"Simple solution to a perennial problem. When you need to leave space around the pipe, to allow some pipe movement when removing a radiator, this collar is perfect. Clips together nicely and hides the hole without being too big and obtrusive."
"Simple. cheap, effective and reasonable to look at. Does the same job as collars costing ten times the price. Lacks pretty patterns and firmness (which leads to brittleness and breakage). All in all a very useful product."
