The MB-C10 consists of five separate pieces and two different types of screws. There are two pairs of steel mounting rails supplied. One pair 14.5" long to span 16" OC members and one pair 22.5" long to span 24” OC members. These fasten to the framing members with screws.
The MB-C10 and the C-10SW are sold separately so that they may be purchased and installed during different phases of construction.
