Screwgate

The Screwgate is the original, classic, double-action gate mechanism and is still the most secure mechanism in many situations. Despite it not being auto-locking, in the hands of a competent user they can offer many advantages over their auto-lock rivals. Screwgates can be unlocked, have the gate opened, a component clipped and then re-locked with one hand only. This can be crucial in some rope access situations for instance. To do all of this one-handed with an auto-locking connector is challenging to say the least. Even this classic design has undergone continuous evolution and our modern barrels feature a new screw knurled profile to assist gripping in wet or icy conditions as well as increased strengths. We have recently increased the thickness of the gate and thimble to improve the thimble/latch overlap, giving greater security especially across the minor axis (loading across the gate).

All of our screwgates have an in-built limiter to stop the barrel from being over-tightened onto the nose when loaded. This can be especially dangerous when managing a casualty in a two person rescue as it can make escaping the system extremely problematic.

Top Tip: To prevent a screwgate from vibrating unlocked, simply invert it so that any downward movement vibrates it to the locked position.

Kwiklock & Kwiklock ANSI

The Kwiklock automatic locking system is the fastest gate locking mechanism and the simplest to operate. It also provides a convenient solution to eliminating the chance that the gate will accidentally be left unlocked. It has a double action requiring a 90° twist of the barrel to allow the gate to be opened. When the mechanism is released, the gate springs shut and the kwiklock barrel springs back to the locking position – This happens almost instantaneously giving excellent security in a minimum time.

Top Tip: Kwiklock locking mechanism work brilliantly with captive eye or captive bar connectors to form easy-to-use lanyards that require minimum training for use.

All Kwiklocks listed ending with ANSI meet and exceed the requirements of the new ANSI standard – ANSI /ASSE Z359.12-2009 – which became effective November 2009.

All ANSI certified carabiners are then certified to the requirements of CAN/CSA Z259.12-01 (Class 7211-30)

Locksafe & Locksafe ANSI

The classic triple-action, locking mechanism. The Locksafe is almost as simple to use as the Kwiklock, requiring just one extra push-up action of the barrel before the twist, but when locked gives even better protection from accidental opening. This is especially important in situations requiring complex, rope-running systems. A rope under tension may run transversely over other locking mechanisms exposing them to the risk of unlocking. The addition of the third required action dramatically reduces the likelihood of the same rope opening the Locksafe.Top Tip: Keep all Locksafes clean and properly maintained to increase longevity in use.
