Column Sentry® FIT
Column Sentry FIT is a revolutionary advance in column protector design. This new, patented product replaces the normal 2 sides with a unique, interlaced 4-sided design. This improves the product in many ways:1. The sliding sides means an exact and perfect fit to each column within each range
2. The 4-sided design means equal protection for every side. 2-sided protectors have 2 flexible and 2 stiff sides
3. The important corner-to-corner protection zone stays constant, no matter what size
