DMM now manufacture Kwiklock, Locksafe and Durolock versions of the Ultra O, ideal for assisted braking devices, pulleys, swivels and shackles. As evolutions of the classic carabiner, the oval connector range now also offers the compact PerfectO and the larger AmericanO for when more volume is required.
The AmericanO is DMM's first ANSI (American National Standards Institute) compliant true oval connector—ideal for those working at height and needing an oval that can be used within the ANSI proof loading constraints.
The non-locking PerfectO provides colour coded options as a racking carabiner for trad climbers using Wallnuts, Alloy Offsets etc.
While the oval shape provides stable loading characteristics for industry practice, the same silhouette can be seen in miniature with the popular XSRE and XSRE Lock (non-PPE) accessory connectors.
As Mark points out, “we have a whole family of oval shaped carabiners now, which I believe is indicative of how versatile the shape is. The oval accommodates basic beginner systems as well as advanced techniques, offering a broad platform that will accommodate all sorts of systems when used in the field. The reversibility and the option to rig ovals back-to-back is also certainly a reason for its popularity.”
With the relationship between DMM and Treemagineers continuing to grow, the development of the oval carabiner is far from over. “If I had to put my finger on something which stands out in our collaborations with DMM,” says Mark “it’s that the products are so well thought out and designed.” Working together to design new gear and make improvements to classic pieces of equipment, DMM and Treemagineers have developed a range of connectors and an industry standard oval carabiner which is an integral element in the wider evolution of tree care kit.
