  • Metal mesh sleeve for dowel assembly
    Patent number: 4968185
    Abstract: A dowel assembly for use as an anchor in a structural material, such as a light and hollow structural material, includes an axially extending sleeve formed of expanded metal for receiving a hardenable mass and an anchor member. The sleeve is closed at its leading end and is open at its trailing end. The leading end is closed by folds formed in the expanded metal and the trailing end has an outwardly projecting flange. Such a sleeve fabricated from expanded metal is inherently stiff and can be produced economically.
