Ceiling Vibration Damping Mounts, 8 Pack Spring Vibration Isolator Hangers, 110Lb Capacity, 1.2” Deflection Ceiling Spring Vibration Isolator for A/C Air Handler Home Theaters, Studios, Hotels

I'd been looking for something like these dampers for some time. I run propane heat in my workshop and the sound of it running is communicated thru the floor so installation of these dampers not only isolates the heater from the building but also minimizes wear and rear on the heater as well due to reduced vibration.

Used these to make vibration isolators for my racing sim rig.

These mounts are of excellent quality. They are sturdy and should last a lifetime. If you need a floating type ceiling to help dampen thuds upstairs these mounts will help make a big difference.

they are exactly as advertised

Barebones and basic, but functional. They seem fairly sturdy feeling, though the weld line on some of them don't look amazing. Most of them were good, but some of them just look kind of sloppy; I included a picture of one. Overall it's not bad, and it works, but it's not pretty and the quality control seems to be average at best.

These AMGSH vibration damping ceiling mounts work very well. I use mine to hand a small air compressor and get it out of the way. The compressor makes a lot of noise and vibration which can get very annoying and disturb others if I had not used the AMGSH mounts. Now the shelf holding the compressor does not transmit any of the vibration into the ceiling. Wonderful Build quality is excellent; all steel and rubber construction.
