(1) Can the Ball-Head be replaced with another, and if so, (2) What is the thread on the ball-head (1/4-20) or (3/8)?

The provided head is pretty nice and can be easily replaceble with any 1/4-20 threaded head.

The Ball Head can be replaced with any 1/4X20 threaded product however, you will lose the compact size if you replace it with one of the larger units. I shoot a D3S with mostly prime lenses and it works OK. If the ground conditions or wind is blowing, I use my larger Manfrotto Tripod with the professional head.

The ball head can be replaced as it has a reversible stud bolt providing both 1/4" x 20 and 3/8" attachments. Just remove (unscrew) the existing head and then remove the remaining disk that locks the bolt in place. The existing Sirui head uses the 3/8" end of the bolt but you can flip it (the bolt) over for a 1/4" head. It can all be done without tools. A replacement head may be advisable as the supplied head locks Arca Swiss type plates by tightening a small diameter knob that may require pliers for removal. This is because the ribber grip will turn and slip when you use your hands. The ball head can be replaced as it has a reversible stud bolt providing both 1/4" x 20 and 3/8" attachments.

Yes, The ball head cann be replaced and the mount screw is 1/4" and 3/8th". I replaced mine to a manfrotto 482 (very small) head to make it even lighter. I have gone back to the original head for more strength. Love this tripod for travel!Herb Booth

Yes it can use an alternate head. Looks like it has a reversible stud with both sizes.

There definitely were threads on my ball valve. I simply purchased a street ell and drained it that way. Someone knowledgeable with plumbing fittings can configure it anyway you want. Bring ball valve to Home Depot and they can help you out.

Dean is confused, Levi is correct. If the top of the ball head is threaded with a standard thread 3/8-16 or 1/4-20 then this clamp could be attached. I would probably recommend some loctite on the threads especially if usign the reducer, of course this is only a good idea if you are not wanting to remove it anytime soon.

Maybe Curtis P got a different product, or was confused because it has a metric ball on it, but the threads on this product are DEFINITELY 5/16-18 thread.No question about it. I tried a half-dozen different 5/16-18 nuts on it and all went on perfectly. Takes a 1/2" wrench to tighten.

I removed and reused the original one. It is only held on with 2 Nuts. And if you need 2 you can Glue it back on.

I have found nothing to replace an Arrowhead. I was told that they use a proprietary coupling thread that no one else makes. I consider myself screwed (excuse the pun).

Yes, you can unscrew the head and mount any standard head to it. I don't remember the bolt/thread size, but it is standard.

I changed it out on mine. I had to take it to a diesel truck repair shop. They removed it and installed the 2"ball to the proper torque. I tried to do it by hand but it is almost impossible. It requires a special impact wrench.

Ask your issue question here. I had wanted support for tightening the head ball but could not find the maker. Luckily I saw the adjustment screw.

I'd bring it to a hardware store and find something that will fit the threads. They're a strange size though, so good luck.

Well, I'm not using this original head and quick shoe (plate), I bought a new video type head when I got this tripod and replaced them. If you are interested buying a new ball head I can sell a original head with quick shoe to you. Please contact me. They are new condition. I can set up a eBay with buy now option.

Yes you can unscrew the head and replace with a different dram head which is what I did.

As long as the ball head uses a standard 3/8 or 1/4 stud this clamp will screw on and work fine.

Hi. I don't think so, as the rotating head is quite wide and there are no spares in different shape that you can use. I hope I was helpfull.

Found another site where it said 1/2"... You can always buy the heads, measure, and then buy the tubing just to make sure. I have an existing system that had a head out. I ordered 3 so I'd have spares. Was easy to replace, about 20-30 minutes to dig around, rotate the head off, rotate new head on, fill in and pack dirt back, then adjust. Use the adjustment tool and follow the directions to adjust the radius arc to get the arc you want. These heads run for years. The only time I replace is when one gets mowed off, like once every two years....

The head is interchangeable with a new head without changing the base. Just make sure when you removed the old one, that you did not crack any of the plastic retention features on the base.

We bought one that was a friction-fit only. Then we found another (on Amazon) that was threaded. You want the threaded version. -Richard &lt;&gt;&lt;
