Gibraltar TSS Felt Gasket Set of 12, Junk This is only for the gaskets for Gibraltar TSS plates. The third from the right in the bottom row has a different gasket shape (for longer plates). They have adhesive tape, so peel off the backing paper and stick them to the plate for use. I think they can be used not only for Gibraltar plates but also for other companies' products. How about them as spare parts? Please consider them as junk parts that have been stored in a warehouse for a long time.
