Hello, thank you for posting! 

Your roller resembles either our 23-047 or 23-031 depending on the offset. Please compare the dimensions listed on the product pages to determine the correct fit!

Thank you, Lauren - I take it the "LB" logo wasn't helpful.

Some more info I should have included: the bracket is 3/8" offset, so neither of your suggested brackets would work. The wheel is 3/4" diameter and 1/8-3/16" thick.

I originally purchased the Johnson replacement roller assembly pictured below. The offset is correct but the wheel diameter was too big at 1", and the wheel seemed too thick at 3/16-1/4". The old wheel I'm replacing seemed a thin 3/16".Hope this helps, and thanks again.

The LB stands for Lawrence Brothers Hardware, unfortunately they discontinued their closet door hardware. The #23-031 & #23-047 is a replica of their original closet door rollers. The nylon wheels are 3/4" and the #23-031 has a 1/8" offset and #23-047 has a 1/2" offset. Unfortunately we do not carry a replacement with a 3/8" offset.

Thanks, Lauren!

I'm going to order those two now and make one of them work.

I have the exact same original pieces. Since a 3/8 inch offset isn't available, would the best option be to get the 1/8 inch offset for the outside/front doors and the 1/2 inch offset for the inside/back doors?

Hello, thank you for posting! 

Unfortunately if the offset is 3/8" we do not have a suitable replacement as these measurements are exact for the roller to work correctly. We cannot guarantee if you would be able to adapt your door to use the 1/8" or 1/2" roller. I apologize that we could not provide further information.

This post and thread was very helpful. I have an LB No.452 (tandem wheels) with a 1/8" offset that I need to replace. I have not found any replacement parts and now I know why since they are discontinued. I would hope that I could use two of the 23-031 to replace the one unit I need replaced.
