HORIZONTIAL USE ONLY
Reviewed in the United States on July 3, 2020
Look nice and holds sockets well. Has nice smooth rails so it's easy to position holders for socket spacing.
BUT: If you try to use them in other than a horizontal position, as soon as you take off a socket the holder slides down, to put it back one must slide the holder into position with one hand and use the other hand to replace socket. There are no serrations on the rail to hold the holder in place, just slides down as you go vertical and remove a socket. For other than horizontal use I recommend the Ernst Rails.
