<p>An insulated door (1.0029 includes a door frame made of four side members (1.006, 1.008, 1.010, 1.012) connected by four corner connectors (1.014, 1.016, 1.018, 1.020). The frame members are profiled "L" shaped extrusions having outer panel locating ribs (6.035), and inner panel retaining slots (6.007). The corner connector has a base (4.044) with a projecting post (4.040). A first pair of connector tabs (4.022, 4.044) project from adjacent sides of the base to cooperate with first connection slots (6.028) of adjacent side members and a second pair of connector tabs (4.042, 4.043) project from the post to cooperate with connection slots (6.026) of the adjacent side members. The outer panel is located on the opposite side of the frame by location ribs (6.036). The legs (6.009, 6.011) of the extrusion define a space D between the inner and outer door panels, and this space is filled with foam insulation.</p> |
