The flange width has no impact on the size of the dome.
Our stock plastic hemispheres are fabricated from 1/4″ thick, clear acrylic. As the plastic is stretched to make the hemisphere, the leading edge of the hemisphere will shrink to about 3/16″ thick, and the apex (top) may be as thin as 1/16″. Hemispheres ordinarily come with a 1.5″ flange. For Example: a 12″ hemisphere with a 1.5″ flange would have an overall outside diameter of 15″ (4″ hemisphere comes with 1/4″ flange). We can custom size your flange or ship the hemisphere without a flange. Please specify when placing your order. If you are planning to make your hemispheres into a sphere or globe, please let our salespeople know in advance or visit our plastic spheres page for more information.
For orders of 25+ hemispheres, please call us at 909-930-5535 for the lowest pricing on both the hemispheres and shipping.
