Give yourself some slack - with the Seat Belt Adjuster!

This easy-to-use seat belt adjuster allows you to control the tension of your seat belt and can be adjusted to fit any individual. This useful device moves the seat belt off of your neck to end irritation, chafing and discomfort. It can even prevent clothing from wrinkling under the seat belt.

The Seat Belt Tension Adjuster works by attaching to the top of your seat belt by creating slack without compromising safety.

The Seat Belt Tension Adjuster comes in packs of two so you'll have one for the driver and passenger or an extra for a second vehicle.


After buckling your seat belt:

1. Separate the top of the adjuster from the bottom by holding both pieces and sliding them in opposite directions.
2. Position the Seat Belt Tension Adjuster on your seat belt strap where it retracts, with the red lock and flap facing you. Snap the top and bottom back together with the seat belt in between.
3. Slide adjuster towards the seat belt retractor, and pull the strap not more than one inch out, allowing only enough slack for your comfort.
4. Lock into position by sliding the red tab to the right. Unlock by sliding the red tab to the left or to re-adjust.

    Great device

    These seat belt adjusters are wonderful and easy to use. They make using a seatbelt much more comfortable for those of us who are tired of having it hit our necks. I like the fact that it can be adjusted for anyone of any size or height.

    These extenders are easy to install and remove. They work perfectly for keeping the pressure of the seat belt off your chest. I highly recommend this product.

    Good job in keeping a car shoulder strap from cramping your shoulder and simultaneously keeps you safely in car seat. After a week in use seat belt start to slip through tension clamp adjuster and must be readjusted.

    Seat belt saver

    I love these. They keep the belt loos enough so you don't feel choked and restricted. And the do not slip down the belt once placed where you want them.

    Love this!

    I'm short, so the driver's side seatbelt always chokes me and rubs my neck... to the point where I had a bad skin issue. I've tried LOTS of products like this and this one is by far the best! It does wear out after a while, but it lasts a very long time before the tension bar stops working.

    I bought my first set 17 years ago after breast cancer, chemo and 11 surgeries. I am short and the seat belt hurt. My daughter-in-law just went throught breast cancer and I bought her a set. She loves them for the same reason.

    I have used an adjuster just like this one for years, but it recently broke. I was very happy to find a replacement just like the one I had.
