A refrigerated display cabinet IG door includes inner and outer polygonal annular frames each formed as a single substantially homogenous polymeric/copolymeric injection molded member. An insulated glass unit is bonded to the inner and outer frame members which are forcefully held together by a periphery snap fastening mechanism which avoids conventional use of clamps, vises or the like during adhesive cure/set-up. Conventional pivot pins carried by the display doors are uniquely guided into pivot pin openings through guiding and locating members which can be snap-secured in openings of a frame in a display case in but a single position.
