Can't buckle up in your Mercury Mountaineer? Seat Belt Extender Pros extensions are the highest quality extenders on the market designed to help you fasten your seat belt. Just pick your favorite color and style, and you are ready to drive safely and comfortably again.

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 Mercury Mountaineer 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.

When it comes to safety, quality matters more. Seat Belt Extender Pros offers the highest quality extenders on the market: the best value in the premium category of seat belt extensions. We don't just offer the safest affordable extenders to add extra car seat belt length. With the smooth finish metal surface, the sleek design and available color choices, your extender will also blend in elegantly with your vehicle's interior.

Your safety is our top priority with no compromise. Unlike most belt extensions on the market, Seat Belt Extender Pros extenders are:

  • E4 or E8 Certified
  • manufactured in a US DOT-registered factory that is
  • in compliance with ISO/TS 16949:2009 for Manufacturing of Seat Belt Assembly and Components
  • manufactured to exceed international break strength test requirements for three-point seat belts.

We offer the widest variety of safety tested car seat belt extensions for your Mercury Mountaineer, but we won't let your options get confusing. With industry leading expertise, we can offer step-by-step support to help you find the optimal length and style for your needs. We suggest selecting an extender that adds only the minimum length needed to buckle up.

Extenders are diverse and never universal. Did you know that seat belts are different throughout most Mercury models? Your belt's metal tongue and receptacle shape depend on the seat itself and the manufacturing year of your Mercury. Seat Belt Extender Pros has the expertise to make your search easy.

Our regular extender style is made out of woven seat belt webbing material just like the seat belts in your car. Rigid extenders stand upright.

Seat Belt Extender Pros is known for industry-leading expertise, the widest selection of extenders available, an uncompromising focus on quality, and boundless devotion to customer happiness. With a decade of experience as the category pioneer, we're always on the cutting edge of new safety and convenience features. Recognized as the #1 seat belt extension brand worldwide with an extensive knowledge base, we are here to help you wear your seat belt comfortably again.

This product is for those who otherwise can’t buckle up. The seat belt extender’s metal tongue should click into the receptacle of the vehicle’s seat belt and the seat belt’s metal tongue should click into the receptacle of the seat belt extender. However, read and abide by your car manufacturer’s owner’s manual prior to installation or use of this product, which may not be compatible with your car. Failure to read and abide by manufacturer’s warning regarding purchase, use and installation could result in serious injury. Adults and children who can use the existing seat belt should not use an extender. Such unnecessary use, including with child restraints, could result in serious personal injury or death in the event of an accident.

    Wonderful deal. Solved a problem with a snap (pardon the pun). Robust, attractive product. Easy to switch from seat to seat.

    Seat Belt Extenders

    Posted by Duane on 11th Apr 2018

    I had a hard time finding extenders for my 2006 Mercury Mountaineer. I ordered 2 and they shipped right away. They fit perfectly and do exactly what I wanted. Fast shipping, product as advertised and it works great. Thank you!

    Mother-in-Law loves me now

    Mom had a very difficult time latching the seat belt in the back seat. This extender raises the latch, up off the seat where she can find and hook it so much easier.

    Belt Extenders

    Posted by Unknown on 25th May 2017

    I have ordered two different belt extenders and I was very happy with the product and service. The extensions look like original equipment and fit perfectly. I received the extenders quickly and timely for use.

    Product good, service not so great

    Posted by Unknown on 22nd Aug 2016

    The product is quality and works well, but the service through this company was not stellar. I ordered the extender in the beginning of July. Two weeks later it still had not arrived, so I contacted the company who said they weren't sure which extender to send me and asked me to send photos of the seatbelt in my car, which I immediately did. I got an email the next day saying my order was shipping, but I never received an email with tracking info so another 10 days after that I contacted the company again only to be told that my order was still in limbo and they needed pictures of my seatbelt (which I had already sent!). I sent them again but told them how disappointed as it was now going on a month of not getting my order. Had I not reached out to them in the first place I'm not sure I ever would have gotten it!
