Thank you for your recent inquiry regarding this item from Prime-Line Products. Unfortunately there is not one shower guide that is standard to all shower door systems, and there is no sure way to determine the correct replacement guide without removing one and matching its dimensions to those listed online. Shower door manufacturers can often use more than one design within a given series or product line used over the years, making it sometimes difficult to provide an exact match when relying on manufacturer name and series alone. I would encourage you to visit Prime-Line’s website to find the correct replacement guide your shower door requires. Please also feel free to contact Prime-Line Products directly where a Customer Service Representative there can better assist you with your inquiry. You may also email us photos so we can visualize precisely what you are inquiring about.
