The side brick retainer set for the Blacksmith Harness stove keeps the vermiculite fire bricks pressed firmly against the firebox walls during use. Without functioning retainers, bricks can slide or tip inward, interrupting combustion and exposing the stove body to direct heat. This steel retainer set is a low-cost fix that prevents much more expensive damage further down the line. β Compatible with: Blacksmith Harness stove π§ Specifications Material: Heat-resistant steel Quantity: Set of 2 retainer clips Weight: 0.28 kg Part type: Side brick retainer set Side brick retainers are small but important. They hold the insulating lining in place so the firebox maintains consistent thermal performance across every burn. Fitting them takes only a few minutes and requires no tools beyond basic hand tools to access the firebox interior.
