If you have the DII with the color head, the drawer slides into place in it's own slot just under the bulb. Heat would be a factor only in VERY long exposures--don't use f32. The drawer is about 3/8" deep, so there's plenty of room left over for a sheet of black cardboard to hold your cut-down filters. I paid $450 for my DII with color head--no great bargain, but I am thankful every time I use it. It is a big improvement over the old DII with the variable condenser shelves which I got for $100 15 years ago. On that one I merely peeked inside the condenser cabinet and placed the filters on whatever shelf I wasn't using. I never considered movement, never slammed the door, and never saw blurring.
