ISC Ultralink

The ISC Ultralink is a connector from ISC used to link components in climbing and rigging systems. It provides a secure, compact connection point where a carabiner may be bulky or awkward.

Where a connector link fits

Not every connection in a climbing or rigging system needs a carabiner. A connector link can be lower profile and less prone to cross-loading, which suits semi-permanent connections such as bridges, rope terminations, or device attachments.

Check the Ultralink's ratings, dimensions, and approved uses against your system before ordering. See more climbing hardware.

ISC is a UK maker of rope access and arborist hardware, including pulleys, rigging gear, and connectors. A connector link is the kind of part that often gets overlooked, but it carries the same loads as the rest of the system.

Use and inspection

Load a connector link only in the direction the manufacturer specifies, and make sure it is fully closed before loading.

Life-support gear must meet the applicable standard, follow ANSI Z133 and the manufacturer's instructions, be inspected before every climb, and be used only by trained climbers. Retire a connector that is cracked, worn, deformed, or has been shock loaded.

If in doubt about compatibility, ask the manufacturer.

Check that the gate or closure works smoothly and fully locks. Clean and dry hardware after use, especially after exposure to sap, mud, or salt. Retire any connector if you're unsure of its condition. A spare connector costs little compared to the consequences of a failure.
