Mark and cut the top rail cover to be the same length as the top rail for all top rail configurations. Next, slide the rail inserts out and cut ¾” from each side of insert before sliding back inside the rail and centering. Cut the top rail to the measurement between the top brackets (same dimensions as bottom rail).

Mark and cut the bottom rail cover 1-1/2” shorter than bottom rail. Slide each rail insert out and cut ¾” from each side of insert before sliding back inside rail and centering. Cut the bottom rail to the measurement between the bottom brackets. Next, cut the bottom rail and bottom rail cover. Take this measurement and transfer it to your rails, ensuring the distance from the last baluster to each post is even.īefore cutting, ensure that the baluster holes on both the bottom and top rail align. Measure the distance from inside of the bracket to inside of bracket. Step 3: Cut Railings for Horizontal Brackets (Post to Post) Then, center the upper bracket on post above the marked line and attach using 3 self-tapping screws. Next, center the lower bracket on post above the marked line and attach using 2 self-tapping screws Then measure up from post base plate 33-7/16" for 36" rail height or 39-7/16" for 42" rail height. If you are not using the template, measure 1-3/8" from top of post base plate or 1-7/8" from decking surface. Center upper bracket on post above marked line and attach using three 2" wood screws. Then, measure up from decking surface 33-15/16" for 36" rail height or 39-15/16" for 42" rail height. Center lower bracket on post above the marked line and attach using two 2" wood screws. Push skirt back onto decking surface before attaching bracket. Slide skirt up to allow for proper measurement.

Measure 1-7/8" up from deck surface to bottom of bracket.
