Used to reduce the vertical daylight of the compression machines and depending on the size of the specimen and considering that, in general, the maximum piston travel is 50 mm.

Ltekonline are the manufacturers of Slotted Distance Pieces used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Concrete Testing Equipment for Engineering Teaching Lab in Universities
