Handrail 4-1/2" - 7

This 4-1/2" - 7 bending rail measures 4.500" wide by .500" thickness. The functional profile is used in the manufacturing of bending handrail around a staircase, most often the thickness of the slat is determined by the radius being bent, the tighter the turn, the thinner the slats. The detail comprises a 1-1/4" wide flat segment on the right, connected to a 5/16" wide by 1/8" tall half-round tongue and groove bead, joined to a 2-15/16" broad line segment on the left side. The pieces are milled separately, as shown, then stacked together and secured; after that process, the lumber is machined again with the shape of the railing milled into the outer pieces of the stacked slats. The outside pieces are often thicker to accommodate the depth of the profile being milled into the side edges of the stacked pieces. This professionally drafted cad dxf file contains two high precision template designs to create cutters for this pattern. We offer a few alternative profiles for your review and consideration, bender rail 2.000" - 16 & bender rail 3.500" - 24.
