Kupo 75mm Caster met rem 22mm ronde adapter set van drie (KS940322)

These wheels are much more reasonable than their Manfrotto counterparts, and the wheel lock system is much easier to lock and unlock with your foot.I purchased these to put on an Avenger A470 Combi-Boom stand. These are not specifically designed for that stand, but I thought I would give it a shot, since the correct Manfrotto wheel set runs somewhere around $170. I drilled holes in the stand legs for the through bolts and attached the wheels. The receiver on the wheel set is designed for larger stand legs, but these snug up well enough when you tighten everything down. The issue I ran into is that these wheels are designed for a flatter stand leg angle than that of the A470. The result is that the wheels are at a wonky angle and they will not track true when rolling the stand. It is still very useable, just not perfect. None of this is a knock on the wheel set, I'm just putting this out there in case anyone is looking at putting these on an A470. Given that caveat, I still prefer using the stand with the wheels, even though they are a bit wonky.The wheel set itself is excellent, and very reasonably priced, and the wheel lock system is far superior to the locks on my other Avenger/Manfrotto wheel sets.

The ONLY issue I have with these is while assembling them, is when tightening the caster stem into its nylock nut inside the leg adapter you will need a VERY thin headed open end wrench, also known as a Tappet wrench. Luckily as a former mechanic I have one. ...I doubt the same could be said for very many other photographers ... But I believe this same issue is present among ALL light stand casters of this style.

smooth and easy install

Although the product description claims they work with any stands that have 1"x1" legs, they don't work with my Matthews combo stand that fits that description. Had to send them back.
