No more tickets for not wearing a seat belt, and no fishing for seat belt receptacles between seats. With a quick click on each end, buckling up is easy again!

This extender is ideal for Mercedes GL drivers and passengers who can't otherwise buckle their seat belts, which may include some plus-sized people, police, fire fighters, sheriffs, and law enforcement officers with bulky utility belts, passengers in NEMT vehicles, people with mobility impairments and others.

    Belt Extender for Mercedes Benz GL550

    Posted by TwoZero on 11th Nov 2022

    Seat Belt Extender Pros has pretty much become our go to for seat belt extensions for all our vehicles over the years. Even though we don't always need the extra length, we have made it a practice to get at least one each time we acquire another car. They match and hold up exceedingly well. This one for our MB GL550 is no exception.

    This product saved me in having 2 boosters and a carseat in one row in my suv. Plus the customer service was outstanding. I initially order 2 different sizes to figure out which worked best for our car. When needing to return 1 they were quick to reply and i was shocked i didn't have to mail it back. Than I went ahead and ordered the correct one i needed. Nothing saved me like this product.
