How to Install Roof Railing Bars on a Mercedes A-Class

Model: Mercedes Classe A W176 - Years 2012-2018
Part: Roof rack bars

Let’s see how to install universal roof railing bars on a Mercedes A-Class. Universal roof railing bars are used on vehicles with and without roof rails (fixed bars secured to the roof of the vehicle). Install the bar kit as shown in the video with the bars adjusted to the width of the vehicle. Position the brackets at both ends of the roof; once you adjust the width of the anchoring brackets, tighten the pins with the wing nut (if a lock is present) until they are fully secured to the roof rails of the vehicle. Finally, apply the safety caps on both sides.
