The bolt used for installing the pRRU on a suspended ceiling plate depends on the plate thickness:
The delivered bolt (M4 x 35) is used if the plate thickness is less than 25 mm.
The delivered bolt (M4 x 60) is used if the plate thickness ranges from 25 mm to 45 mm.
If the screws cannot be tightened using a Phillips screwdriver, use a hex key or an electric
screwdriver to assist the installation.
