B.S. National Entrance Block, Cedar
The Entrance Block fits snugly in the opening between the bottom board and your first brood chamber to control the size of the entrance to the hive.

Very disappointed with these (I bought two). They came and both are bent, giving the impression they were made of damp wood and have bent since drying out. They arn't much use for stuffing into the entrance of a hive, anyway.
Arrived quickly but unfortunately broken as not packaged very well. A replacement also arrived quickly all in one piece, thank you
Arrived promptly; like the two sizes of opening.
five stars thank you will use again
