Our Mission

KLON, LLC is on a mission to make weightlifting safer and the DB300 is the beginning. When used properly, the unique design of the DB300 will eliminate the awkward movements that lead to the most common injuries during these routines.

The DB300

This ingenious device provides a flexible way for lifters to safely get the most out of their dumbbell press routines in a timely manner. The DB300 complements most Power Rack style cages, equipped with one inch (25mm) posts.
