Reduces forces by as much as 50%-80%. Rugged 6' lanyards feature a special shock absorbing inner core surrounded by a super-strong outer jacket. When a fall occurs, the outer jacket extends full length and acts as a backup web lanyard, while the inner core extends to reduce force. Unique warning flag pops out to indicate when lanyard has been involved in a fall and should be removed from service. Available in single or dual leg. Complies with OSHA 1926.502, ANSI A10.14, Z359.1, and CSA Z259.11 Standards.
