Really nice box, waterproof, solid and secure. I dont have a need for the keyed lock but its nice if you need it. Very sturdy box but i didn't use the U bolts, i used nutcerts and a piece of flat 1/4" aluminum bar for mounting for piece of mind. My dad likes it as a kind of backrest when he rides for hunting since his balance isnt real good anymore at 72. Its on sale as of this review for about $20 less then i paid too.
