Additional Information

Why It Works Retrofitting Old Railings Stair Balusters Maintenance Overdriving & Torque

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.

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.

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.

Good Baluster Solution

Easy to use. Saved us on labor costs. Helpful for lining up tops and bottoms of balusters. Nice that they can be removed easily to paint around or replace. Only negative, some of the decorative covers don't quite slide all the way down leaving a 1/32"-1/16" gap. It's barely noticeable so we decided not to apply force to try and close it. Perhaps we'll try to later but for now we're very happy with how these worked.

The baluster connectors are the best. They are UV protected vs. the competitors whose connectors continue to crack and fail. And they allow much easier assembly not requiring the top rail removal. Third, it is easy to replace a baluster if damaged.
