I installed the Apache 2800 on my Rad Rover Step Thru rear rack. There are screw holes on the rack and I measured the bottom and drilled the holes. I used 4 M5X15mm star knobs and washers to screw it into the holes. Also, I attached kayak eyelets to the front and back for bungee cords for extra cargo. Lastly, I bought two keyed alike master locks, so I can lock the case.
Looks great and well done.!!
It's hard to find a REAL waterproof rear rack bag??? Good job!
