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.

This helpful visual guide is worth a thousand words and shows just how simple it is.

The shorter 25" balusters are recommended for most common stair rail applications as shown in the diagram.

Handles a Range of Rise and Run Angles

HANDLES A RANGE OF RISE AND RUN ANGLES

The adapters are set at 35 degrees to match the common rise and run for stairs under the residential code. 

But sometimes you might have a slightly shorter rise and a longer run.  This changes the angle slightly and can differ from the 35-degree default.

Don't worry. They have enough flex to accommodate stairs from 33 to 38 degrees.

The baluster connectors are the

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.
