OXAN SCREW-LOCK
Manual locking steel carabiner
- Connector EN 362: 2004 classe B
- NFPA 1983 Technical use
Field of application
This equipment is personal protective equipment (PPE) used for fall
protection.
This carabiner is used to connect equipment together during rescue or work
at height activities.
This product must not be loaded beyond its strength rating, nor be used for
any purpose other than that for which it is designed.
WARNING
Activities involving the use of this equipment are inherently dangerous.
You are responsible for your own actions and decisions.
Before using this equipment, you must:
- Read and understand all instructions for use.
- Get specific training in its proper use.
- Become acquainted with its capabilities and limitations.
- Understand and accept the risks involved.
Failure to heed any of these warnings may result in severe injury or death.
Responsibility
WARNING, specific training in the activities defined in the field of application
is essential before use.
This product must only be used by competent and responsible persons,
or those placed under the direct and visual control of a competent and
responsible person.
Gaining an adequate apprenticeship in appropriate techniques and methods
of protection is your own responsibility.
You personally assume all risks and responsibilities for all damage, injury or
death which may occur during or following incorrect use of our products in
any manner whatsoever. If you are not able, or not in a position to assume
this responsibility or to take this risk, do not use this equipment.
Nomenclature of parts
(1) Frame, (2) Gate, (3) Hinge, (4) Locking sleeve, (5) Keylock, (6) Keylock
slot, (7) Red alert.
Principal materials: steel.
Inspection, points to verify
Before each use
Verify that the frame, hinge and locking sleeve are free of any cracks,
deformation, corrosion, etc. Open the gate and verify that it closes itself
automatically when released. The Keylock slot must not be blocked by any
foreign matter (dirt, pebble, etc.).
During each use
It is important to regularly inspect the condition of the product.
Make sure that all pieces of equipment are properly connected and positioned
with respect to each other.
Consult the details of the inspection procedure to be carried out for each item
of PPE on the Web at www.petzl.com/ppe or on the PETZL PPE CD-ROM.
Compatibility
A connector must be compatible with the equipment to which it is attached
(shape, size, etc.).
An incompatible connection can affect the safety function of the system (for
example, disconnection, breakage, etc.).
WARNING if the connector is attached to an element of the system that is
too large (for example wide slings, large bars, etc.) the connector's strength
can be reduced.

Working principle

Diagram 1. Manipulation
Diagram 2. Installation of the carabiner
This connector must always be used with the gate closed and locked.
When the locking sleeve is open, the red warning indicator is visible.
To lock the connector, screw the locking sleeve until it stops and blocks the
gate from opening.
WARNING, vibrations and/or rubbing can loosen the locking sleeve and
unlock the connector. Check the connector regularly to verify that it is
securely locked.
The strength of the connector is greatly reduced if the gate is open.
The carabiner is strongest when closed and loaded on its major axis. Any
other position reduces its strength.
Diagram 3. Warning danger of death
Any external pressure on the gate (with a descender, for example) is
dangerous. When a sudden tension comes onto the rope, the locking sleeve
can break and the gate can open itself. The device or rope may detach itself
from the connector.
Remember: For your safety, get into the habit of always doubling-up your
systems, especially carabiners.
Supplementary information regarding
standards (EN 365)
If your application requires frequent opening and closing of a manual locking
carabiner (multiple times in the course of a day's work), you should use the
autolocking TRIACT -LOCK version instead.
Rescue plan
You must have a rescue plan and the means to rapidly implement it in case of
difficulties encountered while using this equipment.
Anchors
The anchor point for the system should preferably be located above the
user's position and should meet the requirements of the EN 795 standard
(minimum strength of 10 kN).
Clearance: amount of free space below the user
The clearance below the user must be sufficient to prevent the user from
striking any obstacle in case of a fall. (The length of the connector can
influence the height of a fall).
