Hardware for Milgard series 3510 Casement
Hello,
Unforutnately, we do not have your exact replacement for your Roto casement hinges. Our 36-048 2-Bar Hinge Set is often recommended as a replacement but you should expect to drill new installation holes. You'll need to be careful not to drill too far into the frame since you could potentially hit the glass.
Keep in mind you will need to to replace both the top and bottom hinges to ensure the integrity of the window's function. This set can be used for right and left-handed applications.
As for the crank assembly, see the Roto 39-091 and 39-092. If you also need to replace the crank handles, we offer the 39-224 Fold-Down Crank Handle or the 39-230 White Handle with Set Screw.
The link arm for these operators was discontinued, so you will need to detach the original aem from the operator base to reuse with the replacement operators. Thanks for posting!
