Block and tackle balance

Question

I believe I need a series 351 with a 19-002 top and a 15-002 shoe. They are stamped with 1640 and 2840. Please advise. Thank you for your time.

Thanks for posting! If the depth of the shoe is 1", then I agree. Our 15-002 is probably the best choice, which means you're dealing with the Series 351 balance.
