Product information & specifications
DMM Ultra O Locksafe Carabiner 3 Pack
The DMM Ultra O Locksafe Carabiner 3 Pack is the ultimate all-round connector for arborists, rope access technicians and rescue professionals. Designed with a fully symmetrical oval shape, the Ultra O provides perfect balance and centralised loading for devices such as pulleys, swivels, ascenders and assisted braking systems.
The rounded rope basket allows attachments to self-centre under load, reducing unwanted movement and improving system stability. This makes the Ultra O particularly effective in complex climbing systems, rigging setups and rescue configurations where multiple connection points are used.
Available in a Locksafe auto-locking gate configuration, this 3-pack also offers the option for custom colour personalisation and marking, making it ideal for team identification or organised kit management.
Key Features
- Symmetrical oval design for optimal device alignment
- Ideal for use with pulleys, swivels, ascenders and braking devices
- Self-centring rope basket improves load stability
- Reduces unwanted movement and cross-loading
- Locksafe auto-locking gate for maximum security
- Keylock nose for snag-free connection
- DMM Taperlock technology for increased gate strength
- Available as a 3 pack with custom colour options
- Suitable for arboriculture, rope access and rescue systems
Why Choose an Oval Carabiner?
Oval connectors are widely used in arboriculture and rope access because they allow equipment to sit centrally. This ensures even load distribution and reduces the risk of twisting or instability within your system.
The Ultra O’s symmetrical basket means devices naturally align correctly without needing to rotate the carabiner, making it ideal for use with:
- Pulleys and rigging systems
- Mechanical ascenders and descenders
- Swivels and shackles
- Pre-rigged rescue setups
Gate & Safety Technology
The Ultra O features DMM’s patented Taperlock nose, which increases strength at the gate interface while providing a clean, snag-free connection when clipping ropes, slings or hardware.
The Locksafe gate requires three distinct actions to open, significantly reducing the risk of accidental gate opening during use. This makes it ideal for professional arborist and rope access environments where safety is critical.
Captive Bar Compatibility
Select Ultra O connectors can be supplied with a captive bar option. This ensures the connector remains correctly oriented and prevents movement within lanyard systems, helping maintain loading along the major axis for maximum strength.
Note: Captive bars are not load-bearing components.
