!

Personal Fall Arrest: MK Edge SRL may be used to support a MAXIMUM 1 Personal
Fall Arrest System (PFAS) for use in Fall Arrest applications. Structure must
withstand loads applied in the directions permitted by the system of at least
5,000 lbs. Applicable D-ring: Dorsal.

• Standard applications: No free fall is permitted. SRL must always be positioned
at or above harness dorsal D-ring AND at or below anchor point.

• Leading Edge (LE) applications: Maximum 2’ free fall. SRL may be positioned a
maximum 2’ below harness dorsal D-ring or a maximum 2’ above anchor point.

Restraint: MK Edge 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.

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, 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.
