[Yes] Solid for laptop support while shooting.

[Yes] My AT-213 (alloy) tripod came with a plastic bushing to take up the eighth of an inch space in the center of the tripod. It broke while lowering the tube. I assumed this bushing would come with this new tube, after speaking with Induro,it did not. The used AT-213 (aluminum) tripod I purchased from B+H,fit this tube perfectly. Induro supplied the bushing at N/C,and I returned this tube to B+H. Rather odd both of these tripods did not have the same center diameter.

[Black] The Benro AC2 center column is a 100% perfect fit in the Gitzo Reporter (Series 2, 28mm) column assembly. My Reporter has a Tilt/Roll type head. This is very clumsy for leveling a panning base so I wanted to replace it with my Sirui K40-X ball head. This requires a replacement Rapid-style center column with a 3/8-16 thread. The 57mm AC2 platform diameter is slightly smaller than the 68mm base of the K40-X. This is not a problem as the platform is very sturdy and the ball head is firmly mounted. There is no wobble or instability. The 3/8-16 thread on the AC2 column mates with the ball head without needing an adapter bushing. Install the column by unscrewing the bottom hanging bracket, drop in the column, then reattach the hanging bracket. Other than being a black anodized finish, this AC2 column is a perfect match. I can quickly adjust the ball head platform to level, install my panning base and go. Highly recommended.

[Empty] The listing for this item is a little confusing, but this is the 75mm ball for the Sirui BCT-2203 and similar tripods. It does not come with the adapter ring pictured in the product photo. Great build quality, fit and finish. I really like the weight saving cut-outs (nice touch). Id highly recommend.

[Zipper] These wheels are built like a tank. I feel confident loading up my tripod with a heavier camera setup along with accessories attached. I've purchased and used many cheaper and lighter wheels for tripods, I should've got this one a long time ago. It seems like it's built to last.

[Universal] Exactly what I needed. Actually stronger build than what I had anticipated. Very professional appearance too. Breaks down for transport in seconds. Wheels are quality and lock easily. Overall an excellent addition to my A/V gear.

[Zipper] I'm using it with a Robus RC-5570 Vantage Series 3 Carbon Fiber Tripod, a Nodal Ninja Ultimate M2 panoramic head and Phase One XF camera system. Everything works very well.

[Yes] This small expandable center shaft was the perfect fit for the application. I use it in conjunction with the Platypod base plate and a ball head for remote photography at thoroughbred racing events. The combination of the Platypod base, the Benro shaft and a ball head gives me a multitude of options when covering these events.

[Empty] I own a Benro 2 series tripod that came with a video head. I wanted a bullhead but did not feel like lugging an entire other tripod around. I figured if I purchased this column, I could put the bullhead on it then just change out the center column as my needs require. It has worked very well. I can change the two posts in less than one minute and am pleased with the quality and compatibility of this center column. For short money, it's a great way to get one tripod to work twice as hard. My gear is all about versatility and this matches up with my desire to get as much utility as possible out of every dollar.

[Yes] Good and heavy duty. Smooth and quiet!
