ISC Ultralink Large



The ISC UltraLink Large is a revolutionary rope link transforming how rope is connected and redirected. This groundbreaking innovation incorporates a removable pulley for added versatility while prioritizing safety and efficiency in its design. With the user-friendly SafeLock mechanism, unlocking the ISC UltraLink is effortless, requiring three deliberate actions with just one hand. Built to withstand rigorous demands, it offers impressive strength, with a minor axis MBS of 25kN (5620lbf) and a significant axis MBS of 30kN (6744lbf), which increases to 40kN (8922lbf) when used with the pulley wheel. Crafted from corrosion-resistant Stainless Steel and a lightweight Aluminium Sheave, its unique bowed frame shape ensures correct loading, while the high-visibility sheave makes locating the wheel easier. Experience the future of rope connections with the ISC UltraLink.

  • The link is designed to be loaded across the major and minor axis.
  • Ensure that the locking mechanism is engaged, prior to use.
  • The link may be used with/without the sheave. It is beneficial to use the sheave whenever possible, in order to centralise the load across the major axis
  • Ensure that the device is installed with the axle head and Safelock button facing away from the structure and clear of any obstructions which may cause accidental depression of the Safelock button.
  • If connecting the rope termination (e.g sewn/spliced eye) to the frame, it is recommended that the sheave is used on the axle
