Impact Wall-Mounted Boom Arm Reviews

Doesn't do 180 degrees

By Greg
Rated 4 out of 5
Date: 2026-07-31

This thing is pretty great all around, however the listing is incorrect in stating that it can swing left and right 180 degrees, more like 150. To be clear- it cannot get flat against the wall if that's important to you.

Excellent Quality and Huge Improvement

This is extremely useful. Clears out desk stands and tripods. Easy to adjust and install. Love it!

how much weight can this handle if mounted to dry wall?
Asked by: Tyshan
When mounting the Impact 4' Heavy-Duty Wall-Mounted Boom Arm you really need to secure the screws to a stud behind the drywall. If no stud is available in the location you want to mount it I recommend mounting a piece of ply wood or a two by four between two studs and mounting the arm to that piece of wood. It is not recommended to mount an arm to drywall alone.

Does this fold downward to be flat against the wall? (Not side to side)
Asked by: Stephen
It does not, the smaller arm underneath only allows it to go to about 90 degrees perpendicular from the vertical wall mount. It can move pretty far upward but wouldn't be parallel with the mount or completely vertical. I must say it does stay very flat against the wall.
