Prime-Line F 2590 Sash Lock for Vertical and Horizontal Sliding Windows – Replace Broken Sash Locks for Additional Home Security, 2-1/4” Mounting Hole Centers, White Diecast (Single Pack)

The Prime-Line F 2590 Sash Lock was a perfect replacement for the latch that came with my home's vertical sliding windows. One of the original latches was bent, and threatening to shear away, and this latch worked perfectly. The dimensions were exactly as described, it fit so exact that you wouldn't know it was a replacement, and it even latches better than before. The window closed and latched securely. It is a nice value for the money, and I would definitely buy it again.

Very easy to install, thank you!!!

A direct-fit replacement for SUNAIR Aluminum Products latches. TIP: clean your tracks and shut your windows firmly before locking and you'll have less problems with broken latches. Note: there is no "right and left" latch for these windows; simply invert the latch as needed. Our home came with SUNAIR latches - all opened left except one - when I removed the broken original latches the sole window which slid to the right had the same latch as all our left-sliding windows. All the SUNAIR latches in our new home broke within the first 6 months - the building stores were still stocking SUNAIR, but why would I buy them again? So we limped along with 1/2" PVC pipe wedged into the tracks (bottom AND top) for the last 20 years. These latches are marginally stronger than the originals, but the flaw is not with the latches, rather it's the way the latches interact with the window frames. I gave these 5 stars because they fill my need and were inexpensive - they were exactly what I expected when I purchased them. The only way to get a better latch on windows originally equipped with this style latch would be to completely re-engineer your windows with 2-piece latches and hope your refitted latches covered the original holes in the frames. Go with these for economy and function. Don't force them - slam the window and they'll latch easier without breaking off in your hands.

I have sliding windows in my three bathrooms which I believe are made by International Window Corp. (IWC). One of the plastic lock assembly levers broke recently and I ordered this part thinking it was an exact replacement. All of the critical dimensions seemed correct: the 2 1/4" hole spacing, the 3/8" projection of the locking arm which keeps the window from sliding open, the 3/4" width and the almost 3" overall length. What I failed to notice was that the holes of the original part are offset from the centerline of the assembly. In the attached photo, the original lock assembly is at top and this Prime-Line F 2590 assembly is below. With the screw holes in the center of the assembly and using the original holes in the window frame, the projection is too far away from the fixed window frame and thus you can't lock the window.If you have a window sash lock with the offset mounting holes, then Prime-Line F 2594 is what you want. I'm returning these and ordering the 2594s.The overall craftsmanship of the lock assembly is good. The metal frame and locking arm is certainly more robust then the original plastic. The metal spring arms inside the frame allows a little bit of play of the lever when it is in the unlocked position, but then again, so does the original plastic one.

This was a good value for the money and works well. The durability is good a works well. Gives a good sense of security.

We had a window that had broken latches. I came onto the Zon and quickly found these replacement latches, made sure measurements matched. Which is a great listing image, to ensure they fit properly. Took 2 minutes to replace, and they latch perfectly. Great product and quick delivery.

1959 Original latches were aluminum.Disappeared/broke (?) before I bought the place 25 years ago. Wood shims kept the window from opening.Fit perfectly and the window can be lowered!

Good quality and a solid latch. As advertised.
