When choosing a dead bolt, you need to find out whether to go for a double or single cylinder model. When you have a double cylinder dead bolt, you require a key to unlock and close from both inside and outside the door. Alternatively, you can lock or open a single cylinder from the inside devoid of using a key. The double cylinder is the better alternative for your business particularly if your doors have glass or windows. This will put off someone breaking the glass to open the door from the inside.
When selecting the lock, you have to think about the issue of security. It is imperative to note that a double cylinder one can make it hard to exit the building fast in case of an emergency. It also helps to keep in mind that modern windows are made from tough glass that is not easy to break. Get the services of a specialized locksmith arlington tx to make sure proper installation.
