wheel for sliding glass door

A handy person from woodcliff lake, new jersey says:

I'm hoping to get replacement wheels for my old sliding glass door. The marking on the wheels are Del Mar engineering, with a patent number.

The two photos I hope are self explanatory. Of course I hope that you have a couple of them.

Hey, Sid. This looks an awful lot like our 81-033. Check it out and tell me if you agree.
A quick learner says:
Tom, I'd have to agree. It sure looks a lot like the original. I'll place order and give it a shot. Thanks for your help! Sid

I was happy to help, Sid. Let me know how it works out, or if you have any questions in the future.

81-154 should also be a beefier option.

Be aware, I just noticed that 81-154 does not have the same rail lock tabs. I'm not sure what keeps it in place because I don't run into either of these in California.
