The grenade body is of three parts, the two end caps threading into the middle section. Two shallow cones of aluminum, each with a striker and the center of a four-prong stir-rup spring at its apex, are contained in a 1½-in. diameter cylinder held in the middle sec-tion by two collars. One of the cones is at each end of this cylinder and, in the space formed, is a heavy lead ball 1 in. in diameter. The action of the ball in this cavity makes the fuze "allways" acting. The detonators are held in two cylindrical tubes, one attached to the center of each end cap. The end cap is closed by a metal cover, and the explo-sive filling is contained therein. The first safety strip consists of a rubber pull tab and a one-piece U-shaped bar or light, soft metal. Each end of this passes through an opening in the middle section, between a striker and a detonator, to protrude slightly through the opposite side of the body. The second safety strip is attached to the hinged wing-sha-ped safety cap which passes around the body over the middle section. There are two bars, each to pass through the body and cover striker. Thus each striker is held from its detonator by a stirrup spring and two safety bars.

The first safety strip is removed before throwing; and, when the grenade is thrown, the wing-shaped cap will open and pull off, extracting the second safety strip. Then each striker is held from the detonator by the light spring only, and the grenade will fire on im-pact.
