Step 2: Install 4"x4" pre-notched handrail post

Position the notched 4"x4" post, then verify that all posts are spaced equally across the deck.

Using either a post-level or a standard level, verify the 4"x4" post is positioned plumb (vertically level) in both directions. Then using two deck screws, tack the post to the frame to hold it in position. Next, pre-drill two 1/2" holes through the 4"x4" post and frame. Offset the holes slightly as seen in the image to the right. Bolt the 4"x4" post to the frame of the deck using two 1/2" by 4 1/2" galvanized or stainless steel hex bolts, using a washer on both sides.

Note: When securing 4"x4" posts onto corners, the bolts will need to be attached from the edges of the post, due to the positioning of the support board and end board.
