Selection and use
Initial fitting replaces one wheel bolt with the appropriate special bolt and sets the distance using the adjustment bolt. The standard locking bar is 20 mm in diameter. Some rim/brake combinations require a separate 16 mm bar, so wheel size alone does not establish fitment. The manufacturer excludes motorhomes and vans. A storage case and two keys are included.
