Summary:unique reverse notch & hole gate, plastic threads
Description & Commentary:

As of June 2023, I have not found the name Austrialpin uses for this unique gate latch arrangement. I consider this strange design a reverse notch & window/hole gate (see the Stubai (twisted d) for a normal notch & window), although the notch (on the gate) is a integral post on the gate. The window is a round hold formed on the flattened nose.

The threads & sleeve stops are a single plastic insert placed in a slot in the front of the gate, a design I assume to minimize material use and ease machining time. The locking sleeve is made from brass.

Otherwise, this is a typical HMS round-stock steel carabiner.
