The accessory pockets are cavities around the perimeter of the main chassis (forward of the axles) which allow all manner of bike racks, tie downs, jetski racks, sides, to be fitted - the list is as long as your imagination and requirements. How many pockets are fitted to the trailer is up to you, and again to your requirements.
At the bottom of this page, there are a couple of options for using the pockets.
The pockets are sliced from the sides of 75 x 50 x 4.0 RHS, drilled and an M12 nut fitted over the hole. Weld onto the chassis where required.
The pocket eyes shown below are great as stand alone tie downs for securing your load to the trailer and perfect for motorcycles.
These can be incorporated into the framework of motorcycle frames, sides or the shroud as per the examples below.
