The mounting must transfer forces into the building
A tension pole is braced between the floor and ceiling. In many models, a clamping spindle extends the assembly: turning it extends a threaded rod, and the top plate presses against the ceiling. A locknut, if present, is tightened against the corresponding component to prevent the setting from turning back. Other models have their own locking mechanisms. A screw for the operating mode is not automatically a mounting lock.
The compressive force needs a load-bearing surface. A suspended plasterboard ceiling cannot do this, even if there is concrete above it. With timber joist floors, the contact point must be positioned appropriately over a suitable load-bearing component. A detection device can provide indications of joists, metal or cables, but it does not prove load-bearing capacity. Knocking alone is not enough either. Building documents and accessible structural components can help determine the construction. Floor coverings can also yield under pressure, and a floating or sprung floor is not automatically suitable.
Dancing also creates lateral and changing forces. Gradually increasing the load is therefore no substitute for secure mounting. Likewise, slipping due to skin contact is different from a base plate shifting: if the mounting moves, stop using it immediately.
