Identifying Correct Part

Question

The pictures are of a 31" Block and Tackle Balance (non-tilt). The stamp pictured says...

(02/05) UNIQUE 30-C-30

I have a number of these I need to replace. I am not sure if they are all the same size. For bulk discount, do they all need to be the same size?

Thank you for any information you can provide.

Thanks for your photos. Based on what I see here, you have either our S351-31 or S390-31, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
