If you are tired of the traditional metal hooks that are loose and try to unhook with you try to remove whatever is hanging, then you're ready for these. The upper hook into the top hole is curved according to whether it's a thin, metal/plastic pegboard or the traditional thicker masonite (so be sure to order the correct type). The lower straight peg is held firmly in the board by a plastic surround that snaps into the hole. Problem solved.
The hooks are readily removed for repositioning if you need to reconfigure. I liked having all the same hooks as 2" straight hooks are right for 98% of my hanging items. Great product!!!
