New seatbox help

[Tex577]

Hi there, just bought my first seat box a preston absolute 36. I’ve put it all together and have two of what is pictured in the photo which I have no idea what they are for. There seems to be no obvious place for them to go.
Does anyone know what they are please.

kind regards

tex

They look like adaptors t go on the Preston Innovations space shuttle,
The lower part of your box will sit in the black recess, the arm part of the adaptor will locate on a bracket on the space shuttle.
Don't worry if you don't have a shuttle, the box will fit most barrow systems, such as M.A.P and Frenzee,without the need for the adaptors

Yes this is correct, if you do t need them they are in short supply and worth a few quid on eBay or Facebook.
