For any home project, be certain to follow local code and permitting requirements.
Posts should be installed at a maximum of 6’ or 8’ on center depending on the railing length being used.
Once you’ve confirmed the desired railing length, you’ll attach the posts using ½” carriage bolts with a minimum joist size of 2” x 8”. The top bolts must be 1” from tops of joists and bottom bolts must be 5-1/8” from top bolts.
Note: Blocking must be added for extra strength.
The attachment of the posts to the substructure is one of the most critical parts of a railing system. Ensure all local building codes are understood and followed. For further recommendations, please contact your local code official.
Slide post sleeve skirts over the post all the way down to rest on the deck’s surface. Then slide the post sleeve over the post and position it inside the post sleeve skirt.
Note: Shims can be used to plumb post sleeves.
Before cutting your railings, position both the bottom and top rails between posts to ensure baluster holes are lined up and spaced evenly.
Make sure to allow for a minimum of 1-9/16” on each end of rail from the edge of the baluster hole to the end of the rail for bracket placement. Mark cut locations on rails at the intersection of rails and posts.
Before attaching the footblock, invert the bottom rail. Next, center and drill a hole using a 3/16” drill bit. This will be the location for the footblock attachment, which will be installed last.
Position brackets on each side of the top rail and on the same side as baluster holes. Then, use the three provided #8-18 x 1” self-drilling screws to attach.
Do the same process on the bottom rail by positioning the brackets on each end of the bottom rail, but this time on the opposite side of the baluster holes. Again, attach using the three provided #8-18 x 1” self-drilling screws.
Using a clean, flat surface, lay the bottom railing on its side. Next, place a scrap piece of 1” decking board to run parallel to the bottom rail for support when installing the balusters.
Insert the balusters into bottom rail slots until they are fully seated.
With the top rail, starting on one end and working toward the other, feed each baluster into its necessary slot.
Place a ratchet strap around the top and bottom rail and tighten until snug. This will help temporarily secure the railing section together.
Note: Do not overtighten strap as you may risk bending or breaking the railing.
Gather scrap material (2 x 4s, decking boards, etc.) and cut at least three support blocks at 3-3/4” in height. Then, place one each on the decking surface beside each post and one near the center of span.
Lift the secured railing section up and center this section in between the spanned posts on pre-positioned support blocks.
To help with railing stabilization, consider using a clamp to hold the first baluster to the post sleeve.
Now it’s time to install both bottom and top brackets on each side to the post using the two provided #8-10 x 2” wood screws.
For best results, set your drill to the lowest speed when installing screws to avoid stripping or damaging your railing.
To attach, secure the post caps with silicone or PVC adhesive. When it comes to attaching the footblocks, refer to the footblock instructions.
Tip: Be sure to clean up any excess adhesive before it dries.
