Security Door Locks
Let us take a look at this vision. A larger door handle but moved to the centre of the door where a lock mechanism will push iron pins into three sides of the frame (the top and both sides). The pins are hidden inside the door and the lock could be formed to push each pin simutaneously(sp?)into guard plates inserted into the door frame.

Reward: To sing with the DOORS
