16 Pc Original Tray Stackers for Harvest Right Freeze Dryer Trays – Stacks 5 Trays – Green - Freeze Dryer Machine Accessories – Freeze Dried Food Storage - Made in USA

I bought these stackers and absolutely was frustrated with them, didn't like them, and was wanting to return them. But, I decided to look at the amazon listing again to make sure I wasn't being stupid (which I was.......). I was using them upside down, trying to clip the skinny end on the top of the tray, and using the wide end to support the tray above, which was 100% wrong. By not paying attention to the pics on the listing and using them incorrectly, it allowed the trays to touch the food below, they were unstable, and would pop off, leading me to be more frustrated (they fly pretty well when you chuck them across the room while cursing them). After checking the listing and seeing the pic that showed proper orientation, I flipped them around and they work wonderfully! This is a well made product that does exactly what it says it does, and let's you stack the trays while not letting food touch the tray above it. I would recommend this product to anyone with a Harvest Right freezer.

I always wait until I have used something for awhile before writing a review. We have been using these on our Stay-Fresh FD trays. The Stay-Fresh FD trays for both the 4 shelf and 7 shelf FD versions are 8” x 20” x 0.75 in high. The Sophos Survival brand tray stackers fit perfectly on our Stay-Fresh trays. They go on and they stay on. And since we have a 4-tray FD, one 16 piece set works for every four-tray set we have. We use the stackers so we can “grab” and move 4 trays at a time, and then we pop them in the freezer that way so it takes up way less shelf space. Of course, the stackers come off the trays as we place them into the freeze dryer. AND, I love the idea that these are made in the U.S.A. ENJOY!

For these for our new small FD and they work pretty well. They are easy to get on, but aren't a snug fit so also fall off easily. They seem like they will last forever and I 3D printed a sleeve to hold them all on the table rather than in a pile.

These work really well for stacking my harvest right trays... So much easier to carry around. I do most of my prep work in the kitchen and my freeze dryer is in the garage, and these allow me to carry all five trays and one trip. I have the medium size machine, and these fit and work well. They're very secure and well made.

Will not work on other trays
