instructions may result in serious injury or death.
IF YOU HAVE ANY QUESTIONS ABOUT ANYTHING IN THESE
INSTRUCTIONS, THE EQUIPMENT, OR PROPER USE OF THE
EQUIPMENT, CONTACT WERNER CO. FOR MORE INFORMATION.
I. Before Using the Builders Grip Anchor
Before using this equipment the user should take certain steps to ensure
that it is in suitable condition and safe for use. Users must read and
understand these instructions. It is the employer’s obligation to ensure
that all users have been trained in safe work procedures as well as in the
use and limitations of fall protection equipment. All users should be aware
of and comply with all applicable OSHA, ANSI and local or regional
regulations concerning fall protection equipment and its use.
a. Inspect
Examine all equipment thoroughly, daily before use by the user,
and periodically by a competent person who is not the user.
1. Ensure that the Builders Grip Anchor is free from rust, corrosion
and any damage. Clean with warm soapy solution to prevent
damaging the Builders Grip Anchor or structure.
2. Inspect the Builders Grip Anchor to ensure there are no cracks,
dents or marks on the anchorage.

USER INSTRUCTIONS
4. Make sure labels are attached to the Builders Grip Anchor and
are legible.
5. Record the inspection date and results in the Inspection and
Maintenance Log
6. If inspection reveals a defective condition or abnormalities in
any of these areas, remove unit from service immediately. A
competent person should be consulted to determine if that item
is safe for continued use or if it should be destroyed.
IMPORTANT: If this equipment has been subjected to forces
resulting from the arrest of a fall, it must be immediately removed
from service.
b. Compatibility
Werner Co. equipment is designed for use with Werner Co. approved
components and subsystems only. Substitutions or replacements
made with non-approved components or subsystems may
jeopardize compatibility of equipment and may affect the safety and
reliability of the complete system.
Connectors are considered to be compatible with connecting
elements when they have been designed to work together in
such a way that their sizes and shapes do not cause their gate
mechanisms to inadvertently open regardless of how they become
oriented. Contact Werner Co. if you have any questions about
compatibility. Connectors (hooks, carabiners, and D-rings) must be
capable of supporting at least 5,000 lbs. (22.2kN). Connectors must
be compatible with the anchorage or other system components.
Do not use equipment that is not compatible. Non-compatible
connectors may unintentionally disengage. See inappropriate
connections. Connectors must be compatible in size, shape, and
strength. Self locking snap hooks and carabiners are required by
ANSI Z359 and OSHA.
c. Fall Protection Plan
Plan your fall arrest or restraint system before starting your work.
Take into consideration all factors affecting your safety at any
time during use. The following list gives some important points to
consider when planning your system:
Page 5
ENGLISH
1. ANCHORAGE: Select a rigid anchorage point that is capable of
supporting the required loads. See section II.b. The anchorage
location must be carefully selected to reduce possible free fall
and swing fall hazards and to avoid striking an object during
a fall. For restraint systems the anchorage must be located
such that no vertical free fall is possible. For fall arrest systems
OSHA requires the anchorage be independent of the means
suspending or supporting the user.
2. FREE FALL: Do not work above the anchorage level, increased
fall distance will result. Personal fall arrest systems must be
rigged such that the potential free fall is never greater than six
feet. Restraint systems must be rigged such that there is no
possible vertical free fall.
3. FALL ARREST FORCES: The assembled fall arrest system
must keep fall arrest
forces below 1,800 lbs.
when used with a full body
harness. Do not use a
Anchorages
SWING FALL
HAZARD
body belt for fall arrest.
4. SWING FALLS: Swing
falls occur when the
anchorage point is not
directly above the point
where a fall occurs. The
force of striking an object
CorrectIncorrect
in a swing fall may cause serious injury or death. Minimize swing
falls by working as close to the anchorage point as possible.
Do not permit a swing fall if injury could occur. Swing falls
will signicantly increase the clearance required when a selfretracting lifeline or other variable length connecting subsystem
is used.
5. FALL CLEARANCE: Make certain enough clearance exists
in your fall path to prevent striking an object. The amount of
clearance needed is dependent upon the type of connecting
subsystem used and anchorage location. See Fall distance
charts for shock absorbing lanyards or Fall distance for selfretracting lifelines for estimating fall clearance.

6. RESCUE: Should a fall occur, the user (employer) must have a
rescue plan. If a worker falls and is forced to remain suspended
for any length of time, physical damage to the body or even
death can result. For this reason Werner, OSHA, ANSI and
most local regulations require that a rescue plan and the means
to implement the rescue plan are in place before use of this
equipment.
7. AFTER A FALL: Any equipment which has been subjected
to the force of arresting a fall must be removed from service
immediately.
ENGLISH
Page 7
Warning:
Never connect more than one personal fall arrest or restraint system
to a single Builders Grip Anchor.
Warning:
Follow manufacturer’s instructions for associated equipment used in
your fall protection or restraint system
d. Training
OSHA, ANSI, and most local ordinances require that workers using
this product receive adequate training before use of this product.
These instructions and their entire contents should be a part of that
training.
II. Builders Grip Anchor Installation and Use
Warning:
Do not alter or intentionally misuse this equipment. Consult with
Werner Co. if using this equipment with components or subsystems
other than those described in this manual. Some subsystem and
component combinations may interfere with the operation of this
equipment. Use caution when using this equipment around moving
machinery, electrical hazards, chemical hazards, and sharp edges.
Warning:
Do not use this device if you are unable to tolerate the impact of
a fall arrest. Age and tness can seriously affect your ability to
withstand a fall. Pregnant women and minors must not use this
equipment.
a. Making Connections
1. Only use self-locking snap hooks and carabiners with this
equipment. Only use connectors that are suitable to each
application. Ensure all connections are compatible in size, shape
and strength. Do not use equipment that is not compatible.
Ensure all connectors are fully closed and locked.
PROPER CONNECTION
ENGLISH

2. Werner Co. connectors (snap
hooks and carabiners) are
designed to be used only as
specied in each product’s
user’s instructions. See
inappropriate connections.
BUILDERS GRIP ANCHOR
INAPPROPRIATE CONNECTIONS
A. B.
NO! NO! NO! NO!
D. E. F.
Werner Co. snap hooks and carabiners should NOT be
connected:
i. to a D-ring to which another connector is attached.
ii. in a manner that would result in a load on the gate. If the
connecting element that a snaphook or carabiner attaches
to is undersized or irregular in shape, a situation could occur
where the connecting element applies a force to the gate of
the snaphook or carabiner. This force may cause the gate
(of either a self-locking or a non-locking snaphook) to open,
allowing the snaphook or carabiner to disengage from the
connecting point.
NOTE: Large throat opening snap hooks should not be
connected to standard size D-rings or similar objects which
will result in a load on the gate if the hook or D-ring twists
or rotates. Large throat snap hooks are designed for use on
xed structural elements such as rebar or cross members
that are not shaped in a way that can capture the gate of
the hook.
iii. in a false engagement, where features that protrude from
the snap hook or carabiner catch on the anchor and without
visual conrmation seems to be fully engaged to the anchor
point.
iv. to each other.
v. directly to webbing or rope lanyard or tie-back (unless
the manufacturer’s instructions for both the lanyard and
connector specically allow such a connection).

vi. to any object which is shaped or dimensioned such that the
snap hook or carabiner will not close and lock, or that roll-
out could occur.
3. When using an energy-absorbing lanyard, connect the energy
absorber “pack” end to the harness.
b. Anchorage Strength
Depending on the application, the structure to which the D-Bolt is
installed must meet strengths as given below:
1. FALL ARREST: Anchorages selected for personal fall arrest
systems (PFAS) shall have a strength capable of sustaining
static loads, applied in the directions permitted by the PFAS, of
at least; (A) 3,600 lbs. (16kN) when certication exists (see ANSI
Z359.1 for certication denition), or (B) 5,000 lbs. (22kN) in the
absence of certication. When more than one PFAS is attached
to an anchorage, the anchorage strengths set forth in (A) and
(B) above shall be multiplied by the number of personal fall
arrest systems attached to the anchorage.Per OSHA 1926.500
and 1910.66; Anchorages used for attachment of PFAS shall
be independent of any anchorage being used to support or
suspend platforms, and capable of supporting at least 5,000 lbs.
(22kN) per user attached, or be designed, installed, and used as
part of a complete PFAS which maintains a safety factory of at
least two, and is supervised by a qualied person.
2. RESTRAINT: Anchors selected for restraint applications must
be attached to a structure capable of sustaining a static load
of at least 3,000 lbs. applied in any direction permitted by the
restraint system when in use. Each anchor installation must be
independently capable of sustaining this load. When more than
one restraint system is attached to an anchorage, the strengths
stated above must be multiplied by the number of restraint
system attached to the anchorage.
Warning:
Restraint anchorages may only be used where there is no possible
vertical free fall. Restraint anchorages do not have sufficient strength
for fall arrest. Do not connect personal fall arrest systems to restraint
anchorages.
3. WORK POSITIONING: The structure to which the anchor point
ENGLISH
is attached must sustain static loads applied in the directions
permitted by the work positioning system of at least 3,000 lbs., or
