Then they installed a wall which provided about 3 foot of clearance. Fun times. Best thing to do is to make sure they haven't been charged for a few days as they will contract just enough. Also you'll want to make sure the temperature of the room is around 70 degrees or cooler as this will also help with the sliding them out. You may end up with a couple of stubborn ones and for that I came up with this rudimentary rig consisting of 2x4's to winch them out with a ratchet tie down. In the attached picture the rig is not attached to the wall. I needed just enough room to winch them out about 2/3rds of the way and then they came out. Did this with just two people. One person can easily lift them. Should be able to zoom in on the picture for details. If you need more info feel free to call me.
