SCCs SecureBar is the easiest, strongest and most versatile load lock ever made for cars, SUVs and trucks. With an adjustment range of 48"-78", the SecureBar is short enough to control a load of groceries in the trunk of your car, and long enough to span a 6 foot pickup bed, lengthwise. Its square steel tubing is much stronger than other pickup bars, and its soft rubber feet easily adapt to irregular surfaces with no risk of damage to paint or other finishes. No plastic parts here! The all metal locking handle and thumb release along with a positive rack-and-pinion operation provides a smooth operation.
