If your local building safety codes and regulations or hardware standards rate bolts and nuts by strength, please ensure that your selected bolts and nylon lock nuts are capable of withstanding the weight of the in-ceiling back box and the loudspeaker. Utilizing the two rails and the two carriage bolts with nylon lock nuts, attach the ceiling rail to the "L" bracket on the backside of the back box front plate with a carriage bolt and lock nut, as shown in Figure 4.
