This is a rope pulley made by ISIC APE GEAR. It is a professional-grade product from a manufacturer for arborists in the UK. I purchased it from Oniwaban about a year ago. I used it once, but I am selling it because I have an impact block and two other small-sized blocks, so I haven't used it. There are some minor scratches from use, but there is no significant damage or deformation, and it is in a condition that poses no problem for practical use. *Please check the photos for the condition. Please feel free to comment if you would like additional photos! From the body engraving: Model number: RP051 Rope diameter range (mm): Up to 16mm (15/8") Working line up to 25mm (1") topping strap (WLL) Working Load Limit (kg): 2000 Pulley wheel color: Orange Anchor wheel color: Red Body finish: Powder coating Color: Red Weight: 1490g CE approved This is a high-strength pulley that can be used for tree climbing, rope access, rescue, rigging assistance, etc. It is compact yet very rigid, and the pulley rotates smoothly. Currently, it is a model that is difficult to obtain as it is not widely distributed in Japan. How about it for those looking for professional-grade gear? Please purchase only if you understand that this is a used item.
