Double roller assemblies for patio door

A home owner says:
I am looking for some roller assemblies for a 35 year old patio door. It looks like the manufacture of the door was Associated Dallas Laboratories (see pics) but the roller assem.says Del Mar Engineering. The dimensions are very close to your 81-018. It has 1 1/4 inch steel wheels, it's 11/16 thick, 5 3/4 between mounting holes, 1 7/16 tall. Is 81-018 the correct replacement?

Also, do you carry any weather stripping products for like where the two doors overlap?

I agree, the 81-018 looks like a close match. Just make sure that all the dimensions are the same. As for the weatherstripping, it's harder to say. Look at our 58-056 and 55-170 and see if either of these can work.
