Petzl Sm'D Ultra-light Triact 3 Way Carabiner - Yellow

Petzl Sm’D Ultra-light TRIACT 3 Way Carabiner – Yellow

The Petzl Sm’D Ultra-light TRIACT carabiner is a compact aluminium connector designed for professionals working at height who need to minimise weight without compromising reliability. Its asymmetrical D shape is particularly well suited to attaching devices, helping maintain stable alignment and predictable loading during use. With a clean internal profile and lightweight construction, the Sm’D supports efficient system management in arboriculture, rope access, and work positioning applications.

Compact design for efficient device attachment

The D-shaped profile of the Sm’D is optimised for connecting mechanical devices, allowing loads to sit close to the spine for improved stability. This shape supports consistent major axis loading, helping devices remain correctly oriented during movement. The compact size also makes it easier to manage in tight systems where space and clarity are important, particularly when multiple connectors are in use.

Secure automatic locking with TRIACT system

This version is fitted with Petzl’s TRIACT automatic locking gate, which requires three distinct actions to open. This mechanism helps reduce the risk of accidental opening during work, while still allowing smooth, controlled operation when deliberate clipping or unclipping is required. The Keylock nose design eliminates snagging on ropes, slings, or hardware, supporting clean transitions within the system.

Lightweight construction with practical durability

Manufactured from aluminium with an H-shaped cross-section, the Sm’D achieves an excellent balance between strength and weight. At 55 g, it helps keep overall system weight low while still offering a major axis strength of 23 kN. The H-profile also helps protect markings from abrasion, supporting long-term legibility during regular professional use. An integrated hole allows accessories such as a TIBLOC or MICRO TRAXION to be connected, helping reduce the risk of dropping small components.
