4. Setup & Installation
Proper installation is crucial for the stability and safety of your equipment. This boom arm is designed for mounting on solid walls.
4.1 Mounting the Base Plate
- Drill Holes: Identify the desired mounting location on a solid wall. Use a drill to create four holes that match the spacing of the base plate and the size of the provided expansion screws.
- Insert Expansion Bolts: Remove the nuts and washers from the expansion screws. Insert the expansion bolts into the drilled holes.
- Attach Base Plate: Align the mounting arm wall bracket with the inserted expansion bolts. Replace the washers and nuts, then tighten them securely. The tightening process will cause the metal sleeve of the expansion bolt to expand, firmly securing the bracket to the wall.
