Designed by: Steven J. Orlansky, Waterbury, Connecticut.
"Hover" is what it is called and for good reason. Orlansky's aluminum grommet has a unique feature: the edges of the cap are very wide, stepped, and substantially overlap the diameter of the hole. Since one cannot see the edge of the hole under this brim, there is no need for a liner. Can fit two sizes of holes: 2" or 2 1/2" diameter.
Note: Price varies by finish.
Finishes: Satin Nickel, Polished Aluminum, Matte Black & Satin Chrome.
