Been asked to look into recommending parking bollards but know little about them.

Need to be lockable and hinged, so when padlokck is removed they fold down flat without the base coming away.

Also think that the ones that are concreted in vs bolt on are better i.e. stronger and harder to remove.

Budvey, dunno, 50 quidish.

we sell them at work
