4-Piece Precision Clamp Kit is an essential tool to ensure that the new display or back cover bonds perfectly to the frame. Once the adhesive (such as B-7000 or T-7000) is applied, these clamps maintain constant and even pressure for about 60 minutes, preventing lifting or light leaks from the edges. Equipped with non-slip, scratch-resistant rubber tips, they protect the glass's integrity while ensuring a solid, professional seal.
