Step 4: Newel post holes for rail connection
Required tools: drill, 5/8" dia carbide drill bit, level and pencil.
Install rail spacers at 2 ft. spacing if necessary. Position lower rail between newel posts. Install 2 balusters into pre drilled side holes.
Level bottom rail, install, position and level upper rail.
Scribe rail outlines on newel posts. (at all 4 rail ends) Remove rails and balusters (see figure 4A).
Using rail end cut off pieces, match scribed outlines and transfer holes into newel posts, using 5/8" dia carbide drill bit.
Note: It is always the best practice drill 2 holes diagonal to each other (see figure 4B).

Step 5: Spring loaded pin installation

Inspect pvc pipe ends. Clear ends, if necessary, using a round file. Do not force pin into pipe!
Insert steel pin into open end of spring. Insert this spring loaded pin assembly into 2 of the small holes matching the holes drilled into the newel posts. If bracket becomes jammed, slowly turn pin clockwise and gently push
(see figure 5).
