Full grit surfaces on these stair tread covers and nosings provide slip resistance across the entire surface which increases slip resistance over stripped surfaces.

The multistrip grit on these stair tread covers and nosings has gaps between the gritted surfaces to increase wear resistance and allow dirt and moisture to drain off the surface.

These glow-in-the-dark stair tread covers and nosings have multistrip grit surfaces to prevent slipping. Glow-in-the-dark stair parts are visible in dark areas with limited light. They are often used to mark edges and illuminate exit pathways. They illuminate for several hours before they need to be exposed to ambient light to recharge the glowing effect. Multistrip grit has gaps between the gritted surfaces to increase wear resistance and allow dirt and moisture to drain off the surface.

The double-strip grit on these stair tread covers and nosings have a narrow strip near the nosing and a wider strip toward the riser. The gap between strips increases wear resistance over full-grit coverage.

Raised-disc surfaces on these stair tread covers and nosings allow moisture to move away from the surface to increase slip resistance over flat surfaces. The discs grip shoes and wheels on steps and ramps.
