Hi..I just placed an order for the part attached..two nylon roller wheels side by side. Did I order the right parts? (part # 81-143?)

Thanks for posting! It looks similar, but I can't be certain without knowing more detailed dimensions.

For future reference, I recommend that you do not purchase any hardware until you know that what you're buying is correct, just in case. It's possible that the order you place will ship out before we can even see your Discussion!

Carefully compare the dimensions we list for the 81-143 and see if they're the same. If not, let me know exactly where they differ and by how much.
