M01936 Country Rubes Observation Board
Universal Grid Observation Boards for Screened Bottom Boards from Country Rubes made out flexible Polyethylene material for durability and ease of cleaning. Can be cut to fit any bottom board with a paper cutter or scissors and the slot makes it easy to remove with fingers or a hive tool, no need for string. They are chemical resistant and can be used to cover screens when using acids or fumes. Bright white and large grids - easy to see and count mites. Non-absorbent - will stay sticky (use oil, spray or petroleum jelly) until covered with debris, as opposed to just a few days. Nothing will stick to it - easy to clean by scraping off or use soap and water. Durable, easy to bend but will not break. Not UV protected, cannot leave out in the sun.
