ok, here's the final product! Boxes and hangers to go on a Cyclerack.
Boxes measure 8x18x14 tall. Complete kit weighs in at 24lbs.
All nuts and bolts are stainless, except the handknobs. No tools needed to install or remove!
Latches have a safety catch feature.
Lids have rubber gaskets to keep the dust and water out.
As pictured, they are mounted as low and as far forward as possible. This was done to install to a TW with no modifications.
If you are willing to modify your rear turn signals, the boxes can be moved about 8inches rearward, depending on how YOU mount the hoops to the boxes.
The hoops are drilled, the boxes are not. This allows YOU to put them where you want them, to fit your gear and preference.
