When installing plastic roofs which allows sunlight to pass through inside the house on daylight (don't know how it is called), I recommend that you double it instead of just one so it won't easily break even if it is hit with something outside the house. I installed two (doubled) on the roof of our comfort room a long time ago, seven years probably and up to now it is still intact.
Use a plastic wire or cable as big as the ones that got broken to replace the rusty metal handle of your old pail or balde.
If you had a problem with your doorknobs locking you in or out of your rooms and is already tired of installing new ones
