Abstract
A mine stopping panel is disclosed. The panel includes first and second channel-shaped panel members having a telescoping sliding fit one inside the other. An elongate end cap is fitted in the first panel member. One or more louver connections between the first panel member and the end cap hold the end cap against movement relative to the first panel member when an extending force is applied to the end cap tending to telescopically extend the first panel member relative to the second panel member.
