Merrill Record PolyWeight - Lightweight Durable Waterproof Hiking Backpack for Outdoor Camping & Travel Adventures

Metal record weights can resonate harmonically with certain frequencies of vibration, amplifying them instead of damping them away. The Merill PolyWeight is instead made of a blend of polymers instead of steel to create a weight with no resonant frequencies. The result is sound quality and vibration control that is improved even further over a conventional record weight. The cork rubber pad beneath the weight holds the weight securely in place without damaging your record labels, and provides superior damping characteristics to felt.
