Joint members for refrigerator appliance casings

A refrigerator casing, comprising:

• a main casing body, the main casing body comprising a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a top wall extending between the first sidewall and the second sidewall;
• a casing bottom connected to the main casing body, the casing bottom comprising an upper flange extending generally along the lateral direction between the first sidewall and the second sidewall;
• a back wall connected to the main casing body, the back wall comprising a lower flange extending generally along the lateral direction between the first sidewall and the second sidewall;
• and
• a joint member comprising a body extending between a first end and a second end generally along the lateral direction, the joint member connected to the upper flange and the lower flange, the joint member comprising a first protrusion extending from the body at the first end and a second protrusion extending from the body at the second end, the first protrusion disposed within a first pocket defined in the casing bottom, the second protrusion disposed within a second pocket defined in the casing bottom.
