When building a MOC I realised there is a material difference in the performance
of the two variants of the bar holder with clip (Part Nos 11090 and 44873) and
think this should be highlighted in the Bricklink catalogue listings.
44873 has a deeper socket than 11090 and the overall length when they are combined
with a short bar is not the same - see attached photo. 11090 has a small hole
on the body, 44873 on the clip.
