I haven't used them yet. I bought them from of @ocgrant as he ordered too many. Once I removed my door I was able to clean my existing glides and tracks, and still have the new ones in my stock for future use.
Hey Jeff. I know your slip, and marina well. I don't know which model Sea Ray you're considering, but I would be more concerned with entering/exiting the boat safely from a short pier. We've had times while traveling where we get stuck with a short pier and need to stern in just so we can...
I had mine made in a custom length by Tig Vision, however I believe they have standard lengths as well. The quality is excellent, and exceeded my expectations.
