Swimming pool nets and covers are used to keep debris out of the pool. The installation process for a swimming pool net or cover can vary depending on the type of net or cover you have. For example, if you have an inground swimming pool cover, you will need to remove all swimming pool ladders and handrails before installing the cover. You will then need to measure the pool and the pool cover and place the cover over the pool carefully so you do not snag or damage it
