The corner protectors I ordered were for the elderly residents at my reitrement development where I am the Manager. I have positioned them on the two front corners of a couple of industrial sized metal refuse containers as one relative recently brought her head up quickly having bent down to pick up a rubbish bag to load into the container and gashed her head badly on the very sharp corner. These sturdy rubber protectors are now in place and give me peace of mind that this nasty accident won't happen again. I applied a lot of Superglue in order to get them to stick and this has worked. I therefore recommend this product and would add that delivery was extremely prompt. No complaints on any front. Thank you!
