Channel Balance Top, Acorn

Hi 2230 is inscribed. Looks similar to series 710 on one end, but the other end appears to to be more of a horn shape- terrible description, sorry but correct word escapes me. Would also be looking to replace the connection points on the actual window

We are also needing ballast for 2 windows the number on this part is 28-30 If there is a right and left We need 2 sets Please let me know cost and availability All our windows are the Acorn Athern brand Number 2830 Window is 58 inches tall 31 and a quarter width Ballast is 29 7/8 - 30 inches ... (cont.)

If you could direct me to the correct part for this metal window this balancer should not have a hook in the back of the block and tackle if I'm not mistaken

Hello, can you please tell me if you have any channels with the Acorn top and bottom shoes in inventory, or would it need to be a custom order? I'm looking for a 2840. Thanks

I am looking for replacement sash balance for an iunknown window brand. They are older and have no Markings. The balance is stamped 1640 any ideas on parts with the ends needed ?
