Cures mic stand droop

If you've ever had a stand that started to droop in the middle of a show, these are what you need - just a big hunk of metal that counterbalances the boom on a standard microphone stand.

Great quality, perfect fit and finish when using heavy mics with K&M booms. Looks good too.

question
Can I use two K&M 21105 counterweights on the same boom arm? Is there a hole at both ends to allow for this?
yes. I am using 2 on one arm. and there is another trick. if your arms are just a bit thick,you can pop out the plastic liner. I like these, it's hard to find good counterweights these days.

question
What is the thread size? What is the depth of of the female thread?
The only female thread on this item is that of the screw-down mechanism (thumb screw) mentioned in the overview and clearly pictured. Those threads are M6x1.0 and about 17mm deep. They extend to the large central hole at the center of the cylinder but the end of the thumb screw does not bear directly against the boom arm. It instead bears against a plastic liner pressed into that central hole which prevents scratching the finish of the boom arm.
