ABSTRACT:
A greenhouse with two gable ends formed of a framework which extends between the ends and which includes a sloped roof or eave and also includes sloped gable end bars supported atop vertical bars included in the gable ends. Wedge shaped gable adaptors of reversible configuration are inserted between the tops of the vertical bars and the lower surfaces of the sloped bars to provide a firm support for the sloped bars and a connection between the vertical and sloped bars. The vertical bars are of like configuration in cross-section and are aluminum extrusions arranged in mirror image of each other. Use of the reversible adaptors enable the same extrusion design to be used on opposite ends of the greenhouse. The adaptor structure includes prongs which are inserted into the extrusions which are hollow. The prongs have relative lengths and widths which facilitate mounting of the adaptors in the partially erected greenhouse. The mounting method includes bolting the adaptors to the bars by the use of openings provided in the adaptors for this purpose. Shims are employed with a design to enable the insertion of the same after the adaptors have been connected to the bars.
