Almost perfect

Only reason I gave it 4 stars is, they aren’t exactly 90 degrees. I used them on a work bench and I could shim them to be right. If these were a critical component they would be off.

Is not square when in the locked open position.
Size: 24 Inch, Size: 24 Inch
Purchased 2 sets of these to make a folding wing on my workbench. Didn’t expect great quality but did expect 90 degrees. Installed and the end of my 27” wing is 25mm higher than the fixed end. Measured bracket and hypotenuse and ran some quick cosine to discover the bracket is actually 91.286degrees. There is zero adjustment capability on these. Buyer beware
