Hello,
I agree that your photos resemble our 15-192 pivot shoe, which uses our Series 170 and Series 171 Coil Balances. For a 25-pound window sash, I would recommend using one S170-406 and one S171-406 on each side of the window.
The corresponding covers and screws can be found under the related items section of the coil balance product pages. Thank you!
