Casement Window Crank Handles

Common types are the following

• Female Spline


• Female Hex


• Male Hex

You can see the example in the picture.

After you have determined what type of spline you have, you need to know the size. Sometimes, casement window manufacturers use a specific size of spline for their brand and sometimes not. The best way to be sure you get the right size is measure the bore as shown in the picture.

Another measurement you may need to know when looking for the right casement window crank replacement is how far the crank handle projects. In tight spots, this is a good number to know. It could mean the difference between a crank handle that actually operates and one you don't have enough room to turn. Look at the picture for a example of casement window projection.

A folding casement handle cranks the window open or closed in the same way original-equipment operators do, but then it folds out of the way when not in use! It's a sure way to avoid ruined mini-blinds or curtains, or ripped pants pockets, and it's easier to turn than small, wing-shaped replacement handles.

When choosing hardware for your casement window, consider any potential interference that may hinder easy operation. A compact T handle would be a perfect fit for a window you intend to adorn with blinds. If you are looking for a design that deviates from your standard casement handle, a T-handle is a viable solution.
