Abstract
A door includes a U-shaped frame having opposing side channels. The channels include peripheral, inner and outer walls with the inner wall being of a larger size and configuration than the outer wall. A glass insert slightly smaller than the size of the inner wall is inserted therethrough and is guided to a centered position seated upon the outer wall. An open frame insert is slid into the two side channels, and a plurality of opposing pairs of walls deflect the open frame insert into bearing engagement with the glass insert. A peripheral edge of the open frame insert defines a peripheral channel with a terminal edge of the door frame inner wall for receipt therein of a peripheral securing boss of an elastomeric peripheral seal.
