Buffering and shock-absorbing material: The highly elastic buffering base material absorbs the vibration from the outdoor unit during operation, reducing wall resonance and significantly lowering the noise level during nighttime use at home. Anti-slip and stable support base: The anti-slip patterns on the bottom firmly adhere to the ground surface, making the equipment less likely to shift during start-up and shutdown, and maintaining a stable state even after long-term placement. Balanced load-bearing structure: Distributes the weight of the outdoor unit evenly across multiple points to prevent deformation at a single point and protect the bottom shell of the outdoor unit from being damaged. Waterproof isolation cushion layer: Prevents water and moisture from contacting the metal base of the unit, thereby slowing down the rusting at the bottom of the outdoor unit. 4pcs Universal Air Conditioning Shock Absorber Cushion For Mounting Bracket,AC Unit Damper Pads,Anti Vibration Pad Reduces Noise
