The TWPro Structural Locking Band 100 Ø is engineered to provide robust support for up to 2.9 metres of unsupported chimney lengths. Specifically designed for use on solid fuel and gas/oil appliances, including woodstoves, gas coal effect fires, oil, and gas boilers, this locking band ensures stable and secure connections. The outer and inner skins of the product are constructed from high-quality 304 and 316 grade stainless steel respectively, each with a thickness of 0.4mm.
The insulation comprises compressed rockwool with a density of 200kg/m3, enhancing thermal resistance and safety.
