The fence is only effective if the gate and gate hardware are in good working order.  Checking the pool gate is crucial for drowning prevention,
yet only 30% of pool owners do this once a year.

Please inspect your gates, it could save a child’s life. ❤️

May is Check Your Pool Gate Month!

Fencing is the first layer of protection in reducing child drowning. Check your pool gate month is the time to become involved in your community to help prevent child drowning. Get involved by reminding your customers, community and employees of how important gate latches and fences are, and the vital need to ensure pool fences, gates, latches and hinges are secure and in top working order.

We installed this in a school handicap restroom, contact us for more information.
