Combisafe Flex bracket 1221 is used where the post bracket needs to be adjusted, up to a maximum of 360 mm, from a vertical surface. Used on walls, vault edges, facades, shaft sides, flat support layer edges and more. The bolt is pre-assembled and the keyhole allows the bracket to be securely hung in place. Then another bolt is put in the lower hole to prevent the bracket from rotating. This is a safe method that reduces the risk of the bracket falling during installation, and disassembly can be done from the vault. Meets the requirements of EN 13374, class A.
