Thank you for viewing. These modified parts for the Unicender are items personally imported directly from Richard Mumford in the United States. The Unicender itself is a highly versatile climbing device, known for its quick attachment and detachment from the rope, and its compatibility with various climbing techniques. This modification further enhances the climbing device! The modification to Richard's specifications maximizes temporary rope locking and friction reduction. It can be said to be the most historically significant climbing device as an SRS mechanical device. 【Standard Specifications Features】 ・Easy rope attachment and detachment compared to other devices. ・Compatible with thin ropes (from 11mm). ・No need for adjustment based on rope diameter. ・Usable as an MRS-dedicated device, not a simplified MRS like other SRS-only devices. ・Quick and easy switching between MRS and SRS. ・Easy and safe to use in conjunction with other SRS-only devices (always able to back up the working end of the rope). ・Very simple and easy-to-use structure. ・Compatible with various techniques. 【Standard Specifications】 ■Weight: Approximately 310g ■Usable rope diameter: 11mm to 13mm ■Material: Aluminum ■Target: DdRT and SRT compatible *Please judge the condition of the product from the photos.
