To eliminate slamming and smashed fingers, these supports automatically pull lids shut when they approach the closed position. Raise the lid until the hold-open mechanism on the support is engaged; slightly lift it again to release the hold and close the lid.

Gradually slow your lid's motion to prevent it from slamming open. To open lids, lower them and the support will slowly and softly do the rest. Manually shut the lids and the supports will hold them in the closed position.

Springs provide lifting assistance to raise and hold lids open—slightly lift the lid to get it started and the support will do the rest. Manually shut the lids and the supports will hold them in the closed position.
