A corner gauge for use in the construction of corners comprises a corner moulding ( 1 ), an extension arm ( 2 ) and a spirit level ( 3 ). The corner moulding ( 1 ) provides a predetermined internal angle a at an apex ( 6 ) and means for attachment to the extension arm ( 2 ) and the spirit level ( 3 ) to provide a corner gauge. Various mouldings providing different angles can be used to construct a corner with a particular angle. The spirit level ( 3 ), may be integrated into the moulding ( 1 ) for convenience and further spirit levels may be attachable thereto for increased accuracy. The extension arm ( 2 ), may also be substituted for a spirit level. A kit can be provides with a series of mouldings ( 1 ) with different predetermined angles, plus a spirit level ( 3 ) and extension arm ( 2 ). |
