Hello, I'm looking for a replacement casement handle. Windsor is stamped in the front and the back looks like it says either 4 or 14 and 45054.

Thank you

Thanks for posting. I think we can certainly help you find a replacement crank handle. First, can you give me the diameter of the hole for this handle? A picture of the operator it attaches to would also be helpful. Many thanks.

Bob, thanks for your help. The hole is roughly 1/4 inch in diameter. It is difficult to send you a good picture of the actuator because the counter covers all but the spline.

I attached two pictures. One shows how the angle of the handle is critical due to the distance from the spline to the counter top

Unfortunately, we don't have a handle with a 1/4" hole diameter. I've actually never seen that size before. Could it be something more like 11/32" or 5/16"? I would double check just to be sure. It's important to be as precise as possible. I'm afraid estimates won't help when it comes to this measurement.

Hi Bob, it's 5/16

Thank you! The only handle we sell with a 5/16" spline in this style is our 39-274. Look it over and see if you think you could use this on your window.
