JanSass, I bought one of those tools from CW...you replace the metal handle with a knob that has a D-ring and the long handle that comes with the kit has a hook that fits in the D-ring so you can crank the vent open. Be careful if you install one of these. The screw in mine kept vibrating loose and I would find the vent partially open when I stopped...luckily the wind didn't rip the cover off.
