Front Boards (F) are used to create a standing platform for camera operators and/or assistants, providing a large, safe, carpeted work area that is 5 inches (12.7 cm) above the floor or other surface on which the Dolly is being used. These Boards can be installed on either one or both sides of the Dolly. The gap between the Front Boards for the Low Level Head (LH), Long Low Level Head (LLH) or Quick Change Low Level Head (LHT) can be filled with the Front Board Bridge (FBB) for additional standing area.
