bed divider with Bakflip F1

just ordered a bakflip F1 looking for a bed divider to keep a couple things up close to the tailgate. Suggestions?

Thank you in advance

 

I think @BlueBottle uses his oem extender, works well as a divider for smaller stuff

 

Yup. The bed divider doesn’t work but the extender works well for keeping items close by. Just not the cheapest lol. You can always build something out of 2x4’s.

 

I use my tailgate extender for this when my rugged cover 2 is on.
