Prevent Unwanted Carabiner Loading with the Gate Bumper (red) and the Spine Bumper (blue)!

Concerned that your device might load against your carabiner gate or other weird way? Stay safe with the Gate Bumper and the Spine Bumper!

Key Features:

Universal Compatibility: Designed to work with nearly all carabiners and devices.
Prevents Gate Loading Issues: Many devices and carabiners can interact unpredictably, causing both cross-loading and lever-loading of the gate. The Gate Bumper effectively prevents these issues, ensuring reliable performance.
Added Grip on the Gate: Provides extra grip, making it more convenient and comfortable to handle the carabiner, especially in challenging conditions.
Extensive Testing: We tested the Gate Bumper and Spine Bumper with popular devices such as the Petzl Micro Traxion, Mini Traxion, Rescucender, TAZ LOV3, Edelrid Spoc, Climbing Technology Cric, Fixe and Petzl Bolt Hangers. Carabiners used in testing include the Petzl OK Triact and Screw, Petzl Attache and William Screw, Camp Steel Oval, Climbing Technology Tech Pillar Pro, and Black Diamond Nitron Screw. The Gate Bumper solved issues in all tested combinations—and many more!

Important Note: While the Gate Bumper and the Spine Bumper prevents unwanted loading, it does not stop “clean cross-loading.” It’s an excellent choice for applications such as Top Rope Solo, leader protection in simul climbing, and general climbing. However, for Lead Rope Solo, we recommend a special carabiner (details in table below) or a different solution, as impact forces may exceed carabiner cross-load ratings (typically around 7kN).

Technical Details

Crafted from 3D-Printed TPU for Optimal Durability

The Bumper’s 3D-printed TPU construction offers exceptional abrasion resistance while remaining flexible enough to fit a wide range of carabiners.

Weight: Only 3.5 grams, it adds virtually no weight to your setup.

Color Update: The new color is translucent blue, crafted from a superior, softer TPU for enhanced performance. The turquoise version is now considered a vintage item.
