Thanks for posting. I agree, this looks like an S770-32 with a stamp option of 32D--but with a Rivet in the Top Hole, so that it can connect to the window jamb using an S-Clip like the 19-029 or 19-030. We'd be happy to make Series 770 balances for you with a rivet installed, via a custom order. I just shot you an email with a custom link to order a pair of such balances. if you need a different amount, just let me know. Note that the S-Clips are sold separately. |
