When building an extension, there is usually the need to knock through into the existing building. This means the builder or the DIYer has to knock a few bricks out to create a hole, which then allows the wall above to be supported using an adjustable "prop" - this is a skilled, difficult and lengthy process, but has to be done properly to prevent the wall collapsing. Whilst this long process is taking place, the existing building is open to the elements and is not secure. NO MORE PROPS reduces this to a minimum, is quick and easy to use and is installed in just 4 simple steps. In fact, NO MORE PROPS has many other advantages over traditional building props.
