I found mine on Amazon, choose the ones I did because they have the ability to be calibrated. I check them with boiling water and they're super easy to maintain.
As far as the latches either harbor freight or again Amazon.
Got the RF plate in and the tracks for food racks. I have a neighbor with a brake that can do 1/4" up to 10ft. We put a 174 degree bend length wise on the plate. We could not do a cross break for center drain because the tank was about 3/8" out of round from one end to the other so I cut the plate obtuse and split it in half to fit. Worked out level from one end to the other and had a heavy 1/8"per foot slope in all 4 directions for a center drain. Still have to plumb it but it was a good fit. I used a 1977 oxy acetylene track torch I picked up for $75 at an auction. Smith 0/ cutting tip. Not a plasma cutter but if you get your heat and speed right it does a nice job with no warping. It cuts up to 3" thick and they don't mak'em like that any more. maybe it's starting to look like a smoker?
