Pool fence in Puerto Rico comes in standard 4' or can be ordered in 5' tall as well. The most common height is 4' tall as this American Academy of Pediatrics recommends that every pool has a pool safety fence as well as a self closing, self latching and lockable pool safety gate. The gate portion of a pool fence system is the portion that receives the most use because of the traffic flow. This in and of itself simply makes it very important to pay close attention to the construction of the gate when making the purchase of your pool fence system. The gate should be reinforced in as many places as possible (most styles are dependent on the fence system itself however the better gates are independent, in other words if you take the fence out the fence will stand on it's own) and a bottom bar reinforcement is the preferred and gold standard of the industry. Be careful of marketing gimmicks when it comes to making your decision on what company to use. There are a lot of "here today, change companies tomorrow" businesses out there, especially here on the island. Ask how long they have been in business and how long they have been selling the same brand and working with the same manufacturer. This should shed some light on who and what you may be entering into an agreement with. Above all, make sure your pool gets protected sooner than later.
