There are lots of eyelet options to fit on to this. M10 , M12, M14 .just simply clamps onto the Keira on a marquee. I can't seem to find an eyelet on Thomann for these but was able to find in my local hardware shop. I do wish and hope they bring one out with a high rating but for what I'm doing at the moment there perfect. I use m14 eyelets with them and the eyelet is rated at 500kg but the tentclamp is rated at 150kg so 150kg is the safe working load.
