[3 lb / 1.36 kg] Bought two sets for my Manfrotto boom stands. Casters are heavy, but solid. Manfrotto stands have a pre-drilled hole for the caster plastic tabs which have a slightly raised bump that fits in the hole to prevent the casters from twisting on the 22 mm tubing. The casters are attached with M6-1.00 metric screws with a flat-head. I replaced these with some hex screws for quicker installation & removal on location. Thumb screws would probably protrude too far and interfere with caster rotation. The 100mm (3.93) caster wheels make moving stands much easier, although they add significant height to your stands. The locking feature is nice too. Overall, great product.

[3 lb / 1.36 kg] So awesome, so smooth for movement, looks and unlocks as they should. Anyone who says they are tough, well they work as all should work. PERFECT!

[3 lb / 1.36 kg] What I should have purchased along with the cine stand. I'm glad I went with the larger of the two sets, it makes rolling from different surfaces with a boom, light, and box effortless. Perfect.

[3 lb / 1.36 kg] Impact Locking 3-Caster Set for 22mm is perfect . smooth , sturdy and well built. make this your chose ...

[3 lb / 1.36 kg] I've purchased wheels for all my heavy duty light stands. I find it to be the safest way move top heavy studio equipment. The wheels allow for fine adjustments to the location of lights without having to lift the base of the stand off the ground. The end result is the stands are less prone to toppling over. When choosing caster sets I always try to purchase the largest wheel diameter available. The larger the wheel diameter, the easier it is to roll over cables and imperfections in the floor. I also strongly recommend locking wheels to be sure the equipment stays exactly as you left it. In short, the investment in castors can help prevent accidents which can otherwise be quite costly when it comes to replacing expensive flashes and/or continuous lighting.

[3 lb / 1.36 kg] This is a sturdy and secure server rack for those unique situations. I'm happy with the purchase. And it came assembled. Even better.

[3 lb / 1.36 kg] I found these to be extremely well made. They are perfect for folding tripod light stands. As you might imagine, it's so much easier to roll a stand than to carry it around, especially with the added weight of a light and modifiers.

Yes, the tripod legs have to be at the proper angle in order to have the best rolling experience. It's really not an issue. When I first installed the wheels and set the proper angle, I marked the center column just above the upper leg casting. Now, when I open the stand, I can easily set the leg angle to the perfect position. Done!

The brakes work very well, and the three-inch polymer wheels roll nicely over any flat surface, even carpeting.

Just make sure your sizing them correctly to your stand legs. These are the 25mm version, but Impact also has a set for 22mm legs. You'll save even more on those.

So, get rolling... You won't regret it.

[3 lb / 1.36 kg] These are nice! I lucked into being gifted a Manfrotto superboom but it had no casters. I read the reviews here on B&H and went with these big boys. I'll tell you - Manfrotto thinks of everything. There is only one way they go onto the legs so their position is perfect. Operation is absolutely smooth.

[3 lb / 1.36 kg] Great build on these casters. I wish I didn't wait so long. moving anything that's boomed is made effortless and much safer.

[3 lb / 1.36 kg] These casters will speak for themselves. They install relatively easy and are extremely sturdy!
