Lift the window buck into place. Ensure the buck is level, adjusting if necessary, prior to fastening it into place. Place kickers to keep the bucks plumb. Once the bucks are in place, continue building until the top of the buck is reached. All bucks must be supported properly before filling walls with concrete. LINTELS REINFORCEMENT Always check local building codes or engineering specifications for correct lintel reinforcement. Horizontal rebar above opening typically will extend beyond the opening 40 times the bar diameter or as specified by local codes or engineering requirements. For example, #4 rebar would extend 20” beyond the opening. 45 diagonal rebar is installed as shown to divert load from lintel to sides of opening. Lintel reinforcement will vary depending on opening size. Charts for lintel widths up to 16’3” are included in the back of the installation manual. These PCA 100-2007, Prescriptive Design of Exterior Concrete charts are also available in Walls for One- and Two-Family Dwellings, a publication available online from the Portland Cement Association () or the National Association of Home Builders ().
