Pivot Shoe and Tilt Latch

I need to replace a broken tilt latch for a patio window, and I believe I have found the right part for that item (26-393B). I also need to replace a couple Pivot Shoes but have not been able to identify the exact item. The closest I could fins was #15-192. The pictures attached are of the shoe and of the sticker on the window. There is no brand name so I am having trouble zeroing in on the correct parts. Can you guide me to the right parts, both the latches and shoes?

Emily,

Thank you for your responses.

The tilt latch looks almost exactly like #26-393B. (pix below with full window and window locks and tilt latch)

And, unless I am mistaken there is no counter balance or coil spring. I think that this is just a friction stop/hold type of setup. I am not super experienced, but I did not see a coil spring or, for lack of a better term, twist/spiral spring in the window. It seemed like it was just held in place by the shoe it self. This is going to sound so dumb, but I don't hear any "sproing", "tinking", "scratchy" sounds that would tell me there is some weight relief going on.

I could not find a brand name so that is why I sent a pix of the label on the side.

The window is at my mother-in-laws house so if I need to look for any more clues for you I will need to check it out this weekend.

Thanks so much for your patience.

Emily,

I appreciate your quick response. Thank you.

When I get back to my mother-in-laws house I will compare the dimensions of the tilt latches for the best fit.

Now, the pivot shoe: I asked my wife, who is at the house, to feel and search for a flat coil spring running along the inside of the channel and above the shoe for a block or a jig holding a coil spring and she could not find one. And there was no evidence of a spiral balance. Yes, wierd. I will send her a link to the YouTube video you sent me so she has a better idea, buy my wife is a very smart lady and when she looks at the video she will be able to tell if she missed anything.

If you can be patient with me here is what I would like to do for next steps:
- Please keep this case open, I need some time to get back to my mother-in-laws house to collect some details.
- Now that we have talked I will dig in deep on the window
- Remove the shoe completely to clearly identify if there is any spring or counter balance attach.
- Take clear pictures of the shoe along with measurements.
- Clear pictures of the channel and window path for you to be able to analyze.
- Can you accept video's? If so, I can shoot a quick scan of the window so you can stop and start to help with the analysis.

Please understand if we can identify the right parts I will buy a few sets, because these have been baking in the ruthless Florida sun for years and are getting pretty brittle.

I will have a computer at my disposal and my cell phone so I will be able to send the info, pix and vids from the site.

Thank you again and have a great day.

UPDATE:

Emily,

Like I said, my wife is very smart and I am glad she is helping with this. If you look at the one picture you can see a double wheel configuration half way up the channel. I absolutely missed this. If this configuration is familiar to you, let me know. When I can get to the house this weekend, I will look at this very closely and make measurements and understand the configuration better so I can describe it to you.

I still want to follow my previous steps so we can find the parts needed.

Thanks again your patience.
