NEW Strong Flex door Carabiner

It’s a long process to make the previous design as perfect as it should be, and now the core design feature was mature enough to face on the new usability challenge.

The new design come with only 2 parts, hook and door, very easy to assembly and easy to make different scale for your need.

Scaled capacity of 75% to 120%

Door Flexible Strength = 3 (check out the selflex introduce on http://www.ddf3d.com/)
