Final answer:
A trapeze hanger is used to support multiple horizontal pipes and includes a channel bracket and straps to hold the pipes.
Step-by-step explanation:
A trapeze hanger is a pipe hanger used to support multiple horizontal pipes. This support system consists of a channel bracket upon which the pipes rest and straps that securely hold the pipes in place. The term pendentive relates to the architectural concept, and while it is also associated with 'hanging' or 'support', it represents a curved triangular form used in the construction of domes rather than a device for supporting pipes.
