The Petzl SM’D Carabiner is a compact, lightweight aluminum carabiner designed for workers at height and climbers who want to minimize equipment weight without compromising functionality. Its D-shaped design is particularly well suited for attaching devices, while the compact frame provides easy handling and efficient positioning.

Available from Backpackers Outdoor, the Petzl SM’D is a versatile choice for connecting belay devices, pulleys, lanyards and compatible technical equipment.

Compact D-Shaped Design

The D shape of the Petzl SM’D helps keep the load positioned effectively and makes the carabiner especially suitable for connecting devices. Its fluid interior reduces the likelihood of equipment or rope catching on the frame and allows the carabiner to rotate smoothly during use.

The Keylock system eliminates the traditional hook at the gate and helps prevent the carabiner from snagging on ropes, anchors, harness equipment loops and other gear.

Lightweight H-Frame Construction

The SM’D uses an H-shaped cross-section that provides an excellent strength-to-weight ratio while helping protect the product markings from abrasion. Depending on the selected configuration, the carabiner weighs between 40 g and 55 g, making it a practical option when reducing equipment weight is important.

A dedicated hole allows a TIBLOC or MICRO TRAXION to be connected to the carabiner with a cord, helping reduce the risk of losing these compact devices during use.

Locking Options for Different Uses

The Petzl SM’D is available in different configurations to suit various applications:

• TRIACT-LOCK: Automatic locking system with triple-action gate opening.
• SCREW-LOCK: Manual screw-lock system with a red band that provides a visual warning when the carabiner is unlocked.
• Without locking system: Designed for easy clipping during progression using climbing techniques.

This range of configurations allows users to select the SM’D according to whether they need an automatic locking connector, manual locking or quick clipping.
