All Erva pot rings were developed to fit Pennington Brand clay pots perfectly. A 6" Penningtion Pot fits perfectly into the PR6SDX 5.25" actual exact Inside Diameter. Other brands vary slightly but will also fit in the ring. 

Erva's SDX Series pot rings feature a heavy duty bracket with keyhole cut outs - which allow for quick and easy removal of the bracket at the end of the season. Erva pot rings are all built to an exacting standard with extra heavy duty components and are guaranteed not to sag under the weight of a fully hydrated pot.

The sturdy ring is made with 5/16" wire. The bracket is made from 12 Gage steel, 1" wide. Powdercoated back. Two Black Zinc coated #8 x 3/4" Screws are provided.

Made in USA with all American made materials.
