WHY YOU NEED IT

When the door will not open.

Four times a side window is the only way out, or in.

Four times a side window is the way out: Water, Car fire, Crash, Dog or child
Water: hand reaching for a Safety Hammer mounted beside a car side window, water outside

Water

Your best chance to get out is the first minute, while the car still floats.

University of Manitoba, Giesbrecht, 2016.

Belt off, press the tip to a side window, get out before the water reaches the window.

Car fire: hand holding a Safety Hammer beside a burning car

Car fire

Electronic doors may not work in a fire.

US Fire Administration; Rappsilber et al., Fire Safety Journal, 2026.

No power needed. A firm press breaks a tempered side window.

Post-crash entrapment: hand holding a Safety Hammer at a cracked car side window

Post-crash entrapment

In a UK study, 11% of seriously injured crash patients were trapped in the car.

Nutbeam et al., 2021.

The blade cuts a belt that will not release. The tip opens a tempered side window.

Dog or child trapped: hand holding a Safety Hammer in a car with a child seat

Dog or child trapped

A parked car heats up fast. In the US, an average of 37 children a year die of heatstroke after being left in a hot car.

National Safety Council, Injury Facts.

From outside, a firm press on a tempered side window. Keep one in your bag as well as the car.

HOW THE SPRING WORKS

Push. Load. Strike.

01

Contact

The breaker end meets the glass.

02

Load

The spring compresses.

03

Release

The striker fires into one point.

HOW TO USE IT

  1. Pull it from the holder. It sits within reach of the driver seat.
  2. Press the tip into a corner of a side window. Keep pushing.
  3. The spring fires and the glass shatters. Push the glass out.
  4. Belt stuck? Hook it into the fork at the other end and pull.

Why not just use the headrest?

A FAIR QUESTION
A headrest can't break a car window.
Some headrests don't come off.
The post needs a swing you don't have room for. The spring needs one press, from your seat.
COMPATIBILITY CHECK
Will it work on your car?
Use the guide below to check whether it will work on your car. Legend: Tempered / Laminated / Check the label.
Check the small print on your glass for 'Tempered' or 'Laminated'. Glass differs by trim, year, market and replacement glass.
BEFORE YOU NEED IT
Test it yourself.
Every Hammer comes with a piece of tempered glass, so you can test it at home before you need it.
01 Open the box โ€” Safety Hammer, car mount, practice glass, quick guide.
02 Follow the quick guide.
03 Now you know the feel โ€” the spring resets, mount it beside your seat.
Optional 3-pack of extra practice glass is available as an add-on on the product section above.
GUARANTEE
30-day money-back guarantee โ€” If you don't like it, send it back within 30 days of delivery and get your money back. Even if you tried it.
Less than 1% of our customers return it.

Stephanie Lois Koch

12w

I ordered several of these tools and tried one today at an auto wreckers. The window breaker shattered the rear window of a smashed up car they had in the rear lot. The guy who I spoke to there was amazed that it worked! Does the window breaker work as effectively on tinted windows of a vehicle too?

I've been a firefighter for 30 years and we had these in the fire academy. They have been around for decades. Called a center punch. Cool story though.

FAQ

Which windows can I use it on?

Tempered side windows, the type most cars use for the door windows. Not windshields, and not laminated glass. Use the compatibility checker above as a guide.

Can I practice with it, and what is included?

Yes. Every box has the Safety Hammer, the car mount, practice glass and a quick guide. Break the practice glass to test it before you need it.

Can I use it more than once?

Yes. The spring resets after each press, so if the first press does not break the glass, press again.

How many do I need?

Start with one per vehicle, mounted where the driver reaches it without looking.

Is this a subscription?

No. One-time purchase. No subscription.

Do I need a discount code?

No. The bundle price applies automatically in the cart. No code needed.

When will it arrive?

Ships next day. Delivered in 3 to 7 business days.

Where should I mount it?

Beside the driver's seat, where your hand reaches without looking: the console side, the door pocket, or the mount provided.

How do returns work?

Contact us within 30 days of receiving your order, even if you have tried it. You get a return label and instructions, and a refund to your original payment method. See the full refund policy for details.

Keep it within reach. Hope you never use it.
