Brought the safe n sound hook extention 300mm for our car seat to fit rear facing in a 2017 Nissan Pathfinder. It works great and was delivered very quickly after being ordered online.

This is an important accessory that we needed to properly fit our car seat into our Nissan Patrol. It is a must have for bigger cars that do not have isotap buckles and was available at a reasonable price and delivered with efficiency in time for the birth of our baby.

Easy to use and perfect for my suv go give extra length to car seat
Exactly what we needed for our baby capsule strap to reach the bolt in the back of our little Holden Astra hatchback!
Easy to use. Just what we needednto.ensure the car seat was secure
Anchor length should have been big enough in the car seat itself. I found this expense unnecessary.
Great product, simple, efficient and affordable, needed extra length for a capsule and booster seat in a 7seater 4wd
I got home and installed my new $600 car seat only to learn that it doesn't come with all the parts I need...I live a half an hour away from the shop and have a baby. It took me ages to the time to get to baby bunting...and now I have to go back for a silly little cord. The salesperson knew what car we had and didn't mention needing this. Very frustrated.

This extension strap is suitable for child restraints manufactured from march 1993 onwards. Some vehicles require an extension strap to allow a tether Strap or upper anchorage strap on a child restraint to be connected to the child restraint anchorage in the vehicle. This is most often required for seat in the rearward facing position. The 300mm is the most commonly required extension length in our experience. This extension strap will work with all Britax seats as well as other brands.
