I have my GPA drivers in big 10 cu. ft. finished ply cabs, and want to pull them out to transport the cabs.

Last time I had them out was to rotate the drivers about 5 or so years ago, and the gasket on the back of the basket stuck to the cabs pretty hard, and it required quite a bit of force to remove them. A more than slightly uncomfortable amount of force.

Any handy tricks for doing this?
