Prime-Line TH 23076 Entrygard Dual Arm Left-Hand Casement Window Operator with Stud Bracket – Repair Broken Windows (Single Pack)

They are a little pricey, but this replacement saved me a lot of money compared to calling in a window specialist. Installation is easy and straightforward. Here are a few tips: 1. Remove the handle and wood or plastic bottom sill that covers the gear (mine was attached with two wood screws) - take a picture of the mechanism to make sure the model matches. 2. Make sure you get the correct right-hand or left hand model. 3. Have a dust pan brush or vacuum handy to clean out leaves and dust that collect around the sill. 4. An extra short rail is provided, but I did not need to replace mine. With a flat screw driver, just unclick the old slider sleeve and click the new one into place. The other long arm simply slides into the long rail from the end. 4. Be careful! Working around open casement windows can be dangerous from high floors. Now that I have learned how to install one, I'll be ordering more for the rest of the house!

When this broke a week ago I was worried. I was sure I wouldn't be able to find this for a 25 year old window. I think I spent an hour and half reviewing options and finding the solution. The installation was much easier than expected. I was concerned I wouldn't be able to get to the screws, but it turned out the wood strip over the mechanism was easy to remove and reattach when done. My window was installed in 1995 when the house was first built (window brand: Kolbe). Product appears to be of high quality and if I have to do any more of these I know it is easy to do. One recommendation, if you do have any of these, cleaning/lubricating any non broken ones would be recommended (pop off the cover, clean, lubricate, and open/close the window to lubricate the gears).

If your home has average size, side-open, crank-operated casement windows then it probably uses this device or something very much like it. I get the impression that this brand and model (whether right-handed or left) was used in a LOT of houses in the US. That explains my review title. If you have a broken window crank "operator" that matches this one, in size and method of operation, then yes you can replace it with this fairly easily, and it will work just fine. Numerous online videos explain the replacement process. You definitely need a screwdriver, and you probably need a pry bar and/or putty knife. That’s about it. A beginner should be able to do it, and a competent handyman can do it fast. We've replaced two, and they work fine afterward. I believe one of them was only about 10 years old, but I don’t know if it received rough treatment. But we've had no problems after 3+ years of the ones we installed. Not worth worrying about, since I don't think there are many competitors. My biggest complaint is that these have skyrocketed in price. Here today they cost twice what we paid in 2020, and other vendors charge even more. This has nothing to do with inflation. It's a very simple device that is mass-produced. I won't knock off a star for that, but I'm tempted...

I am a DIYer and I had bought a home and this window was broken for 2.5 years. I tried a few hacks but they also broke (including the hanger hack. So, bought the one that resembled and measured exactly and this fit nicely. Can’t believe I waited so long. It took me 7:45 minutes. This was after spending two hours searching for reviews, looking at YouTube videos and it was already opened and revealed so I could match the part when ordering. It was a very easy fix once I realized what I needed to do based on illustration direction and YouTube videos. Perfect fit.

I had to replace some operator which failed en masse. I purchased 6 total both right hand and left hand versions. The old operator lasted about 20 years. The operator failed were one facing prevailing wind (south and west facing windows). Other windows' operators are working just fine after 20 years of operation. Only semi-gripe is that the screws that comes with the operator is short 3/4" size, and the number of screws provided does not add tot he available counter-sinked holes in the base. I assume that the intention is that not all the hole are required to be used. However, I replaced these screws with 1-1/4" brass screws to give it more weather resistance and more secure attachment to the base. This is stop-gap solution, since I will probably replace these windows within 2 years. But, for now these replacement fits exactly the hole location and sizes. It is a perfect replacement. Replacing the operator takes about 15-20 minutes which includes the removal of wood sill cover. It is a quick drop-in replacement part. Recommended.

Great replacement. Have used these before. 10 Minute install...

After 40 years of cranking, the shaft in the worm gear snapped on my Semco casement window. I was thrilled to find this item to be a perfect replacement. No issues at all. Even the screw pattern matches. The original arm was brass color washed and this item is grey, but no one else would notice it.

The mechanical crank operator on my 25 year old Moss casement window finally bit the dust. It was on the most highly used window in the house and it would be unfair to expect it to last forever. The shaft and worm gear assembly retainer broke free rendering the mechanism useless. This left me with a window that could neither be opened or closed. My fear was that finding a replacement part for such an old window would be futile. I was wrong. After a relatively quick search on Amazon and inspecting photos, I found what appeared to be a direct replacement. In fact, It was a perfect fit and saved me from having to order and install a new window. Mission accomplished!
