These hooks are designed to be the interface or mount between a Duronic BPS projector screen (i.e., those that have a model number starting with the letters "BPS") and the MDF rail that goes over the front windows of a Swift caravan (note other make caravans may have a similar rail/shelf). The mounting hooks are the exact profile to fit over the top bar of a Duronic BPS screen and can be slid along the length of the bar as appropriate.

Each set contains 2 hooks to perfectly suspend a screen from the shelf.

These may be compatible with other projector screens if the top bar is 20mm in diameter or less. Pictures shown are with the BPS40/43 screen.
