International Classification:

US Classification:

294 8212, 24116 R

Abstract:

The invention is a plate with three holes to function as a winch line attachment point and a length and angular adjustment for a chain attached to separated locations on a vehicle. One large hole is used to receive the winch line hook, and two smaller holes with angularly oriented chain locking slots are used to adjust the length of the chain attached to the towed vehicle. The material around the holes is reduced to the minimum size necessary to safely meet the rated towing capacity so that the weight of the plate is minimized.
