Step 7: Check for plumb and secure

Using a level, hold each 2"x2" spindle plumb (vertical level). Secure the bottom of the 2"x2" spindle to the frame of the deck with one 2 1/2" deck screw. Repeat this step until all spindles are attached. After all spindles are attached, secure a second screw at the top and bottom of each 2"x2" spindle.

At no point along the handrail should there be a space greater than 4" wide.
