A wall plug is a type of fixing used in building. It allows screws to be fitted into masonry walls.
The original wall plug, the Rawlplug, was invented by J J Rawlings in 1919, and the name has become generalized in the UK, applied to wall plugs from competing manufacturers.
Early wall plugs were thick-walled fiber tubes, but most current brands are plastic.
Wall Plugs are ideal for external and internal wood joists and beams. No pre-drilling is required for most hard woods. It can be used as an alternative to coach screws and bolts.
