Klein Tools 931-9RE Rare Earth Magnetic Torpedo Level

The 931-9RE has a V-grooved edge machined into the frame specifically for pipe and conduit work, so it seats on a round surface instead of rocking on it. The rare earth magnets hold it there hands-free on iron and steel, which covers EMT, rigid conduit, and black pipe. On copper, PVC, or aluminum conduit the magnets do nothing, so you are holding it by hand and relying on the V-groove alone.

Klein rates the rare earth magnets on the 931-9RE at up to 5X stronger than the strip magnets used on conventional magnetic torpedo levels. Practically, that is the difference between a level that stays put on a vertical strut or overhead steel while you work both hands, and one that creeps or drops. It grabs iron and steel only.

Yes, and that is what the top-read window is for. The 931-9RE puts a viewing window on the top face so you can read the vial looking down at it, rather than having to get your eye square with the side of the level. In a loaded panel, a tight joist bay, or against a wall where there is no room beside the tool, that top read is the only view you get. The vials cover plumb, level, and 45 degree.

Three vials: plumb, level, and 45 degree. The 45 vial is the one that matters for setting conduit offsets and kicks, since a standard offset bend is cut at 45 degrees. All three are large-format vials for visibility.

Extruded aluminum frame, not molded plastic. Extruded aluminum is what keeps a torpedo level's reference edge straight after it has lived in a tool pouch or gotten dropped off a ladder, which is the usual way a cheap level goes out of true without the user noticing.

Klein Tools 931-9RE is the manufacturer part number for the rare earth magnetic torpedo level. There is one configuration, so there is no finish, length, or magnet option to specify when you order it.

There is a hang hole built into the aluminum frame of the 931-9RE, so it clips to a belt hook, hangs on a pegboard, or drops onto a carabiner. Useful on a truck-stocked van or a shop where the level needs a home rather than a drawer.
