This is a must have purchase for us when we purchased our 16ft trampoline. . It hooks right on to the side and creates like a triangle brace for people to use to get on and off the jumper. I feel much better with my children using this and it has held up for around 2years perfect. If you need to remove it, you just lift up. Helps with mowing or keeping younger kids from climbing. It supports over 300lbs easily.
