How do the pool fence posts lock into the deck?

Inside of the holes for your fence are our plastic sleeves that we designed with a groove running from top to bottom. Our fence posts with Lock-in-Deck, include a screw/pin at the bottom which fits into the groove of the sleeve. You will insert your post into the sleeve, aligning the pin/screw with the groove, and twist straight at the end to lock your post in place. To unlock, you untwist and pull up to disable Lock-in-Deck. This patented feature is only offered by Protect-A-Child. Learn more about our Lock-in-Deck and other added layers of protection on our SureSafe Features^TM page.
