I tried using my own springs with cut-outs of take-away containers for years. These are SOOooo much better! Undo (and do up!) the hinge clamps without needing to hold onto the hinge bracket. Brilliant!

These clamp plates are compatible with the regular Brompton bolt and improve the process of locking and unlocking the two frame hinges. They don't float loose like the regular plates do. Recommended.
