Parts Desk Insights
Best use: Replacing the specified washer during compatible trim-cylinder or anchor-pin service. Common mistake: Assuming similar-looking trim hardware fits across drive generations. Sizing and fitment: Compare the approximate 33/64 in. inside diameter and exact part number to your drive's anchor-pin diagram before ordering.
