Prime-Line H 3785 Spiral Balance Pivot Lock Shoe, 5/8 In., Tilt Window (1 Set)

It fits my windows well. The only difficulty I encountered was that the size of the blue bushing for pivot bar insertion just matched the pivot bar. So you have to be patient to twist the opening of each replaced lock shoe (on both side of the window) to the right angle - so that both pivot bars can fit in. My old lock shoes appear to have a slightly bigger opening, which makes the bar insertion easier.Most video demos on youtube suggested to cut a small piece of the groove edge on the vinyl window to take out the old lock shoe and put in the new one. However, I followed a suggestion from internet long ago by using a heat gun to soften the groove edge for the task. It worked out pretty well. After cooling down, the vinyl returns back to solid again. Just have to make sure it stay straight enough after cooling down - for the smooth movement of the lock shoes.

This lock shoe worked well. You may have to cut part of the channel for the shoe to fit. A dremel will do the job.

Replaced a few broken glides. After doing the first window and figuring out the process the other windows were easy to fix. Saved $100s of dollars for a few hours of work. Good quality part, very happy with the results.

good part

One of my windows was sagging and once I looked in the tracks, I realized on the of shoes was completely broken. I measured the track and found these replacement shoes. Clipped the vinyl back to fit the shoe (easier said than done), went to put the window back in, and realized the bushing was significantly smaller than the tab on the window. Apparently there are multiple bushing sizes and there wasn't any mention of the size of the hole on the product description. So what I ended up doing was removing the bushing completely. I lost the ability to lock the shoe in place with the window out now, and I have to be careful it doesn't shoot up if I remove the widow again, but it supports the window properly now and it doesn't sag anymore.

Easy to install, I’m glad I was able to find it and not having to replace the entire window, I would definitely recommend it to anyone

This was a perfect fit for my 20 year old Patriot windows. Tricky part was removing the old and installing the new. A quick search on YouTube showed me how, just need to cut a piece of plastic off at top of window, slide it up, pop it out and pop the new one in. Easy Peasy.

Garbage. Absolute Garbage. I've had them installed in my window for 6 days and they just broke. I should have known after noting the poor build quality where the metal insert pops out with the slightest provocation. Very disappointed.
