[19.6 lb] Used them on an Avenger A4050CS, which already has the ready holes. Now she glides like butter on a hot biscuit. Girl just needed her dancing shoes!

[Proprietary] Wish they didn't nearly double the cost of the slider stand, but they're rock solid and make it much easier to move our Kessler Shuttle Dolly around.

[Yes] Perfect for the 16.4 Avenger A4050cs Boom Stand.  I cant imagine using the stand without these.  They are large, smooth, very heavy duty, and have an efficient brake.

[Proprietary] I was unsure whether the A9000N wheel set would fit my Avenger A700 boom stand because of its age. I got great advice from B&H in this regard, my order was filled and delivered very quickly, and setup was easy. This has substantially increased the functionality of my boom stand. B&H was the only supplier that had this item in stock and could tell me with confidence that the new wheel set would fit my stand. Thanks for your help.

[19.6 lb] Less than half the price of the Matthew's Slider Stand Wheel Set but built very well and work well with my slider stands. The downside is that they use an allen screw to attach instead of a knob like the more expensive set - this means taking them on and off takes more time. They are also at a steeper angle - I actually like this because the legs won't be as wide, but if you are extending the stands a lot and putting a lot of weight up high, you might want a wider base.

[Yes] The wheels are good if you want to move your slider easy.The quality is good. The black paint on them is not the same like the slider stand paint.The price is a little high for those wheels but if you want to move the dolly easy, the wheels are a must.

[Proprietary] Great product
Great price

[19.6 lb] I use these on my Matthews Digital combo stands. No problems so far and make moving heavy lights easy.

[Proprietary] Works as intended. It's lighter than any other adapter I've come across.

[Proprietary] I picked these up along with the slider stand they go with to make a more compact but robust, travel friendly digi stand for my location shoots. Work great and it's such a plus to be able to remove the wheels and put them back on again. As always a great Matthews product.
