HEMUDU Single Desk Monitor Arm Mount Stand Fit for 13 inch to 32 inch Flat Curved Computer Screen with Swivel, Height Adjustable, Rotation,Holds up to 77lbs, Black

I have this and it works nice. It's a pole style mount and it has a straight through mount in addition to the C clamp bracket. The straight through bolts in through one of the base plate holes. It's static adjustments at 3 specific height levels and is not adjustable (up/down) otherwise. It can hold 77lbs because it doesn't have a slide adjustment which makes for a solid mount Edit: https://a.co/d/00ANP4xi
