Balance has Unusual Bottom Shoe

I am looking for a replacement Balance.
The number on the balance is 13-3, and I can see BSI stamp.
I am not sure which balance on your website can be used because I cannot find the exact same bottom guide on your website.
Can you help identify this balance?

Thanks for posting. We can help you replace this balance, but it will have to be a custom order. Could you confirm the length of the metal channel is 13-5/8", not including the end attachments? And how many of these balances do you need? Once we have this information we will email you a special order link and price quote for the quantities requested. Thanks.

It looks like the metal channel is 337mm/13-1/4" long, not including the plastic end attachment on both ends.
I would like a pair of this replacement balancer, so two will do.

Perfect, thank you! I'll have my colleague Tom email you an order link and price quote right now.

Thank you for the custom order link.
Before I place the order, I would like to verify that this balance comes with the plastic attachments on both ends that can be used in the original window.
Please let me know.
Thank you!

Yep, all of our balances come pre-assembled and ready to install out of the box.
