Product Specific Applications
Restraint: Diablo Cable Big Block SRL may be used in Restraint applications. Restraint systems
prevent workers from reaching the leading edge of a fall hazard. Always account for fully deployed
length of lanyard/SRL. Structure must withstand loads applied in the directions permitted by the
system of at least 1,000 lbs. No free fall is permitted. Restraint systems may only be used on
surfaces with slopes up to 4/12 (vertical/horizontal). Applicable D-rings: Dorsal, Chest, Side,
Shoulder.
!
WARNING
Use of equipment in unintended applications may result in serious
injury or death. Maximum 1 attachment per connection point.
Limitations
Fall Clearance: There must be sufficient
clearance below the anchorage connector
to arrest a fall before the user strikes the
ground or an obstruction. When
calculating fall clearance, account for a
MINIMUM 3’ safety factor, deceleration
distance, user height, length of lanyard/SRL,
harness stretch, and all other applicable
factors.
Diagram shown is an example fall
clearance calculation ONLY.
Swing Falls: Prior to installation or use,
make considerations for eliminating or
minimizing all swing fall hazards. Swing
falls occur when the anchor is not directly
above the location where a fall occurs.
Always work as close to in line with the
anchor point as possible. Swing falls
significantly increase the likelihood of
serious injury or death in the event of a fall.
Diablo Cable Big Block SRL recommended fall
clearance (does not factor in any potential
swing fall hazards; clearance numbers
specified based on lifeline installed in-line
with worker):
• Fall Clearance, LE Use: 17’-21’
• Fall Clearance, Non-LE Use: 9’
Personal Fall Arrest: Diablo Cable Big Block SRL may be used in Personal Fall Arrest applications
as a component of a MAXIMUM 1 Personal Fall Arrest System (PFAS). Structure must withstand loads
applied in the directions permitted by the system of at least 5,000 lbs. Applicable D-ring: Dorsal.
For all applications, worker weight capacity range (including all clothing, tools, and equipment):
• LE Use: 130-310 lbs.
• Non-LE Use: 130-420 lbs.
• Free fall, non-LE Use: Not permitted.
• Free fall, LE Use: Maximum 6’ free fall. SRL may be positioned a maximum 6’ below harness
dorsal D-ring or a maximum 6’ above anchor point.
*Eliminate Swing Fall whenever
possible! If Swing Fall exists,
always account for additional
fall clearance.
