Nylon 26mmWorkhorse slings. Nylon 26mm slings carry a 30kN strength rating and are an ideal durable sling option. Nylon slings are wider and heavier than Dynatec slings. However, it is a good all round material that withstands repeated flexing better than Dynatec, has greater shock absorption, is less expensive and has a higher melting point. This makes nylon slings appropriate for heavy use by outdoor centres and rescue teams.
