Overview
The Maxisafe screwgate oval karabiner is a connecting component for fall protection systems, with a screw lock gate that holds the connection closed until you deliberately unlock it. The oval shape keeps the karabiner stable when connecting harness attachment points, lanyard snap hooks and lifeline terminations.
On a roof or at height, the screwgate is the connection that is not meant to open on its own. The threaded gate gives a positive lock that suits permanent or semi permanent connections, where you want to be sure the karabiner cannot work loose while you move. It is the standard way to join the components of a harness, lanyard and anchorage system.

What You Need to Complete the Job

Frequently Asked Questions
What is a screwgate karabiner used for?
A screwgate karabiner connects two parts of a fall protection system, such as a harness attachment point to a lanyard, or a lifeline to an anchor. The threaded gate locks the connection so it cannot open accidentally while you work, which is why it is used on connections that stay made up for the job.
How does the screw gate work?
The gate has a threaded collar that you turn to lock over the gate nose. To open the karabiner you unscrew the collar, press the gate, and clip in. It takes a deliberate action to unlock, which is the point: the connection stays closed under load and movement.
Is a load rating stated for this karabiner?
The live listing does not state a breaking strength or a load rating for this karabiner, and no figure is added here. If you need a rated karabiner for a certified fall protection system, confirm the gate strength and the applicable AS/NZS standard with the supplier before use.
