Dome ring apron collar

Dome ring apron collar
The dome ring apron collar is made of polyester and glass fiber. The collar prevents rain from blowing in under the rotation ring.

The dome ring apron collar is made of fiberglass-reinforced polyester. It consists of five segments. There are pre-drilled holes for stainless steel countersunk screws and bolts that fasten the segments securely to the rotation ring. Later, the bolts holding the dome in place will extend through the apron collar and rotation ring.

 

The joints between the collar segments are sealed with a polymer sealant.
