Air Conditioner Outdoor Unit Anti-Vibration Mount and Noise-Damping Pad Set (4-Pack - 52x40x47 mm)

Made of high-density rubber, this anti-vibration mount set solves at the root the common customer complaint during and after air conditioner installation that "the outdoor unit hums on the wall or balcony". It traps the resonance (mechanical vibration) generated by the outdoor unit's compressor and fan before it is transmitted to the bracket or wall, providing quiet operation.

Key Technical Specifications and Dimensions

• Base Diameter (Width): 52 mm (The wide bearing surface distributes the weight of the outdoor unit evenly and prevents tipping/flexing.)
• Top Diameter: 40 mm (Fits outdoor unit foot recesses perfectly.)
• Total Height: 47 mm (Total profile height including rubber body + stud length.)
• Stud (Bolt) Length: 15 mm (Passes easily through bracket holes, leaving enough length to tighten with a nut.)
• Package Contents: Ready to install; includes 4 rubber mounts with washers and fixing nuts fitted.

Technician Tips and Installation Advantages in the Field

• Especially in installations on masonry brick, thin walls or inside enclosed balconies, serious humming (resonance) occurs if the outdoor unit is in direct contact with the sheet metal bracket. These anti-vibration mounts eliminate metal-to-metal contact and create a flexible insulating barrier in between.
• When you replace the hardened, worn-out foot rubbers of old air conditioners with this set, there is a visible (and audible) drop in the unit's noise level; it minimizes callbacks.
• Because the studs are pressed (vulcanized) into the rubber body, they do not strip or spin over time, and they show high resistance to harsh outdoor conditions (sun, rain, frost).
