Column Sentry® is a highly visible, easily installed way to protect your interior building columns from forklift collisions. Column Sentry absorbs vehicle impact through the combination of product shape, materials, and Sentry's patented air-cushion system. Column Sentry is available in 14 sizes to fit closely to your particular column size. The product is constructed in two halves and is installed easily around the column, connected by wrapping the product with the included professional hook and loop straps.
