The Rack Sentry® - End product offers 270 degrees of protection. It is designed to install on the end of the rack installation and can protect both the front and the vulnerable end from collisions. It is designed to visually complement our existing line of Rack Sentry® protection products: 18" (46cm) high, installed with 2 included hook & loop straps. Rack Sentry® Corner guards ideally fits on 3" (75mm) wide uprights, but with this new design it is not impossible to apply this to different width uprights.
