I installed the UltraFlex in about 30 minutes and it looks amazing on my truck. It’s been on for about two months and not one drop of water has gotten on my BedRug. It arrived with one small clip broken and they apologized and sent two new ones quickly. Great product and great customer service. Don’t hesitate you’ll love it.

Provides bed security and does not obstruct the driver's vision like a fully cap would.

Love the use of existing bolt locations inside the bed. One of the main reasons for purchase. I didn't want a bed cover that just clamped on.
