How does the ball joint lock? If i put something on it will just be loose...and fall

There is a knob to tighten it. However, I personally cannot recommend this device. I bought it to hold a 7 inch monitor and had a hard time getting it adjusted to the angles I needed without it falling. Perhaps they aren't all this way but, mine did not work like I thought it should.

in the middle arm, you got the screw and at the end, you got a screw that you twist. it's very secure as I got this to mount my go pro in my car. it withstood all the road bumps.

The single knob at the bottom right of the picture locks and unlocks all the ball joints - and it works very well.

First and foremost, save your money and look elsewhere for something better made. The ball joint locks in place by tightening the knob. But the one I had could barely hold anything heavy. I would never trust this thing to hold a field monitor, a GoPro is probably ok.

I've got a preview monitor that I use this with a handheld rig. The locking of all points in tighten down by the center handle.First thing is to tighten down the contenting point at either end and then lock down the system with the center handle. For the price I'm stoked with this unit, but if you want to spend some cash buy a bogen magic arm for $130.00 hope this helps. Will

Tightening the dial in the middle joint also tightens the end joints. We use this to mount our son's iPad to his wheelchair tray nad have no problems once we gave up on the jaw clamp and permanently mounted a 1/4-20 socket to his tray. The vise to tighten the jam clamp is pretty weak and in our case, sheared off on both the original and the replacement. Get the arm. Forget the clamp. Buy a Manfrotto clamp instead.

the Ball locks very well but the clamp is the weakest link overall im am happy with it but the clamp would have to be much wider to be effective with the full weight its supposed to hold

It's safety feature .. it tightens against the large nut of the ball to prevent it from rotating

It is on a ball hinge, but is very tight and will only move when you move it yourself and will stay in the position you leave it in.

It locks in place very well. I've had mine up for about 6 months hasn't fallen yet

I don't believe thete is a way to tighten the joint. I have had mine for 4 months and use it every day and don't have a problem with the phone moving positions

There is a long bolt that goes down..loosing it so it drops further and further down. There is an angled round piece with the threaded hole in it and you need to get the long bolt into that hole. Then tighten it up. It needs a lot of tightening.

Mine are loose, too, which creates an unacceptable instability. For such a highly-rated product that otherwise seems pretty solid, this loose connection is really troublesome and unacceptable. They should offer alternative bolts and/or washers to ensure a more snug and professional fit. After all, this is a component that bears weight on each of the different exercises possible.

there is a kind of notch it sits in. It doesn't 'lock' in. But the notch is coated in rubber. I've moved mine all over and its been bumped and hasn't shown any signs of falling out. but if you turn it sideways or upside down it won't hold. Hope that helps.

I had the same problem. It is because it is not very long. I suggest you drill a half inch hole fore or aft of the pin going completely through and install a bolt and nut. That will take out any looseness and be very secure.

Twist (like you would a jar top) and turn it. It will go down and then secure it by turning it into place.

Mine is very tight, no worries about it being knocked loose. If your comes out too easily you may have a defective unit.

I'm not sure why others are having problems, I installed mine two months ago and currently have a broom, a duster and a Swiffer hanging and they have not moved. Put them in the opening, push down slightly and the ball locks it into place.

It's a little tricky, if you twist the top one way it locks. And if you push it down when in the lock position it can get stuck. So keep wiggling it, till it goes down easily, just may take a little getting used it.

I agree with the other answer - it only locks when it's in the upright position.

A light tap with a metal object, like a hammer, tip if a screwdriver, etc should break it loose. You just need the outer housing to break away a little from the teeth that are grabbing your lug nut.
