If your Andersen casement window crank is broken or missing, this 2-pack of T-handles is exactly what you need! These are designed specifically for windows with 3/8 inch shafts - the standard size for most Andersen operators. The T-shape is super smart because it doesn't bump into blinds or curtains when you're opening and closing your windows. Made from high-strength metal with a white painted finish that resists rust and corrosion, these handles are built to last through years of use without fading or bending out of shape. The butterfly wing nut makes installation a breeze - no tools needed, just hand-tighten and you're done. Each handle measures about 2.36 inches wide by 0.82 inches high with that perfect 0.38 inch (3/8\) bore diameter. They work with Andersen windows and many other brands too, so if you've got casement windows with similar operators, these should fit perfectly. The clean white look actually makes your windows look more modern and put together. If by some chance they don't fit your specific windows, no worries - we've got a solid return policy. These are one of those simple replacement parts that make a huge difference in your daily life. No more struggling with broken window cranks or missing handles!
