Precautionary expansion of the Recall Recall of all delta karabiners FD00A

In the course of routine tests anomalies in strength of the major axis was
observed at several pieces. Caused by inhomogeneous raw material, minimal stress
cracks can occur at the bending. These cracks can be tricky, because they do not
occur immediately. Due to following tests and analysis, and in consequence of
this, to avoid any risk to our customers, AustriAlpin has decided to take a
precautionary extension of the current recall "DELTA carabiner"

Immediately stop using it!
