BSI 2470 - Block and Tackle + end guides

Question

Hello,

I need a replacement block and tackle. Below are the specs for my current equipment:

Markings: BSI 2740

Metal channel measurement:
28 inches long
9/16 inch wide
10/16 inch deep

The closest item I could find on your website that looks most similar to mine is:
28" Series 385 Channel Balance - Product Code: S385-28

The end guide with the spring attached does not have a winged tab on my equipment (compared to S385-28). I'm not sure if they broke off or if they were not there to begin with. This is the case for the block and tackle for both sides of the window.

Please view the provided photos, and confirm whether or not this is the correct part.

Thank you.

Hi Khanh,

Thanks for posting! Your channel balance appears to be closer in style to the S350-28 Channel Balance. Like yours, this balance is made with a wingless top and a winged bottom shoe.

Please let me know if you have any questions.
