As opposed to a traditional shock pack, PRO-Stop™ one-piece, shock absorbing lanyards are made from a polyester tubular web. Featuring an integral energy absorber, durable webbing and plated alloy steel hardware, the PRO-Stop™ delivers strength and is corrosion resistant. Plus, its unique inner core immediately begins to extend and absorb energy during a fall, limiting arresting forces to safe levels. Available in various styles, lengths and hooks options to fit your specific jobsite needs.
