This is exactly what I was looking for to use for my bay window in the kitchen. Although the instructions say to drill a 55mm hole with the side clips it is too tight to install. a 57mm works much better. Luckily I only drilled one hole and tried to fit and adjusted to the 57 for the others. Otherwise it would be 5 stars.
