Column Sentry® is the original, patented column protector, saving interior building columns by surrounding them with a cushion of air. This protector is very easy to install, without using any tools, and is extremely effective at column damage prevention. It is available in a number of sizes to fit most every column. This column protector is highly visible in its standard safety yellow color, preventing forklift collisions. When hit, Column Sentry flexes, protecting the column, the forklift, and the forklift operator. The protector is molded of low-density polyethylene, making it tough while keeping it maintenance free.
