perfect replacement for existing window cranks
Our house is twenty five years old and our window cranks are wearing out. These window cranks are the perfect fit. They are not only attractive but they are easy to change out and are quite durable as well. The white color matches our window frame color perfectly. The fold in easily to accommodate the wood blinds on the window. The price is reasonable as well. You will not be dissapointed.

Plastic adapters are absolute trash
If you're lucky, you can get one to five cranks of a window with one of these.I followed all of the instructions to apply this product to three different brands of window, and the plastic inserts shredded to pieces very quickly.The supplier likes to say "the set screw is required for proper operation," but that's NOT what the set screw on most windows is for. The set screw is meant to prevent vertical movement of the handle so that it does not come off of the post it is attached to. It is not to be used for securing the handle during rotational movement. The interlocking "teeth" on the post and the handle are supposed to be doing that.As the "teeth" on this product are thin strips of trash-bag quality plastic, they don't do the job.I suppose, if you had brand new, very light, very-well greased windows, these could last six months to a year, but in a real window, in a real house, in the real world, these are just useless toys.

Does the job!
Good, does the job. But the plastic inserts eventually will strip in a short time. Especially if used frequently!

Needs some redesign
The product overall is good but with it being a universal product the insides are plastic and they strip out fast

Perfect
I’ve been trying to find new cranks for my old windows for years. I was so happy to find these I grabbed the set and they came in rather quickly. They have multiple fittings which was great found the right size pretty quick! They work so well I got white ones and they go well with my living room color! They seem to be pretty sturdy and love the fact they fold down

Bad paint finish
Too rough and poor quality to use. Will throw it away and not order more.

Work with almost any window !
Tons of different size adapters make installation very easy and should adapt to almost any crank out window. Used with some older Andersons that the originals were stripped out and won’t tighten and all other replacements did not fit. With these handles and some wd-40 in all of the mechanical areas the windows are now opening and closing beautifully.
