Long Lasting

I've put it through the wringer

This locker has easily lasted me three times longer than any standard aluminum locker. Well worth it.

Great biner for belaying

I've put it through the wringer

The HMS Bulletproof is great for keeping your biner from rotating while using it with an ATC for belaying. Clip the retainer to your belay loop to keep it from cross loading. There is a steel insert which extends the life of your biner. This is the biner that comes with the Mega Jul Belay Kit and it also comes in a Triple lock version.
