Plugs for rectangular pipes

Example of marking a rectangular pipe 60x40x2.5. the first number 60 is the outside dimension of the pipe (larger face) in mm, the second number 40 is the outside pipe dimension (smaller face) in mm, the third number 2.5 is the pipe's wall thickness in mm.
If you require a plug inside or outside on this pipe then the name (size) of the plug corresponds to the outside dimension of the pipe.
So you need to choose a size of 60x40 mm in the section of internal or external rectangular plugs.
