Lisle LS40130 1/4" 26PC SOCKET HOLDER BLACK

It can fit one socket just fine, but if you put in a socket that is 1 mm smaller in the adjacent slot, it won't fit! Apparently, the slots are sized in 1/16 inch (1.5875mm) increments rather than in 1mm increments.

I have the Red Lisle 3/8" Magnetic Socket Holder and the Black Lisle 3/8" Magnetic Socket Holder. Purchased here by Wifey. The magnet socket holders look great and hold the entire set of 3/8 shallow and deep sockets. The back magnet will hold the organizer to the side of the cabinet with no problem. The Shallow sockets fit and hold great with no problems. BUT, the deep sockets are to heavy for the magnet to hold them well. If you carry it by the handle the larger sockets fall off as you are moving it. The only reason I wanted the organizers was to have the sockets on one rail to take with me. Pretty much makes it useless for what I wanted them for.

These work really well for organizing, storing, and accessing sockets. The holder lays flat in the toolbox drawer, so you can use these in shallow drawers. I use drawer liners, and don't have any problems with picking up the entire holder (i.e. it doesn't get stuck to the drawer). I personally don't stick them to the side of the toolbox, as I don't want to risk any sockets falling out / getting bumped. The magnet is good for holding the sockets in place, but if you drop it, or bang it on something, then be prepared to chase a few. I haven't really had any problems with this though. There is room to mark or label the socket size (using permanent marker), which makes finding the socket you're looking for really painless -- and makes putting them away simple. If you have an apprentice/helper/gopher, this makes life easier for everyone. The deep-well side is deep enough to hold short extensions, or adapters and knuckles (or wobble). However, if you have a fully loaded Holder, picking it up solely by the handle tends to cause a crack over time -- not in the handle, but actually at the end of where the magnet is mounted, where the holder tends to flex. This isn't a dealbreaker, but is a design flaw to be aware of. I prefer the bright orange over the red, purely for contrast/readability of my labels. Regardless, I use these in every toolbox I own. Well worth it.

Worked perfect, fit in my toolbox And sockets are not everywhere

The quality is unbeatable at this price. The magnet is very strong. Won't be losing your sockets using this. All my 1/4 sockets fit perfectly into the slots. Even had some left over for a 3 inch extension and some other drivers.

Great tool for organizing my toolbox keeping all my sockets in place
