Every door and panel on the SmartCap® Edge Defender is built out of stainless steel to hide and protect your cargo from would-be thieves. Plus the Edge-to-Edge door design offers one of the largest side openings of any cap every made—making it crazy easy to get large stuff in and out of the bed. And we haven't even gotten to the new Gullwing-Bin system that lets you transform your truck bed into a mobile workbench meets tackle box meets organized life. Your mama will be so proud!
