2.4 Mounting

The LBB 4141/00 and LBB 4141/50 voting units can be snap-mounted and block mounted.

2.4.1 Snap Mounting

The snap-mounting method is used to install flush- mounting units in panels with a thickness of 2 mm. This method uses the ‘click-to-fit’ mechanism to secure the units in cutouts in tabletops or the armrest of seats. See Figure 2.1 for a close up of the click-to-fit mechanism and Figure 2.9 for the dimensions for snap mounting.

2.4.2 Block Mounting

The block-mounting method is used to install flush- mounting units in surroundings of more than 2 mm. This method uses couple pieces (LBB 4127/00) to flush mount the voting units in cutouts in tabletops, metal plates or armrests of seats. The end caps (LBB 4125/00) cover the coupling pieces and complete the attractive design.

See Figure 2.10 for the procedure for block mounting a voting unit and Figure 2.11 for the dimensions for block
