VEVOR 51Pack Cable Railing Kit 1/8" Wheel Protector Sleeves, Bundle with Black Invisible 1/8" Swage Tensioner and Terminal, Cable Railing Post Safeguard Covers for 0.41inch Horizontal Hole Post

The product is silver in color.

These wheel protectors are not suitable for 30-degree stair railing posts because they are flat.

You need to first confirm two pieces of information about the "2x2 uprights": ① Whether they are made of stainless steel; ② Whether they have 0.41-inch (10.5mm) horizontal mounting holes. If both are met, the parts can be inserted normally; if either is not met, they will not fit or will require additional modifications (modification carries safety risks).

The product information does not mention any special tools required for installation. However, it is easy to install and use in just four simple steps.

The product description states this railing kit is made of T316 stainless steel and can be used outdoors. It provides strong load-bearing capacity and excellent corrosion resistance for long-lasting use without rusting, even in highly corrosive seaside environments.
