Aluminum plate for an abseil ladder. It was used for aid climbing for about 3 years in the past and has scratches and dirt. Five of the rivets on the holes for the plate's sling are missing. I think it's easy to reattach them. Also, black sandpaper-like tape is attached to the surface of the plate. This prevents the shoes from slipping and is very convenient, so I haven't removed it. It can be easily peeled off, so please remove it if you don't need it.
