1 Rubber Shielding 1 Row 1, column 4 Row 1, column 5 Provides weatherproofing for the U-Bar. It keeps dirt and grime out and prevents scratches. In comparison to the U-Bar it is plush and nice to the touch. Row 1, column 7 Row 1, column 8 Row 1, column 9
2 U-Bar 1 Row 1, column 4 Row 1, column 5 Can be placed around the chosen locking surface and the bike frame. This is then inserted into the base of the U-Lock and secures the bike to the locking surface. Row 1, column 7 Row 1, column 8 Row 1, column 9
3 U-Bar Clamp Attachment 1 Row 1, column 4 Row 1, column 5 Provides nice mating surface for U-Bar and bike frame bracket. Row 1, column 7 Row 1, column 8 Row 1, column 9
4 Frame Attachment Screws and Nuts 4 Row 1, column 4 Row 1, column 5 Screws and nuts used to press clamp edges together around the U-Bar. Row 1, column 7 Row 1, column 8 Row 1, column 9
5 U-Bar Frame Attachment Clasp 1 Row 1, column 4 Row 1, column 5 Nicely holds onto the U-Bar and connects to a base piece that can be attached to a bike frame. Row 1, column 7 Row 1, column 8 Row 1, column 9
6 U-Bar Frame Attachment Locking Tab 1 Row 1, column 4 Row 1, column 5 Tab presses over edge of Clamp attachment on the U-Bar to secure it to the bike frame. Row 1, column 7 Row 1, column 8 Row 1, column 9
7 U-Bar Frame Attachment Spring 1 Row 1, column 4 Row 1, column 5 Spring sits under clasp and provides force on clasp to keep Lock attached to frame attachment. Row 1, column 7 Row 1, column 8 Row 1, column 9
8 Frame Attachment Joining Screw 1 Row 1, column 4 Row 1, column 5 Fastens the two major parts of the frame bracket together Row 1, column 7 Row 1, column 8 Row 1, column 9
9 Frame Bracket Base 1 Row 1, column 4 Row 1, column 5 Holds clasp. Has specific points of rotation so one can change the orientation of the clasp as it connects to the bike. Represents half of the frame bracket clamp. Row 1, column 7 Row 1, column 8 Row 1, column 9
10 Mating Pad 2 Row 1, column 4 Row 1, column 5 Snap in part is smooth and offers a nice mating surface between the clamp and the bike frame (Not Pictured), and the U-Lock and clamp. Row 1, column 7 Row 1, column 8 Row 1, column 9
11 Bike Frame Bracket Clamp 1 Row 1, column 4 Row 1, column 5 Part is placed around bike frame and fastened to the rest of the bracket via screws. Second half of frame bracket clamp. Row 1, column 7 Row 1, column 8 Row 1, column 9
12 Locking Bars 2 Row 1, column 4 Row 1, column 5 Bars fit into notches cut into the U-Bar. When they are in place they secure the U-Bar in place and prevent its removal.

13 Lock Component Housing Cylinder 1 Row 1, column 4 Row 1, column 5 Neatly holds all the parts necessary to actually lock the lock. It has slots cut such that one cannot insert the lock upside down, tracks for the lock bars to slide on, and is designed such that all force imparted to the lock in an attempt to shock it open are directed around the lock bars. Row 1, column 7 Row 1, column 8 Row 1, column 9
14 Lock Housing 1 Row 1, column 4 Row 1, column 5 Housing is made to nicely keep the lock in place inside of the component housing cylinder. It has a tab to prevent incorrect insertion of lock. Row 1, column 7 Row 1, column 8 Row 1, column 9
15 Rubber Grommet 2 Row 1, column 4 Row 1, column 5 Acts as both a seal to prevent dirt or water from entering the lock component housing cylinder, as well as a cushion to protect the cylinder from rubbing directly against the U-Bar Row 1, column 7 Row 1, column 8 Row 1, column 9
