APPLICATION
SafeBloc is designed for rigging applications
as an alternative to traditional block pulley.
This product must not be loaded beyond its
strength rating, nor be used for any purpose
other than that for which it is designed. Prior
to each use ensure the SafeBloc is securely
anchored via conforming arborist rigging
sling. SafeBloc is not intended for climbing
and therefore not designed for life support.
PROPER USE
Only the loading shown as “OK” is allowed. Always verify proper positioning of your system and
components. Equipment must be free to align with the load, any restraint is dangerous.
• DO NOT CONNECT SafeBloc to sling or
spliced rope with a snap or other metal
connector.
• SafeBloc is only to be used with a profes-
sionally spliced sling.
• Ensure you have sufficient amount of rope
to land targeted load onto landing zone.
• DO NOT OVER ESTIMATE the strength of
your anchor point(s) or ropes.
• Positioning of the anchorage point for
safe fall arrest and this must take into ac-
count the fall distance including the rope
stretch so that obstructions (such as the
ground) may be safely avoided.
No responsibility will be accepted by Notch Equipment for damage, injury or death resulting from
misuse. Some examples of misuse are shown in the illustration and many other types of misuse also
exist; it is impossible to predict them all. User personally assumes all risks and responsibilities for
all damage, injury or death which may occur during or following incorrect use of this product in any
manner whatsoever.
COMPATIBILITY
Verify that product is compatible with other
elements of the system in your application
(compatible = good functional interaction).
SafeBloc is ONLY intended to be used with
arborist rigging ropes with the maximum di-
ameter of 3/4” (19mm) of three strand, double
braid or solid braid construction.
SafeBloc is compatible and can be used in
conjunction with lowering devices such as
GRCS (Good Rigging Control System), Portaw-
rap, Hobbs Device, and Rigging Bollard. It’s
the user’s responsibility to ensure that he/she
understands the correct and safe use of this
product.
INSPECT BEFORE & AFTER USE
Immediately before use read and understand
all instructions for use, visually and function-
ally inspect to ensure the product is in ser-
viceable condition and operates correctly.

marks, corrosion, etc. Inspect the spliced rope
for wear [see Maintenance & Storage].
In addition to inspection before, during and
after each use, a detailed inspection by a
competent inspector must be done at least
every 3 months or more frequently depend-
ing on amount and type of use. Make a copy
