Ball or Roller catch?

"Bales catch".

If the OP can do similar, what I did was to screw a strip of
varnished MDF to the top of the panel, which hooked under the
lip of the bath, when the whole panel is lifted up. When the
panel is lifted, a strip of timber with some quadrant glued
to it is slipped under, and screwed to the floor:

To remove the panel, just undo the screws which hold the quadrant
and stripwood to the floor, pull out the quadrant/stripwood, then
the panel simply drops and can be removed.
