Chimney Rafter / Joist Support Bracket 800 mm
Description and Purpose
The Rafter / Joist Support Bracket (clamp with console arms) is an element for the spatial fixation of the chimney. It is used in places where the pipe passes through inter-floor ceilings, attics, and the roof system.
Main Task: To rigidly fix the chimney in the center of the opening between beams or rafters. This prevents the pipe from swaying in the wind and guarantees that the hot chimney will not shift and touch wooden structures, maintaining safe fire clearances.
Key Features
- Universal mounting: The set consists of a clamp and profile pipes (mounting arms). You can secure the chimney between two beams (using 2 supports) or anchor it to a single rafter leg (using 1 support).
- On-site adjustment: The standard length of the arms is 800 mm. During installation, excess profile length can be cut off, adjusting the bracket to the pitch of your rafters.
- Robust construction: The product is made of welded profile pipes (EN-1090-2 certificate) and powder-coated to protect against corrosion.
Technical Specifications
The bracket is selected based on the outer diameter of the chimney.

Safety Warning
- Not a load-bearing support: This bracket works only for lateral (horizontal) stability (preventing the pipe from wobbling). It is NOT designed to support the vertical weight of the chimney. The chimney stack must rest on a base platform or load-bearing wall brackets.
- Fire clearances: Use this bracket to strictly fix the pipe at a safe distance from combustible ceiling materials (according to the norms for your type of chimney).
