I use masterlocks that have the rubberized housing on them, year round leave them out there, only locks ive found that wont seize up in a sense, used other all weather locks, from brinks, with a plastic housing and those just didn't work. Can buy a 3 pack of those rubberized masterlocks all keyed with the same lock which is nice, they come in yellow, blue, black,

I use cable to secure my stands, though I suspect heavy duty chain would be better.

Buy a feeder.....or just a spin unit and attach it to the bottom of a 55gal drum.
