The TWPro MB 2pc Round Fixed Finishing Plate 90° - Ø 125mm is a crucial component for ensuring a tidy and safe installation of your flue system as it passes through non-combustible walls. This plate is meticulously designed for use with solid fuel and gas/oil appliances, including wood stoves, gas coal-effect fires, and oil and gas boilers. Constructed with dual layers of high-quality stainless steel—an outer skin of 304 grade and an inner skin of 316 grade, each 0.4mm thick—this finishing plate promises durability and resilience.
The insulation, compressed rockwool with a density of 200kg/m³ TWPro and 128kg/m³, maximises safety by ensuring proper distancing from combustibles (50mm for TWPro and 60mm for KC models). Fully welded parts enhance the overall strength. This product holds HETAS approval and is CE marked (TWPro EN1856-1 T600 N1 W V2 L50040 G50 / T200 W V2 L50040 O20).
Installation is a breeze with the included Locking Band, ensuring a secure fit and compliance with safety distances.
