ISC UltraLink – Small & Large

Description

The ISC UltraLink changes how you connect and redirect ropes, blocks, and hardware in tree work, rigging, and rope access systems. Built with professional users in mind, this link combines secure locking, a removable pulley, and durable construction to improve workflow and reliability on the job site.

UltraLink features a removable aluminium sheave wheel that lets you use the link as a block when needed. This adds flexibility to your rigging setup and helps you manage loads with mechanical advantage. When you don’t need the sheave, you can remove it and use the link as a strong connector.

Safety is central to the design. UltraLink uses ISC’s SafeLock mechanism, a deliberate three‑action lock you can open with one hand using thumb and forefinger. The button sits inside a guarded recess to reduce the risk of unintentional opening while working.

UltraLink delivers impressive strength. It has a minimum breaking strength (MBS) of 40 kN when the pulley wheel is fitted. That means you get robust performance for heavy rigging systems and frequent use. The bowed frame shape also encourages correct loading, especially on the minor axis, and helps keep forces aligned on the strongest parts of the link.

ISC builds the UltraLink body from corrosion‑resistant stainless steel with a polished finish and a high‑visibility aluminium sheave that stands out if dropped in foliage or on the ground. The link comes in two sizes (Small and Large) so you can match it to your setup, rope size, and rigging needs.

Whether you use it to tie hardware into your rigging line, create short connection points between devices, or add a quick redirect in a mechanical‑advantage system, the ISC UltraLink offers versatility, strength, and reliable locking you can trust on demanding climbs and canopy jobs.
