I ordered them for a table my great-great-grandfather made with his own hands. They are beautiful and heavy. The table already had holes for the wheels, so I just put the table on those wheels. You look so good! This is everything I hoped for! They won't screw into the table legs, but they won't move this table. So I can't make a note to install. However, if you have the right tools, I don't see how difficult this would be. This table is made from solid walnut and these casters support its weight very well.
