A vertical suspension assembly 1 is mounted in an elongate reentrant recess (5, Fig 1) of a building component and comprises a first channel element 2 partially nested within a second channel element 3. A biassing component 5 imparts a linear motion between the two channels such that the main body 1 may be adjusted between a first position in which the suspension assembly is inserted into the mouth of the elongate reentrant recess (5, Fig 1) and a second position in which the assembly is anchored within the aforementioned recess. The first and second channel elements may have a substantially V-shaped cross-section with a flattened base 4 between the side walls 3a, 3b. The biassing means may be a substantially circular, elliptical or hemispherical rotary cam, and the cutout portions 9a, 9c are received by the roof (9, Fig 1) of the elongate recess (5, Fig 1).
