Reviews: K&M 21231 Telescoping Boom Arm
Paul D. - 06/04/2025
Pros:
The K&M 21231 boom is a good build quality except for the plastic end cap (K&M part number 03-20-938-55) which apparently breaks quite easily. If it was intended to absorb shock, a hard rubber bumper would make more sense. Anyway, I repaired it by gluing a stainless steel 3/8-inch carriage bolt two inches long inside what was left of the plastic end cap. At least it looks better. Time will tell how long this repair will last. I've bought two of these arms that have been already used previously and I am basically satisfied with them. This arm is designed to only fit the K&M 20811 or 21411 stand. If you want to use a third party stand you'll have to get some kind of an adapter.
Cons:
The plastic end cap mentioned above. The K&M 21231 boom arm only fits the K&M 20811 or 21411 stand mentioned above.
Comments:
I am basically satisfied with this product.
Bottom Line:
Yes, I would recommend this to a friend
