Look, it's just straight brackets, no need to worry. Plus, they're great! The price is perfect and 30 pieces are enough for a big DIY project. The screws are the perfect length for use in wood and are well made with the one exception I found in my bag. The brackets themselves have a good surface finish and countersunk holes so the screws don't protrude when used properly. Bonus tip: With a pair of pliers or something similar, you can easily bend these squares into vertical brackets with little effort. Strength. They are still strong even though they can be bent. This allowed me to use them twice in different situations for the project, so their value is great!
