Marine sliding door rollers

A home owner from Stratford Ct says:
I'm seeking to replace the two bottom assemblies/rollers in a marine sliding door application. I believe the original item is a PE Delmar, SF1.

It has a 1.25" dia nylon wheel, length 1.92", height 1.04 width .052

Can you help?

Thank you for your patience in this matter. The closest match we were able to find was our 81-090. However, you would have to swap the wheel out with either our 81-229 nylon or 81-241 stainless steel. You should be able to re-use the axle on the 81-090.
