Hello, you will have to contact the company. They are very nice. The one I tried didn't fit my needs, so suggest being quite specific.

As long as you have a b&w hitch system in your truck the extender will work, it works great in my truck, gives me a couple extra inches when pulling my travel trailer

If you don't over-inflate and simply place a throw or blanket over the extender then you shouldn't have any problem. I use mine with two 70lb greyhounds and have zero issues.

These seat belts extenders are two different sizes. Extender a and Extender b, one of the extenders will fit. That's why I purchased this set. One fits my Chevy Malibu and one doesn't. Either way it is a win/win situation... :-)

I have a Britax Boulevard 70 and it did not fit, it was too short for the high back. I'm not sure about the Marathon.

If you read the descriptions at the bottom there's a section highlighted in blue titled "more product information". Click on that and there's a heading called "Choosing an extender yourself". Follow those instruction. You have to measure the width of the metal tab. There are different sizes. If it is not 1", then go to the company website and find one that matches your car. I put mine in a 2000 Isuzu Amigo and it fit perfectly. Also on the company website are phone numbers if you would like help in choosing the correct size. Good luck!

Mine is set at 36.5" with the extender. The extender makes it basically so I didn't have to unscrew it at all, 1/2" on each side. It may work, I would go buy one at the store (walmart) and make sure it will fit. Then, if it doesn't work returning it will be easier. I think it will probably work though.

You need to measure the width of the tongue on the male end of the seat belt that you intend to use the extender on. If the tongue is 1" wide, you will need type "B". If it is only 7/8" wide, you will need type "A". It is possible for a manufacturer to have installed different seat belts within the same vehicle. I have a 2008 Hyundai Tucson and the extender works just fine to allow access to the buckle with 3 car seats installed.

It should. I have 2. One on a Britax Marathon 70 and another on a Britax Advocate 70. Fine on both of those. Hope that helps :)

I also bought the Uppa Baby tray and it fits. It's a much better tray than the Britax.

I'm not sure. But measure the width of the insert and check the shape of the hole in the insert. The Extender spec. sheet will give you the size to compare with your measurements.

There are only two different size belt extenders that I could find. The measurement is the width of the square, metal piece that fits into the clasp on your vehicle's belt. Go measure the metal fastener on your vehicle. Order the same size. It seems safe to me and I have been pleased with it. (Maybe a bit expensive but no more so than the one from the car manufacturer.)

not sure, you need to go on the sight to find out about size, the belt also comes with an extender.

I own a 2002 F 250 Power Stroke Diesel with Crew Cab. My extender is 18.25 inches high at the tallest point. When you order these extenders you are ask for the year, make and model of the vehicle. They match up the extender for you.

Hi Cynthia, The extender won't help you. It's for DSLR cameras. What you need is a Celestron 93626 universal adapter. If you wish to see how these work, look up "Digi-scoping" on YouTube. Hope this helps.

Make sure you're in the designated range of focal lengths the extender is designed for. Otherwise, email the makers.
