The plastic pieces shown here come from our kitchen light fixture.The plastic fractured when I was replacing some light bulbs. I was wondering how the parts were originally installed, considering how fragile the plastic was.
The answer came when I picked up parts at a local hardware store. The new plastic is much more flexible than the old plastic. I was able to bend the plastic to fit it into the shopping cart. According to the big print on the label, this material is "virtually unbreakable." The fine print says that the warranty is good for 10 years. The original plastic was probably installed when the house was first built, 16 years ago. As the plastic aged, it became more fragile.
