Product review (1 stars): they are very good quality. BUT
Yes, they are very good quality.  BUT, no, they do not have an open space to fit around the heating elements.  They have a hole, but the hole does not do me any good.  My burner elements are connected to my stove and the elements need an open space to slide into.  These have been sitting in the box for a few years now because I am always very negligent in returning things.  I thought about going to the local two-year college to see if their welding class can cut a space for my burner elements.  But I am a busy person and have not made it a priority.
