We lost our original pegs during a move and picked these up as replacements. Wow, I wish I'd had these the first time around! Far superior to the "stock" pegs, these are strong enough to hold the vertical braces in place while the rest of the shelves are assembled. Made things 10x easier!

I lost some of the connectors for my Costco purchased shelves (3 sets). I ordered these as replacements and they are sturdier and better made than the original pieces. Would definitely recommend.

These were very difficult to install. The parts are not formed well and I had to bend it to fit it in. When I tried to remove them, they broke.

I would've rather they fit a bit easier, but they ARE stronger so there's a trade off. Overall I'm happy.

During the move many of the little black pieces went missing. I got these thinking they would be the same, oh no, they are much snugger and longer, over all these are better in every way, if I buy another shelf, I will not use the pieces it comes with, I will order more of these. They made building it easier (connecting the two corner supports together was simple with these. Connecting the corner supports with the supplied pieces, they were popping off and just a mess and troublesome until you got it together, these were simple to hold it together while putting on the brace shelf for the middle connectors.
