I was looking for a pair of helmet locks to put on my bike. I wanted them keyed alike so I only had 1 key for them and not 2. Tried a couple of bike shops and they never had what I wanted and any they had were nearly $50 each. So I had a thought to use sliding window locks instead and mount them on my sissy bar at the lugage rack bolts. It worked and the whole thing cost me $40 for 2 keyed alike locks and bolts to fix them in position.
This is the front on view.
This is the rear view.
This is the view underneath. You can see the pin that holds the buckle.
Thought I would share this with you all.
