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

You'll flip over the added countertop!
Good product, seems well made. Installation was simple enough. It gives us a little extra counter space when needed. The only issue is it blocks the entry a little when flipped up in our RV. Just look before you step in.
