FEATURES Besides the obvious fact that stainless steel is much harder than other metals used by our competitors, it has several other features. First, the stainless steel spring is stronger than the other safety fence latches. Secondly, in order to improve pool safety, it is lockable. Each latch is designed to accept an optional keyed padlock. This feature will help keep your pool fence safer and help you promote drowning prevention. Finally, because our latch now matches our stainless steel screws, we believe that the over all look of our pool fence is much improved.
