EASY TO INSTALL JUST PUSH INTO THE HOLES AND SET YOUR SHELF ON TOP.
THESE SHELF SUPPORTS ARE VERY HEAVY DUTY AND HAVE A NICE SIZED PLATFORM TO SET THE SHELF ON AND ARE LOW PROFILE AND CAN HARDLY BE NOTICED WHEN IN PLACE!
THEY HAVE A HOLE IN THE CENTER TO ACCOMMODATE A # 5 SCREW (Not Included) THIS IS USED ONLY WHEN SHIPPING CABINETS TO STABILIZE THE SHELF OR IF YOU WISH TO KEEP A SHELF FROM PULLING OUT OF A CABINET OR BOOKCASE THAT IS OPEN WITH OUT FRAMES
