1. Use of the LockD Clips system
1.1. Intended use
The LockD Clips safety system is used with a connecting lanyard in accordance with EN
362 (Kat Q), a safety harness in accordance with EN 361, or a climbing harness in
accordance with EN 12277, exclusively to protect individuals instructed in their use,
against falls that can cause injury on a ropes course.
It is always used in conjunction with suitable attachment connection: a horizontal or
slightly inclined textile sling or lanyard, or an appropriately rated metal connector. This
textile or metal connector must be chosen by a qualified professional, rated for life
safety and meet all jurisdictional standards.
Danger of severe injury or death can be caused if the
attachment connection does not meet life safety
standards.
Life safety components of a ropes course such as wire rope, attachment rings, or textile
ropes must be equipped with a "Tweezle", a mechanical identification point.
The Tweezle is a type of “key” that enables the carabiners on LockD Clips to lock and
unlock in order to perform their safety function and enable a user to move through the
elements of a ropescourse without being able to disconnect from the life safety line.
Unauthorized use of LockD Clips can lead to severe injury
or death. It is the builder’s/operator’s responsibility
to properly and appropriately provide LockD Clips to
their participants at their own risk.
LockD Clips are intended to be used in the for the following manner:
1.2. In Horizontal Elements with Life Safety Lines
Horizontal elements or elements with only a slight incline in a rope course must use a
Tweezle at the entry point. The user can use the unlocked carabiner of the LockD Clips
to tweezle in order to hook onto the life safety line and allowing the second carabiner
to unlock and detach from the previous life safety line, and continue progressing
through the ropes course.

1.4. In Vertical Ascents/Descents with Fall Arrest Devices
Figure 3: LockD Clips to secure vertical ascents and descents
A fall arrest device requires a Tweezle O or equivalent as an attachment point for the LockD
Clips carabiner. The user tweezles themselves onto the attached Tweezle O with the
unlocked carabiner of the LockD Clips, allowing the other carabiner to be unlocked and
able to detach from their previous life safety line, then ascend or descend using the fall
arrest device.
LockD Clips may only be used on life safety lines that
have been designed by a qualified professional and
inspected according to jurisdictional standards.

3.1.3. Rescue Tweezle
Figure 10: Rescue Tweezle
The Rescue Tweezle is used by trained park staff for assisting users when a user
requires their LockD Clips to be disconnected from the life safety line, for example
when performing rescues, or conducting evacuations. The Rescue Tweezle allows staff
to remove a user of LockD Clips from a life safety line any time needed. The Rescue
Tweezle must only be used by qualified personnel having had appropriate training. If
used incorrectly, the LockD Clips user may have both clips unlocked when at height!
Keep all Tweezles away from unqualified, untrained individuals.

V03.03 | September 2022 | English
ENGLISH 15
A Rescue Tweezle and any Tweezle not permanently mounted
on a life safety line can allow a LockD Clips user to be
unsecured on a ropes course.
3.2. Exchangeable Modules
1
Different modules can be mounted on the carabiner head of the LockD Clips for
different intended uses. The modules can also be different on each head, for example
an abrasion guard can be mounted on one head and a roller can be mounted on the
other head.
3.2.1. Stainless Steel Abrasion Guard
Figure 11: Stainless steel abrasion guard
The stainless-steel abrasion guard (1.5mm thickness) protects the aluminum carabiner
body from wear and damage. The plate can be changed using commonly available tools
following specific instructions, see section 7.5.

5. Before Using LockD Clips
Carry out visual and functional tests before each use.
LockD Clips may not be used if any malfunctioning, deterioration, wear, defect or
vandalism is observed.
Defects must be brought to the attention of the manufacturer immediately to be
examined and repaired by the manufacturer or an authorized representative.
5.1. Visual inspection of LockD Clips
• Check that all parts are present and asses their condition: Carabiner heads, Bowden,
locking housing units, cowtails, etc.
• Check metal parts for possible deformation, cracks, corrosion, wear.
• Check the wear of the abrasion guard.

User Manual
18 ENGLISH
• Check that all screws, nuts and bolts, etc. are in place and tight, gate and gate springs
are functioning properly.
• Textile parts are free from cuts, abrasion, fraying, or any other damage, and sewn
seams and connection & sewn points are intact.
• LockD Clips are securely attached to the harness or safety belt.
5.2. Functional test
• Check to make sure LockD Clips locking mechanism functions properly allowing only
one carabiner gate to open at a time.
• Carabiner gate self-closes when let go after opening.
• Insert unlocked carabiner heat onto a Tweezle to observe it locking. Repeat with other
side to determine proper locking and unlocking of each.
• Make sure both carabiner heads are not unlocked at the same time
5.3. Control of the system
• Check to make sure LockD Clips locking mechanism functions properly allowing only
one carabiner gate to open at a time.
• Determine that LockD Clips are securely attached to the harness or safety belt.
• Place the unlocked carabiner head on a life safety line, then,
• Tweezle to make sure the carabiner locks and the other carabiner head unlocks.
6. Operation of the LockD Clips system
6.1. Initial and Regular Preparations
• Read the instruction manual.
• If possible, obtain firsthand instruction by a manufacturer or a manufacturer’s
representative.
• Ask the manufacturer or manufacturer’s representative to allow you to personally
practice using LockD Clips as an end user would.
• Familiarize users by providing an oral and visual briefing, then allow them to personally
perform the task of tweelzing to lock and unlock the LockD Clips.
• Test before each use that the locking/unlocking mechanism functions properly.
• Do not allow LockD Clips to be used if you find have misgivings, have any questions, or
believe the units are malfunctioning.
6.2. Using LockD Clips as Personal Safety System
The initial tweezling of a LockD Clips carabiner is of critical importance, thus a Tweezle
Barrier with signage should be installed to facilitate and encourage the user to tweezle
prior to entering the first ropes course element. Once the user tweezles onto the
Tweezle Barrier, the user has engaged the LockD Clips system and is secured by its
locking/unlocking functionality throughout the course, until the user is provided an
“exit” Tweezle.

V03.03 | September 2022 | English
ENGLISH 19
Ensure a Tweezle Barrier with signage is installed to
facilitate and encourage the user to tweezle prior to
entering the first ropes course element.
6.3. Open a LockD Clips Carabiner Head
Note that only one carabiner of the LockD Clips system can be opened at a time.
Figure 16: Opening the unlocked hook by pressing on the carabiner gate, the second carabiner remains locked
You can check which carabiner gate can be opened by:
• Pressing the gate of one of the two carabiner heads to determine whether it can press
to be opened, if unable to be opened, then
• Press the gate of the other carabiner head to open and remove from the corresponding
life safety line or specialty Tweezle.
• The unlocked carabiner head can then be tweezled on a corresponding life safety line
or specialty Tweezle.
6.4. Locking the Carabiner Heads by means of a Tweezle
• Place the open carabiner head on the life safety line adjacent to an installed Tweezle
and allow the gate to close,
• Align the locking housing unit at the base of the carabiner head with the center of the
installed Tweezle,
• Push the locking housing unit of the unlocked carabiner head forcefully up into the
center pin of the Tweezle to:
o Activate the internal cable situated within the Bowden shield,
o The locked carabiner head will remain on the current life safety line until
o the connected unlocked carabiner head is tweezled and locked on another life
safety rope.

Figure 18: Lafe Safety Ropes of a Ropes Course with Tweezles Installed
7. Misuse and Troubleshooting
7.1. Excessive Twisting of the LockD Clips Lanyard Arms During Use
If inexperienced users tweezle without thought, lanyard arms can twist several times
until free travel of the Bowden cable is blocked, making subsequent tweezling difficult
or impossible.
Instruct users to straighten the lanyard arms by
regularly un-twisting them after tweezling.
