
• a back wall and side walls that define an interior compartment of the enclosure body;
• and
• a sealing arrangement including:
• a first wall portion that extends from the side walls, opposite the back wall, in a first direction toward a front opening of the enclosure, the first direction being parallel to the back wall;
• a second wall portion that extends from the first wall portion, opposite the side walls, in a second direction that is perpendicular to the first direction;
• a third wall portion that extends from the second wall portion, opposite the first wall portion, in a third direction that is parallel to the first direction, the third wall portion defining an open hem that includes:
• an inner perimeter that defines a door opening for the enclosure, and a rectangular outer perimeter with a plurality of radiused corners;
• and
• a gasket that receives the rectangular outer perimeter of the open hem, including the plurality of radiused corners, to extend continuously around the outer perimeter of the open hem and provide a seal at the door;
• wherein, for each radiused corner of the plurality of radiused corners, a ratio of (i) a radius of the radiused corner to (ii) a width between the inner and outer perimeters along an adjacent side section of the open hem is in a range from 11:6 to 12:7.

A method of manufacturing a sealing arrangement of an enclosure, the method comprising:

• forming an enclosure body with a front wall that defines a front opening, wherein the front wall includes an offset extending from side walls of the enclosure body toward the front opening in a first direction;
• forming a flange that extends from the offset in a second direction away from a back wall of the enclosure body;
• forming an open hem that extends from the flange, opposite the offset, in a third direction that is opposite the first direction, wherein the open hem has an inner perimeter that defines a door opening aligned with the front opening, and an outer perimeter that includes side sections and radiused corners adapted to secure a continuous gasket to the open hem along the outer perimeter, and wherein a first ratio of (i) a first radius of a first of the radiused corners to (ii) a width between the inner and outer perimeters along a first side section adjacent to the first radiused corner is in a range from 11:6 to 12:7;
• and
• mounting a continuous gasket around the outer perimeter of the open hem, including the radiused corners.
