The drywall is fragile and can not support equipment over 150 kg. From 50 kg (washbasin, suspended cabinet, boiler...), it is preferable to integrate horizontal and / or vertical reinforcements in addition to the main frame.
• Up to 5 kg, use X hooks
• Up to 50 kg, install expansion or tipping anchors (fixed in the plate and the frame)
• Above 50 kg, lay down supports and / or structural reinforcements.
