Top quality set of 8 floor runner end caps, made by CASA Lambretta in Italy.
 
These have a tube on the underneath of 6 of the end caps that you do not get on the cheaper versions, this stops you breaking them when you tighten them down, you do not need this with the 2 that fit with the T nuts.
 
These are ribbed GP type and come with all the fixings - bolts, nuts, washers and now including the T nuts.
