    Are there other choices?

    Don’t get the screw lock or maillot. This is so much safer and easier

    The ONLY Omnidirectional "Mallion" you should own!

    First let me say this is totally worth the $5 extra dollars than the Petzl SL Omni Lock biner, but the fact that it is an auto-locker means you no longer have to worry about the rope/your gear unscrewing the lock on ascent! I love my Omni but this is light-years ahead, and it weighs to much less than a steel maillon. Yes, it's expensive, but it probably the single most important piece in your SRT rig. You're welcome!

    good product

    Nice option for the screw/unscrew of the maillons. The downside is the 20 kN max, I'll feel more secure with at least 25 kN.
