This ceiling rough in bracket is 24 inches in length and fits a 8 inch ceiling speaker. It is typically used to mark the location of the ceiling speaker before dry walling in residential applications.

Please note that speaker rough in brackets are not universal and do not work with all in-ceiling speaker makes and models. This particular speaker rough in bracket is designed to work with our 8 inch speakers listed below and most other 8 inch in-ceiling speakers that require a 257mm cut out diameter.
