The Ultra D is similar in size and weight to the Ultra O; however it is stronger and has a slightly bigger gate opening.
The open D shape gives a lot of internal space within the biner, which makes it useful for setting up belays. Its also finding favour as a perfect partner to a belay device.
- D shaped locking biner
- Strong and lightweight I-Beam construction
- Shrouded nose
- Generous rope radius
- Can be supplied with a captive pin to hold the biner in a specific position and prevent cross-loading
