Abstract
A conduit sleeve for a concrete pass through includes a tubular member having an inside diameter for receiving a cylindrical conduit at a forward end thereof. A flange is coupled to a rearward end of the tubular member. The flange is for coupling to a concrete form. A flexing structure is coupled to one or more of the tubular member and the flange for allowing the flange to be angled relative to the tubular member when the flange is installed on a concrete form. The tubular member is configured for receiving a conduit and the flexing structure allows the conduit to remain horizontal when there are variations in the angle of the form. Another conduit sleeve includes a coupling part, a flange, and a plurality of tabs that extend outwardly from the flange.
