I have the box installed on a HP850 and am very satisfied. It fits into all important for the transport: network and 2 ratchets for load securing, 2 hemp ropes, red flag, trailer lock, bungee cords and gloves. The quality of the box is fine, there is no rust. The lock is robust and I stuck to the moisture Have a tape over the key groove. Installation was simple and has lasted 30 minutes.
