Perfect for when you're camping with full hookups. This keeps your sewer hose off the ground and up just enough to drain while camping. It spreads easy and evenly. I like not having to put blocks, metal hooks, or something else to set the hose on. This is quick and easy. It's very durable plastic and if needed easy to rinse off. It comes with an orange piece that hooks onto it to keep it together to make it great for storing. We have a gray tank in front and gray and black in back. We use two sewer hoses when camping with full hookup. I bought two of these so one is under each sewer hose. The look of these is just "neater" versus tacky like my uneven blocks were. They are very stable once put in place whether on concrete or gravel campsite.
