Abstract
A transition sleeve for a double wall structure such as a refrigerator cabinet used to pass tubing or the like through juxtaposed apertures formed therein. The sleeve includes a unitary tubular body of relatively rigid material having a plurality of radially extending integral locking tabs at one end thereof for securing to one of the refrigerator walls through a complementary apertured opening. The tabs have camming faces formed thereon to facilitate rotation about the opening after being inserted therethrough. On a radially extending plane offset from the locking tabs are a plurality of equiangularly disposed stop pads which positively locate the rotational position of the sleeve on the wall. The longitudinal ends of the body include annular flanges which are flared outwardly to sealingly engage the walls perimetrically of the apertures on the cavity side thereof. The tubing is sealed to the core of the sleeve by the use of gum or the like.
