Built for Timber Frame Systems


The Catnic CTF5 lintel is purpose-built for timber-framed buildings with a 50mm cavity. It supports outer brickwork between 100–102mm and includes restraint clips for secure installation.
Its shape and strength offer structural stability across a range of residential timber frame designs, helping simplify installation and load distribution.

Range of Sizes for Flexibility


Available in 150mm increments up to 3000mm, and 300mm steps beyond that, the CTF5 adapts easily to wall openings from 750mm to 4800mm.

Engineered to Last


Constructed from galvanised steel, the lintel resists corrosion even in exposed environments. It holds its structural integrity during and after construction.

Support and Restraint Included


Each lintel includes specially designed restraint clips to help stabilise the structure during building. These prevent lateral movement and twisting.

Performance for Every Project


The CTF5 supports loads of up to 10kN, depending on length and height. It complies with all key structural standards for timber builds.
