Bliss Climbing Tech - Gate Bumper and Spine Bumper
Description
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).

2- Gate Bumper in Use
Verified ownerThe gate bumper really allows me to have better safety, less concerns, and overall a better flow experience while soloing in the mountains. It's a great tool that gives you strong control over your carabiners, and a superb feeling for gloved handling of your gates.
Verified ownerAs one of the company owners, I may be biased, but I truly enjoy this product and have it on most of my carabiners for testing. The Gate Bumper is especially helpful in preventing accidental gate loading when falling onto a device or bolt hanger without notice—and without the ability to tend the carabiner. This makes it particularly useful in general climbing, rope solo, and running belay situations, or anytime your hands are otherwise occupied and the carabiner needs to catch a fall. While some devices and carabiners have a predictable loading pattern without the need for the Gate Bumper, the Gate Bumper is my go-to solution, and I love it! Plus, the added grip on the gate is both convenient and comfortable.
