Installation of anchor point
Before anchor point
A-165
is installed, it must be stored in a place which is: clean, free
from any vapours of corrosive substances, and in conditions preventing its mechanical
damage. Also please take into account environmental conditions present in the place of
installation which may cause corrosion of anchor point and fasteners.
Installation of the anchor point must be carried out in accordance with rules of fixing on
steel structures. For fixing use screws M10 with a length greater than 50mm and strength
class of no less than A2/70.
Installation of anchor points should be carried out in accordance with guidelines specified
by the manufacturer of these elements.
Follow general rules for use of personal fall protection equipment in accordance with EN
795:2012.
Heights of anchor point installation are described in item 7 of the manual.
It is recommended to install the anchor point flush with the cast reinforced concrete, then
it will be not necessary to add deflection of ribbed bars to deflection of the whole system.

Installation of anchor point
A-165
It is advisable to install the anchor point as close to a reinforced-concrete structure as
possible. The aim is to eliminate the need of additional calculation of deflection of ribbed
bars.
If it is necessary to install the anchor point higher, in calculations of SAFE FREE SPACE
UNDER USER add value X for direct connection with energy absorbing and connecting
components and value 2X for installation with use of horizontal lifelines.
Figure 4. Recommended installation of anchor point
A-165
x – height at which anchor point is installed above concrete structure.
In justified cases (no possibility of installation due to formworks, concrete splashes set on
bars, formworks located above concrete level, etc. it is acceptable to install anchor
points for:
Direct connection of anchor point
A-165
to energy absorbing and connecting component
– height of up to 1500mm above concrete structure for ribbed bars with core diameter
18–32 mm.
Figure 7. Installation with horizontal anchor systems
– height up to 1100mm above concrete structure for ribbed bars with core diameter
28–32mm. Figure 8
In order to install the anchor point it is necessary to check the depth of bar anchoring in
the concrete structure.
The bar should be anchored in concrete to a depth of more than 700mm.
Diameter of ribbed bar to which the anchor point will be installed should be greater than
18mm and no greater than 35mm measured at outer diameter of the bar (core 32mm).
Apply slot of anchor point at ribbed bar and turn by 90 degrees (Figure 5)
Figure 5. Installation of anchor point on bar
While holding anchor point
A-165
tighten both mounting screws (Figure 6) using torque
wrench (1) to 30-40 Nm. Then tighten lock nut to prevent the screw from unscrewing with
use of flat wrench 17mm (2).

Next, using torque wrench, tighten to 30–40 Nm.
If the anchor point is going to be used by directly connecting it to energy absorbing and
connecting components it is necessary to meet the following conditions Figure 7:
Diameter of ribbed bar core should be greater than 18mm.
Lower surface of anchor point
A-165
cannot be installed on the bar higher than 1500mm
above concrete structure surface.
