This simple little device is a very important component to every standard WDH (Weight Distribution Hitch), and to often it gets neglected until it fails.
The snap-up bracket can become bent, move along the top of the A-frame, or in some case come completely off the A-frame while the TV is in motion.
To minimize any WDH snap-up bracket issues the following tips may be helpful, and are based on the proper mounting and adjustment of the WDH round/trunnion spring bars:
1) Don't use a light duty snap-up bracket for loaded tongue weights
exceeding 1,200lbs. Reese offers a HD bracket #58392.
2) The snap-up bracket should be located along the A-frame such that the
chain hangs vertical with spring bars engaged, and the TV/TT in a straight
line. This will provide for maximum TV turns minimizing the potential of a
binding condition or an unwanted side load on the bracket.
3) The set screw should only be tightened to 1/4 turn (1/2 turn maximum)
after making contact with the frame surface. If tightened to much the
bracket could start to bend when under load, and since most Jayco A-
frames are tube style the side of the tube could be damaged.
4) If the loaded tongue weight exceeds 1,200lbs, Reese recommends bolting
the snap-up bracket to the A-frame. Care should be taken when bolting
the snap-up bracket to the Jayco tube frame. In some cases this can be
accomplished by drilling two clearance holes through the outer surface of
the tube only, and accessing the bolts from "within" the tube frame.
If you elect to drill straight through the tube frame, then a backer plate
should be used on the backside of the tube frame to avoid collapsing the
frame when tightening the bolts. The following pics show my backer
plate on my Jayco tube A-frame:
Hope this helps in keeping your snap-up bracket where it belongs, on your A-frame
