A stabilizer-damper for stabilizing a broom, mop, or other long-handled device while such device is resting against a countertop or other surface. The stabilizer-damper is a device that provides stabilization to prevent the long-handled device from falling to the floor and also provides a damping effect to lessen the intensity and harshness of the sound if the long-handled device happens to fall to the floor. The stabilizer-damper fits onto the handle and provides a frictional surface to resist movement of the handle.
