I think hes on about the ones with screwdriver slot in, you can then turn lockshield off, close screwdriver slot and remove the rad full of water for decorating,
I have not used them but they will leak they look cheap and nasty,
Its just as easy to thump the end of the rad or cap it before removing and u can flush it out while its off so they are pointless really.
DIY product i dont think pros would use them
