They do look good. But remember there are varying sizes of pallet jacks. Got a few different sizes at work myself. Point is, what works for 20mm will work for 25 and 28mm i am sure.

Indeed. We've got the standard Europallets, our own Tupperware pallets (slightly different) and then we have a very small type that carries 2 barrels (2 component silicone) and a large type on which our big bags (containing 1000 kg of raw material) arrive.
