This Correction Bit is a leverage bit which has a fairly high port, with no cricket (roller) or hood, so the horse''''s tongue naturally goes up into the port as the bit rotates. It''''s designed to stop the horse getting his tongue over the bit where necessary.

If the port is high enough, it can touch the roof of the mouth.

This particular bit has loose, rather than fixed, shanks.

A bit like this has good stopping action, but inexperienced riders should use it with care.
