Rough-in Frames (new construction brackets) are designed for use with in-wall and in-ceiling speakers, compatible with most models. These frames are installed during the pre-wiring phase of new construction, allowing installers to reserve the appropriate space in walls or ceilings and facilitating the precise cutting of hole sizes. Applicable models include RIF200LR, RIF160LR, RIF3160LR, RIF4100LR, and RIF5160L, suitable for speakers such as the Ci200S, Ci160QL, Ci160.2CL, Ci3160RL-THX, Ci3160RLB-THX, Ci4100QL-THX, and Ci5160-THX. This pre-construction frame supports multiple sizes and is ideal for most rectangular Ci speakers, enhancing efficient and accurate installation in new construction projects.
