Question 17

When do I use knockdown or split frames?

Accepted Answer

Knockdown and split frames are designed to suit stud walls. They are installed after the stud wall has been cladded/gyprock installed. Some experienced builders/customers use split frames on existing brick by first securing timber down either side of the brickwork (using a dynabolt or similar) and then screwing our split frame into the timber. As this is not the intended use of the frame, this will be at the customers own risk. We also offer dynabolt prep alternatives to our fully welded frames. Please speak to our team if you are planning to use our frames into existing brick in order to discuss best options.
