【Efficient Exhaust Sound Insulation Roller】: The seam roller is specially designed to reduce air bubbles during the construction process of insulation materials. The sound deadening roller significantly improves the sound insulation and heat insulation performance by maximizing the bonding effect of the sound insulation pad, creating a quieter and more comfortable interior environment. 【Bidirectional Bearing Design】: The two-way ball bearing structure ensures smooth operation without jamming and smooth rolling when the silicone sound deadening roller is used, ensuring that the laying process of sound insulation and heat insulation materials is efficient and labor-saving, improving construction efficiency and comfort. 【Dual Size Roller Set】: The set includes two noise pressure rollers with different wheel widths, large and small. The large size is: 5×3.5 cm, and the small size is: 3×3.5 cm. Two different wheel widths allow the soundproof roller to handle both large areas and narrow corners with precision, so it is an ideal choice for various installation scenarios. 【Premium Silicone Roller】: The automotive sound deadening roller is made of wear-resistant and high-temperature-resistant silicone, with a wooden handle and stainless steel bracket to ensure durability and no damage to the sound insulation material. The ergonomic long handle can reduce hand fatigue during long-term use, providing a comfortable grip and excellent control experience. 【Multifunctional Soundproof Roller】: The silicone seam roller is suitable for flattening and bonding of different materials, including car soundproofing and heat insulation pads, flat film, wallpaper and leather products. The sound insulation roller can be used in a variety of sound insulation projects such as car audio, home theaters and recording studios. It is a multi-functional solution for various DIY projects and professional installations to achieve bubble-free construction effects., Manufacturer: EZVEZS
