OSL 88 OUTDOOR SPEAKER LIFT GROUND PREPARATION + FRAME INSTALLATION The modular design of this mechanism allows a flexible installation where space can be |STAGE 2| allocated in the ground during the early stages of construction using the Primary Frame. The speaker and flap panels can then be added at a later date. Position the Primary Frame so that the top face of the frame sits 5mm [0.2”] below the underside of the |STAGE 1| finished floor. The floor pit must be excavated to the minimum dimensions shown below.
