Plastic tabs on leg locks broke

Find parts here: http://www.manfrottotripodparts.com/monopod559B-2.html

They were not made to be serviced. They were made to be disposable essentially, but you might contact the folks at B&H to see if they may have a solution.

Otherwise depending how it broke, it might be able to be cemented, or reconfigured to accept a different type of clamp. I had a no name type of tripod that required some caredul filing to restore a lip on a clamp so it would lock after the original lip snapped off.

Try www.bogentripodparts.com for new locks. There is also a video on how to replace locks( not your particular model, but will work)

I carefully used a needle nose lock pliers on the plastic part with channel locks on tripod leg and was able to loosen the part. 

the plastic locks on our vivitor 980 tripod legs are broken now can i replace them. jan

Assuming you still have the female part with the treads in tact, you can do what I did. I used a hose clamp, the kind used on radiators, but larger. First, take off the lock down knob, then put the hose clamp over the broken plastic housing and mark where the knob would screw through. Then remove the hose clamp, placing it on a sturdy surface and use a 5/16 drill bit to make a hole where the lock down know will pass through. Place the hose clamp over the plastic housing, insert the knob, tighten the hose clamp (but not so much that it restricts the tripod leg from moving) and you are done! I can send you pictures of the process and the final result. It saved me from buying a new tripod! I can be e-mailed at [email protected] if you have questions.

I would contact the factory and see if they have replacement part available. Try their website and ask. Most large retail manufactures have parts avaiable.

On the velbon vgb 3, the leg locks consist of a lever, one or two pieces of metal and a plastic piece. The metal and plastic pieces rest in a depression against the lever. When the lever is pulled out, pressure against the smaller leg section is released. When the lever is pushed in, pressure against the smaller leg section is exerted, locking the legs in place. On the back side of each joint, there is a phillips head screw which acts as a stop to keep the leg section from coming all the way out. When the screw is backed out, the leg section can be removed, exposing the latching mechanism. If the only problem is that the latch mechanism came apart, it can simply be reassembled. If, however, something broke and allowed the latch assemby to come apart, that will have to be dealt with as well. My guess is that the phillips screw may have become loose, and the latch came apart.
