Hi I am trying to remove metal snap in ceiling tiles, that are in a grid system. I want to remove them, repair some work in the ceiling, then replace them - with out them getting damaged. I heard that there is a special tool for this. Is this true? Can anyone tell me where to find such tool. I have tried local ceiling and drywall companies...no luck! From the description: the hand tool is about 8" long and has a handle on one end and a "hook" like on the other end. Thanks for your help and any information that you have would be helpful!
