A pair of latches lock the windshield down until the spring loaded "trigger locks" are intentionally disengaged, allowing the rider to remove the windshield. Kits are available in a combination of CNC-machined aluminum plates, stainless steel bolts and aluminum anchors, or black E-coated plates, bolts and anchors.
Once I got the bracket attached correctly, it slides in and off easily. I have an old Road King so you have to make sure it is lined up properly but it works great.
