This socket backing locking system has made organizing my tools a breeze! It's easy to use, durable, and has saved me so much time searching for the right socket. My only complaint is that it does take up a bit of space in my tool tray .Overall, I highly recommend this product to any automotive mechanic who wants to optimize their toolkit organization..
Pros
Provides a secure and stable grip on sockets
Cons
May require some effort to secure and release sockets
The Protoco socket tray is a disappointment for the automotive industry .The sockets do not stay in place, and the backing locking system is difficult to engage. The tray is made of flimsy material and not durable enough for everyday use. While the sizing is accurate, the overall design falls short of expectations..
Pros
Accurate sizing.
Cons
Flimsy material, sockets do not stay in place, inconvenient locking system.
I've had these rosette rails for decades; but my last purchase was from Snap-On in 2006. I have about twenty guides total, 1/4", 3/8" and 1/2". They used to be made with "pins" on which the socket slid. The old pin system is fine. New ones Production...like my 2006 Snap-On units - use a molded plastic spring clip and I honestly HATE it.The clips hold the socket in place enough that the spring clip snaps out of the guide.I then have to pre-thread the spring clip digging out the end of the socket
