INSTALLING A COMMON 36" TALL STAIR RAIL


Here is one way to build your stair rail using Snap'n Lock Stair Adaptors and Shadow Rail Connectors.


The elevation contact points for the 2x4 rail connectors depict one possible configuration resulting in the top rail meeting the newel post at 36" above the deck surface.


The gap between the underside of the lower rail and the surface of the treads may permit a 6" ball to fit underneath but never greater. The bottom rail may be set lower to the nosing of the tread if desired.


The angle of typical code-compliant stairs ranges between 34°-35°. Baluster lengths shown here assume the Snap'n Lock connector and stair adapters are used. Baluster lengths may vary if the angle changes but rarely exceed 25".


Installing A Common 36" Tall Stair Rail

Do not let the simple look of the Snap 'n Lock™ Balusters fool you.  A lot of thought went into conceiving this design in order to make it work so well.  The base and the collar are designed to incredibly tight tolerances so they fit together like a glove and constrict around the baluster to hold it tight eliminating any wobble.


The sidewalls of the base are free to flex and accept the baluster as it is pushed in place.  The mating surfaces of the base and the collar are sloped so that as they slide together the fit gets tighter and tighter until they lock together once fully seated.


The parts can be released by fitting a slot screwdriver under the color and popping it up.  This allows for easy maintenance or the addition of decorative baluster collars anytime after installation.

PERFECT FOR RETROFITTING OLD WOOD RAILINGS

STEP 4

With traditional plug systems, you have to take down the entire railing and rebuild from scratch.


Make sure to measure the gap between your upper and lower 2x4 rails and pick the 25" or 31" and then cut them down to your specific gap less 1/2" for the thickness of the base connectors.


Aluminum is so easy to cut and is not subject to oxidization the same way ferrous metals are.


This saves you a lot of time and money. But the best thing is that you just gave your old worn out wood railing a brand new life.

BUILDING STAIR RAILS WITH SNAP LOCK BALUSTER STAIR ADAPTERS

Let's take a closer look at how the stair adapters work with the Snap Lock Balusters connectors. No need to cut balusters at an angle. 


Just snap the adapter to the underside of the base connector and screw the unified parts to the 2x4 as normal.


The shorter 25" balusters are recommended for most common stair rail applications.

Just slide and lock the collar down when you are done.

PLEASE FOLLOW THESE PRECAUTIONS WHEN FASTENING BALUSTER SADDLES


  • Do not use impact driver. Neither the screws or the connectors are designed for installation with an impact driver.

  • Use a variable speed screw driver and set torque to low-medium.


Overdriving screws into the connectors can damage the connector and reduce lifespan.
