Why do some doors have vault pins?
Vault pins are required for ‘assembly on site doors‘. Assembly on site doors are exactly as the name describes. The door is assembled at the place of installation (your home). The door is fastened to a multi piece sub frame through two screwed on hinges. In order to compensate for this weak link and to prevent the hinges from simply being removed to gain entry, vault pins must be installed to prevent the door from being separated from it’s sub frame. Native Sun incorporates a unitized construction method. This is the strongest method of security door construction available on the market. When your door arrives at your home it arrives in one piece. All assembly is done at the manufacturing facility. Unitized construction means the door is fastened permanently to a steel one piece sub frame with three tamper proof, welded on hinges. There is no need for secondary measures such as vault pins. You simply can not find a safer more secure door than a Native Sun security screen door.
