With the Zodiac, DMMs aim was to produce the best possible offset D locker, specifically designed for rigging. They wanted it to be both tough & exceptionally strong. The I-Beam construction, coupled with a chunky barrel & gate, allowed the Zodiac to achieve this goal, while keeping the weight down to a surprisingly low amount. The final product of all this tinkering is a super robust biner with a keylock nose to reduce snagging, ideal for centre use or anybody setting up heavy duty rigging systems.
