Black Diamond Dogbone

The Straitjacket insert is a rubberized component designed to hold the bottom carabiner in a fixed, optimal position. This prevents the carabiner from rotating or flipping, ensuring it is always ready for you to clip the rope quickly and safely.

The 27 mm width is a standard size for sport climbing dogbones because it offers a balance between durability and ease of handling. It is wide enough to be easy to grab when you need to pull on a quickdraw, yet light enough to keep your rack weight manageable.

While it is designed primarily for sport climbing, it can be used for trad climbing as well. However, keep in mind that the Straitjacket insert is specifically optimized for sport quickdraws where you are clipping a rope into a fixed carabiner.

You should inspect your dogbones regularly for signs of wear, such as fraying, discoloration from UV exposure, or stiff, brittle webbing. If the stitching shows any signs of abrasion or if the webbing has been exposed to chemicals, it is time to retire the gear.

Yes, polyester is an excellent choice for dogbones because it is highly resistant to abrasion and does not absorb much water. This makes it a reliable, long-lasting material that maintains its strength even in varied outdoor conditions.
