Sliding glass door tandem wheel replacement

Hey there,

Thanks for posting! Your Del Mar roller looks a lot like our 81-138, which does match your existing measurements. The only difference is that the wheel diameter on this roller is 1-1/8". Since there is only 1/8" of a difference in the size of the roller, you should be able to adjust the roller to accommodate for the difference in size.

Take a look at the dimensions below and see what you think.
