So here’s something you’ve probably seen over and over again and never really considered – the metal loop buck on your car door frame! The little impression on the body of the car where the door latch catches. Just about everyone has bumped against this with their body on the way in or out, if not bumped elbows a few times, and I wonder if you ever asked yourself, what is that thing for?
Most likely you did not – perhaps you think it’s just part of the door latch mechanism, you just didn’t think about it. Which is not completely incorrect but somewhat missing the point, because that little unassuming hook does a lot of work, figuratively and literally.
Like, really, it’s called a door striker technically—sometimes it’s called a latch striker depending on who you ask—and while it looks pretty basic, it does a few important things that you maybe did not know about: some are critical if you want to keep the door literally attached in the event of something terrible.
Let’s break this down.
It Keeps the Door Shut—Especially When It Really Matters
First, the striker is the part that the latch catches when you shut the door and you hear that nice little clunk? That latch is now catching that little metal bar and you are locked in, and it seems pretty simple.
But, this is a serious thing – like obviously you want your car door to stay shut while you drive, no? But more than that, it also plays a role in crash safety! In a crash, that loop is one part of what stops the hinge from getting ripped away and allowing the door to fly open. It helps keep the overall structure of the vehicle more intact, so that the cabin doesn’t crumple like an empty soda can. In other words, it’s just one part of the overall system designed to keep you inside the vehicle instead of getting thrown out of it. So yeah… it’s kind of a big deal.
Also, bonus: it helps keep out wind noise and weather. You close the door, the latch locks it in, and it provides better sealing against wind and rain and whatever horrible noise the tires are making that you’re trying really hard not to hear.
It Prevents Door Rattling Like a Shopping Cart
Even if you aren’t an accident-prone loser (knock on wood), the striker still does its job. The striker is basically what prevents the door from rattling around like a jar with a loose lid when you drive over potholes or dirt roads. The latch catches the striker and holds the door throughout the entirety of the travel, so there is no rattling.
And when the door does not rattle, everything should line up better too, like the weather stripping you have around your window, or all those seals that create your air, noise, and dust barrier. So if your ride is quiet and smooth, you can probably thank that stupid little loop for at least one-fifth of the experience.
People Are Starting to Invent Disturbingly Useful Functions Out of Them
And now it gets even weirder. That striker? It turns out it’s a surprisingly useful anchor point for gadgets and accessories people are putting in their cars nowadays. Picture it as a built-in hook for tools you didn’t even know you needed.
