T-Lock is a flush—mounted deck base to which a loop can be connected.
A special toggle, which automatically locks-in, fits into the base. It cannot be removed under load, but can easily be removed without a load on it. The toggle can be locked-in permanently which makes it non-removable.

The toggle is swiveling, it can take a load in any direction.
When used as a dog-bone it will adapt to any Dyneema® loop, such as a simple loop, low friction ring with loop and a snatch block with loop.
