Simple Installation Workflow
-
LAYOUT & SPACING
Measure your rail. Measure the open span between your stair posts. Mark your spacing layout along the top and bottom stair rails according to local building codes. -
ASSEMBLE CONNECTOR AND ADAPTER
Align the components. Prior to fastening the hardware to the wood, place the square stair adapter firmly onto the bottom of the standard level Snap 'n Lock square base connector, aligning them to establish the correct stair angle. -
MOUNT TO STAIR RAILS
Secure the bases. Position the combined assembly (connector + adapter) over your layout marks on the stair rail. Drive the installation screw tightly through the center of both components to secure them into the rail. -
LOCK THE BALUSTERS
Lock and secure. Once all bases are fixed to your specific stair pitch (33°–38°), slide your 3/4″ square aluminum balusters into place and slide the locking sleeves down until fully seated for a clean, hidden-hardware look.
