Technical Innovations Rectangular Skirt - HD10
The Technical Innovations Rectangular Skirt - HD10 is an eight piece fiberglass skirt to make transition between the circular observatory base ring and a flat or sloping roof or building edge. The horizontal flange of the RS10 fastens under a base ring (or wall ring) flange, while a vertical flange ("drip flange") attaches to your square structure. The skirt slopes downward 4 inches to the 10'7" square.
In a typical installation, the dome base ring will sit on the 3 in. horizontal flange of the skirt. You will need framing below this flange to support the dome weight. This framing must be 4 in. higher than the top of your building, because the skirt has a downward slope. Also typical, the drip flange of the skirt will fit over the upper edge of your structure. To make the skirt fit well, the outside dimension of your structure should be 10 ft. 7% in. to allow for the thickness of the fiberglass material. You can get a better fit if you bevel the corners of your framing. This is because the underside of the fiberglass has a slightly curved surface in the corners.
To assure that the skirt fits to the wall/base ring as well as possible, you need to measure and cut your support structure with care. It is best to use a section of base ring as a guide for marking the circle, but you MUST have the skirt at the proper angle to the base/wall ring surface or your measurement will be incorrect.
