Tandem Wheels for Enclosed Lanai

A home owner from Honolulu HI says:
Name on the side of the wheels is

Del Mar Eng Co.
Long Beach Cal
PAT. 3,670,35

I have looked on line but can't find Del Mar Eng Co.

Anything you can do to help would be great.

I need 4 of these tandem wheels.

Thanks for posting! Take a look at our 81-052. The dimensions of the housing seem to be the same as the one in your photo. The biggest difference is the wheel, which is 1-1/2" in diameter on ours where yours is 1-3/4". I believe you should be able to adjust the rollers to make up for the difference, though. What do you think?

i ordered the 81-052 part. the housing fit perfectly. exact match with 2 small exceptions. the housing on 81-052 had two little wings - one on each side that we had to cut off with a powerful dremel to fit into the base of the sliding doors. other exception was the pin that slides up and down sort of at an angle also had a head on it that added a small amount of width to the housing but it was negligible. otherwise 81-052 was a great fit and my lanai doors work great. so happy! no more straining my neck and shoulders trying to drag the doors open and closed. mahalo!!
