Anchorage requirements (Fig. IV)
• According to EN795 the minimum strength of any anchorage is 10kN
• Check anchorage for signs of deterioration
• Like all fall arrest gear, anchorages must be subjected to regular inspections through a
competent person. Inspect at least once every three months, and record findings in a dedicated
service record
• Check that the scaffold hook is the correct size for the anchorage to be used. If the scaffold hook
is too small, use an anchor sling to connect to the anchorage
Anchorage position
• The anchorage of the system should preferably be located above the user's position
Use as part of a fall arrest system
• Anchorages selected for fall arrest systems should be capable of sustaining a static load, applied
in the directions permitted by the system of at least:
• 22kN for non-certified anchorages, or
• 2 x the maximum arrest force for certified anchorages
• If more than one system is attached to one anchorage, the required strength shall be
multiplied by the number of systems attached
Use as part of a work positioning system
• Structures to which a work positioning system is attached should be capable of sustaining
a static load, applied in the directions permitted by the system of at least 13kN, or twice the
potential impact force, whichever is greatest. If more than one system is attached to one
anchorage, the required strength should be multiplied by the number of systems attached
Use as part of a restraint system
• Anchorages to which a restraint or travel restraint system is attached shall be capable of
sustaining a static load, applied in the directions permitted by the system of at least
• 4.5kN for non-certified anchorages, or
• 2 x the foreseeable force for certified anchorages
• If more than one system is attached to one anchorage, the required strength should be
multiplied by the number of systems attached
Compatibility
• This scaffold hook is compatible with miscellaneous fall arrest systems and safety gear, including
but not limited to the following Silverline products:
• Restraint Harness
• Fall Arrest Harness
• Fall Arrest & Restraint Harness
• Shock Absorbing Lanyard
• Restraint Positioning Lanyard
• Wide Back Support Belt
Notes:
• Connecting hardware must be compatible in size, shape, and strength. Non-compatible
connectors may accidentally disengage and lead to serious injury or even death
• Only use connectors, such as D-rings, snaphooks, karabiners and other equipment with a
minimum rating of 22kN
• ALWAYS take the length of the scaffold hook (see 'Specification') into consideration, when
planning the layout of a fall arrest system, as it will influence the total length of the fall
WARNING: Always verify that the connecting karabiner and the D-ring on the harness or
anchorage connector are compatible.
Operation
Note: This equipment must ONLY be used by competent operators. All users must be trained in
its safe use. Inexperienced users must receive instruction prior to using this equipment. A risk
assessment must be carried out before undertaking any operations requiring fall arrest equipment.
WARNING: ALWAYS wear personal protective equipment appropriate for the work area and
type of activity, including but not limited to eye protection, gloves, hard hat, protective shoes and
hearing protection.

Opening and closing (Fig. V)
WARNING: This scaffold hook must ALWAYS be used with the Gate (4) closed and fully locked! To
check whether the Gate is securely locked, try pushing the Gate open from the outside; it must not
open without the Locking Lever (5) being operated first.
1. Push the Locking Lever (see Fig. V: "1") towards the hook's Spine (3)
2. The Gate (see Fig. V: "2") is now unlocked and can be pushed in to open
3. Release the Gate and the Locking Lever to close
Making connections (see Fig. IV & VI)
WARNING: Never apply multiple loads to a single scaffold hook.
• When using a scaffold hook to connect to an anchorage, ensure that accidental disengagement
('rollout') cannot occur
Note: Accidental disengagement is possible when interference between a karabiner or scaffold
hook and the mating connector causes the karabiner's or scaffold hook's gate or keeper to
accidentally open and release.
• DO NOT use connectors that will not completely close over the anchor point
• DO NOT make knots in a lanyard
• DO NOT hook a lanyard back on to itself
• DO NOT attach two or more karabiners or scaffold hooks to each other
• DO NOT attach two or more karabiners or scaffold hooks into one D-ring
• DO NOT attach karabiners or scaffold hooks directly to a horizontal lifeline
WARNING: ALWAYS follow the manufacturer's instructions supplied with each system
component.
Proper alignment of the scaffold hook under load
• The scaffold hook must be installed so that the loads are applied in the area designed for greatest
strength (see marking on the product and Fig. VII)
• The anchorage or anchorage connector should be seated in the radius of the scaffold hook
opposite the Gate (4)
• DO NOT apply loads across the Gate (Fig. VI)
• The scaffold hook must be able to move freely and without interference during use ANY
constraint or external pressure is DANGEROUS (Fig. VI)
• Be aware that some equipment combinations may reduce the effective strength of the scaffold
hook. DO NOT connect to wide straps
Note: Regularly check connections with other equipment in the system during use, and ensure
various system components are correctly positioned with respect to each other. This may save
your life!
Rescue plan
WARNING: A suitable and sufficient risk assessment must be carried out before commencing with
any kind of work at height, or any work that requires the use of personal protective equipment (PPE)
as a control measure.
• The user must have a rescue plan and the means at hand to implement it
• The plan must take into account the equipment and special training necessary to effectively
conduct prompt rescue under all foreseeable conditions

Accessories

• Additional fall arrest equipment, workwear and other personal protection equipment is available
from your Silverline stockist
Maintenance
Note: All fall arrest equipment must be regularly inspected, cleaned and maintained by a
competent person, in accordance with local laws and regulations. Maintenance must be recorded in
a dedicated service record (see end of this manual).
WARNING: Carry out a visual and tactile inspection of all components, every time the
equipment is used. Carry out a detailed examination if the equipment has not been used for
some time.
Note: A thorough, detailed examination of the equipment must be carried out at regular intervals,
at least once annually, or more frequently depending on use.
WARNING: It is ILLEGAL to carry out any kind of repair or modification to fall arrest equipment.
WARNING: Should any damage be detected, remove the equipment from service immediately.
It must then be rendered unusable and discarded.
