Preciso de ajuda com "drop" neste contexto:

The Flexible Hose is a unique drop assembly comprised of a branch line adapter nipple, stainless steel flexible hose, reducer and a lightweight ceiling bracket.
The Flexible Hose can be installed in false ceilings without cutting pipes associated with installing a drop, armover, and elbows.

Obrigada
