I ordered the Pella Screen Insert Latch Pair, #70-216, but it did not fit. I think I need an older style that may be referred to as a "knife" latch. Do you carry these? PAT NO 2,776,002

Take a look at our 70-172 and 70-174 and see if either of these pairs could work for you. Make sure to carefully compare dimensions to your own hardware.
