I ordered these 3 months ago and they seem to have lapped the globe many times before making their way to me, 3 different con note nubers, delays beyond reason, but they finally arrived after 22 follow up emails.
They are simply a screw driven clamp to drop a nut or bolt into and then reach up inside the impssible location to save growing thoes 8" long spider fingers. They are in 3 sizes up to 300mm and whilst yet to try them in anger, am already looking forward to the need. They were off Fcaebook somewhere, cost about $30 including shipping.Clamps 3.jpgClamps 2.jpgClamps 1.jpg
