Flipper Shelf Supports

Drill 5mm holes in both the shelf, which should be at least 14mm thick, and the carcass, sized to accept either the smooth pin dowel or the Euro screw dowel.

The plastic insert seats inside a hole drilled into the shelf end so nothing shows on the top or underside, while a matching dowel mounts in the carcass; the insert's spring flippers grip the dowel to hold the shelf firmly in place.

The screw dowel threads into the carcass for a more secure installation, while the pin dowel is a smooth press-fit for standard 5mm holes; choose the screw dowel where the shelf will see more frequent loading or repositioning.

Each package of flipper shelf supports includes 20 plastic inserts and a matching number of dowels, enough for multiple shelves in a typical cabinet run.

Yes, both dowel styles are sized for standard 5mm holes, the same size used by common shelf-pin systems, so installation doesn't require specialty drilling.
