I have seen advertised in supply catalogs a piece of equipment called
 a slatted rack.  The outside dimensions are the same as the hive body,
 about 2 inches high and has a wide (4-5") board across the front inside
 followed by about 10 or so .75" slats equally spaced to fill out
 the rest of the area.
 
 It says it's to prevent swarming.
 I really don't understand how. Does anyone out there know?
 How does it go on the hive?  Does the wide board go towards the front?
 What about the extra space it creates, won't the bees build
 comb on the bottom of the frames?  Is the extra space given to the bottom
 board or to the hive body?
