Features High Temperature Resistance: The surface of the pressure wheel can withstand high temperatures up to 260℃, and is made of high temperature resistant silicone material, finely processed. Matte frosted surface, wear resistant, smooth, and more resilient. U With A Test Probe: The seam roller can effectively detect the welding joint of TPO coil material, inspect all welding seams to ensure that there is no missing welding, and ensure the reliability of welding seam quality. Convenient Operation: Adopting a 1 wheel 2 bearing design, the seam roller with probe is stable and does not deviate, making the operation more flexible and preventing jamming during the construction process, effectively improving welding speed and const Handle Design: The handle is made of premium wood, which is wear resistant and ergonomically designed. It is not easy to wear out, has a comfortable feel, and is closer to your hand. Wide Application: Mainly used for welding membrane and sheet materials and checking the virtual welding and missed welding of waterproof layer welds, such as PVC, TPO coil welding joints, EPDM adhesive joints, etc. Specification: Item Type: Seam Roller Silicone Roller Wheel Diameter: Approx. 32mm / 1.26in (error ± 2%) Silicone Roller Wheel Width: Approx. 40mm / 1.57in (error ± 2%) Silicone Roller Wheel High Temperature Resistance: 260 ℃ Product Material: Silicone, Beech Wood, High Speed Steel Package List:1 x Seam Roller Package List 1 x Seam Roller
