Design Notes
The square profile creates strong, clean lines that complement modern architectural styles. It pairs well with our Matte Black spigots for an all-dark contemporary look, or with Brushed Stainless for a transitional aesthetic. Note that the square profile is not graspable-handrail compliant — if your application requires a graspable handrail, use our round cap rail instead.
