Parts to fix my casement windows exposed to salt water
2nd part - more photos.
Hello,
It sounds like you're looking for replacement hinges. Take a look at the 36-004-10 in stainless steel, which will hold up better in salt water conditions. Just make sure to confirm the 10" base that attaches to the window sill matches yours. Thanks for posting!
It does look like the 36-004-10 would be our best matches for your hinges as long as it has the same 10" base. You should be good to go as long as you replace the top and bottom hinges at the same time.
If you need the operators as well, see the 39-220B and 39-221B shown in your first batch of photos, as well as the related parts shown on this page.
Your second batch of photos shows the dual-arm Encore operators featured in our video below. The determining factor would be the fitting attached to the long arm.
We can't be sure of which operators you need without seeing the fitting attached to the long arm removed from the sash track.
As for the guides in your last photo, those are from the hinges that we recommended the 36-004-10 to replace as long as the base measurement matches yours. Keep in mind that the operator and hinges are separate pieces of hardware.
The image that you provided below matches the 39-529 used with the 39-253RB and 39-253LB.

The design of the guides in your most recent photo appears similar to the fitting used with the 39-438B and 39-439B you mentioned but it is also a design used for many hinge sliders. Since the photo of your operator guide does not match the guides you show uninstalled and I see rust on the base of your hinge where the slider would fit on the track, I am left to conclude that the guides you removed must be from the hinges. The 36-004-10 we mentioned is a slightly different design but they are very versatile replacements as long as the top and bottom hinges are replaced at the same time.
As I mentioned, our hinges are quite versatile and have worked as replacements for different variations of this type of two-bar hinge as long as they have the same 10" long base. The 36-004-10 comes with two hinges, one for the top and one for the bottom of the sash. If you decide to give them a try, our return policy can be found here. We offer the 33-115 screws but commonly used with these hinges but make sure to confirm the length matches your original screws to avoid hitting the glass in your sash accidentally. Pricing for each part can be found on our product pages.
