In principle, our hanging systems can be attached to all conventional wall types (i.e. concrete, brick, hollow brick, sand-lime brick, plaster, plasterboard walls, wood, etc.). Of course, the load also depends on the total strength and construction of the wall itself. When mounting the hanging system on walls with a less solid construction, it is advisable not to fully utilise the maximum load of the system.We supply universal plugs with the majority of our sets, which are suitable for most solid and hollow walls. Some very uncommon walls may require different, more specific plugs.When in doubt, ask for advice from a builder, a skilled DIYer, or your local hardware store.
