We have taken the confusion out of ordering pool fence by simplifying the process. All you need to know is how many sections of pool fence you need. To order simply count the number of fence sections needed to enclose your swimming pool. A fence section equals one top ledge or the distance between 2 upright posts. Remember to account for ladder openings, pool decks etc. Example: To completely enclose a pool with 16 total top ledges or 16 upright posts, it would take 16 sections of pool fence. Now if this same pool had only a typical pool ladder or step system for access, it would require 15 sections of pool fence to enclose the pool.
