Hey Denny! So long as you do not overload the Thule Force 3 L Sport Rooftop Cargo Box item # TH77SA it's pretty easy to open and close. It has dual-sided access, which means you can open it on both sides of your vehicle for added convenience. The latch can be opened using only a finger and thumb. You're going to want to be careful opening it in the wind though.
What kind of vehicle are you looking to mount this cargo box on?
