Very strange, this baseplate fits the Manfrotto 501PL / 577 Plate and some other brands of longer, compatible plates (Haoge and SmallRig), but it does NOT fit the Manfrotto 501PLong plate! It is super loose on the 501PLong. However it seems to fit the 501PL/577 and other plates great, pretty tight, with easy top/side loading, which is what I was after. I still need to try it out in the field, but so far seems good. I'm giving it 4 stars because it does not fit the 501PLong. and also because you'll need a 3/8 to 1/4 bushing for one of the screw holes if you attach the bottom to a plate that has two 1/4 holes; this baseplate has two 3/8 threaded holes and a 1/4 threaded hole and it does not come with the bushing (though it should).
I've been looking for a secure manfrotto baseplate that can be dropped in and this was the answer. The smallhd attempt at this has a bit of a wobble and this one is solid once locked.
