A handy person from New Jersey says:
I have a Silverline casement windows 70NCW1 and it came with standard hardware (marked 31858) in attached pictures, but i need an Egress hardware to make it open at the edge instead of sliding closer to center. Any suggestion what will be egress hardware for that window?
