Tumbled Titanium Scales with Tumbled Titanium Core

Titanium -- We've selected Grade 5 Alloy (6Al4V) for the titanium versions because of its incredible strength characteristics. 


STRATO -- Cores


We're excited to offer 2 core variants for the STRATO-biner.  The titanium core will offer a lightweight and sleek design and in contrast, the the tool steel cores will offer greater strength, wear resistance and utility.  The Tool Steel STRATO core also offers extra jimping and a pry bar for more utility and function.

Strategic Jimping

The design is a result of a multitude of ergonomic tweaks. Jimping is strategically placed for the various utilities within the design.

All new gate design for STRATO!

We've designed an integrated, asymmetrical gate that offers great torsional rigidity for a lifetime of use. As with all of the carabiners made by Ti2 Design, the gate is made from grade 5 Alloy (6Al4V) and features an ambidextrous design allowing positive action right or left handed.
