Everyone who has wrenches, both metric and standard needs to buy two of these Craftsman Wrench Organizers. The hold the wrenches real good. They are organized by size so makes grabbing the one you need easy. Also has a handle so that you can carry all the wrenches to your project if you are unsure of the size you need. Great investment for under $10
Thought it would be a great tool but there is two problems, some wrenches are too short for holder and some are narrow and fall out of the holder. No way to adjust the holder so out of luck.
Very handy storage for your wrenches. Keeps them in order so you can easily find the correct size when needed. Fairly inexpensive and on sale a lot. Can also mount the organizer to your wall or pegboard without the wrenches falling out.
