Key item features

  • Noise Reduction: Beyond sealing, the product also helps to reduce noise and vibration associated with window air conditioning units.
  • Simple Installation: Designed for ease of use, the seal is placed on top of the unit, and the window is lowered to compress it, fitting almost any A/C unit.
  • Customizable Fit: The foam material is easy to cut, allowing for a tailored fit to various air conditioning unit dimensions.
  • Product Specifications: The seal measures 1.38 inches by 0.5 inches by 42 inches and has an item weight of 0.050 pounds.

I didn't actually receive this product as it was sold out when shopped. However, I purchased and used it the week before and it was excellent.
