this one continues to plague me.  I bought it for a spot on a wall with a radiator.  I know it does not look like it has much clearance (AND IT DOES NOT) but for some reason the Wayfair Chat person thought it had an 8 inch clearance.  I have it on a different wall, but it is not serving the purpose I bought it for.  I may have to resell it.  There must be one that will work for a wall with baseboard radiators . . . .
