The MAGRAIL TL, from Durston/VIM Tools, has moveable round pegs that can be tightened anywhere along the magnetic base. A powerful magnetic force holds the socket in place, and the rail tight to the toolbox sides, lids and drawers (even through most drawer liners). The socket pegs are available in 1/4", 3/8", and 1/2" sizes. The "Tilt and Lift" TL offers the easiest way to remove the sockets:tilt them to one side and lift.
