THIS IS FOR 4 ENTRANCES BULK PACKAGED WHICH SHIPS FREE TO DOMESTIC U.S. DESTINATIONS. I bundled them this way because the shipping for one entrance costs the same as 4. I decided to make a new compact sliding entrance because my first one may have too many uses for some beekeepers. This one has three main positions and two half positions so it’s a queen excluder, vent and full open with mouse guard. It can be slid to halfway between the queen excluder and vent or open position and vent to reduce the entry and help weaker colonies to defend against robbing. This entrance allows the use of a top board for the bottom board thus saving on inventory. The installation is straight forward, but illustrated instructions are included and all screws are provided. The entrance can be placed at the top or bottom of the box(s) whichever is preferred. DRILL, SCREWDRIVER AND BOX NOT INCLUDED They are made from durable nylon in California, as are all the products I make. SPEHAR Products, Imagination + Unfair Advantage.
