GT17 Type 1 vented broad brim hard hat, earmuff suitable

The GT17 is a broad brim hard hat built for full-day wear on Australian sites. The name is a mouthful, but the short version is simple: it is a lightweight vented shell with a broad brim, a padded ratchet harness, and a 30mm slot designed to take clip-on earmuffs and other accessories. That last point matters if you already run slot-mount hearing protection and want a hat that works with it rather than against it.

It is designed and made in Australia, which is worth noting for buyers who care about local supply. The internal fit is handled by a fabric six point adjustable height harness with a crown strap spreader, and the rear ratchet is padded and nape adjustable so you can dial it in without it digging into the back of your head. A metal lamp bracket on the front holds most headlamps, so it suits low-light and underground work as well as general site use.

If you want the full spec or you are ready to order, you can view the GT17 hard hat on Done Right Safety and check the listing for the standards and rating details before you commit.

A hard hat only does its job if it fits properly and you actually keep it on, so most of the decision comes down to fit, compatibility and what you are mounting on it.

Picking the right setup

Start with the accessories you already run. The 30mm slot is the universal size that takes most clip-on earmuffs, face shields and visor brackets, and the listing notes it suits Force360 PPE, so if your hearing protection is slot-mount you are likely covered. If you work in poor light, the metal lamp bracket is the feature to look at, since it is built to hold most headlamps rather than relying on an elastic strap. For branded crews, the five colour, four position printing means you can run a fleet in house livery.

Getting the fit right

Set the six point internal harness for height first so the shell sits at the correct distance from your scalp, then use the padded rear ratchet to draw it in. The nape adjustment lets you control how snug it sits at the back of the head, which is what stops it tipping forward when you look down. A broad brim shifts a little weight forward, so take a moment to balance the ratchet tension rather than over-tightening one side.

Inspection and replacement

Treat it like any hard hat. Check the shell for cracks, gouges or sun damage before each shift, and look over the harness webbing and the ratchet for wear or fraying. Replace the hat after any solid impact even if you cannot see damage, and follow the manufacturer guidance on service life. For the specific standard, rating and replacement interval, check the product page or datasheet on Done Right Safety, since those details are not listed in this guide.

An honest note up front: Done Right Safety does not list another broad brim hard hat alongside this one, so the products below are adjacent PPE options from the same head and body protection range rather than like-for-like hard hat alternatives. The comparison is here to show where the GT17 sits, not to pretend a respirator or a coverall does the same job.

The choice here is really about which hazard you are controlling. The GT17 is the pick when head impact and sun exposure are the issue and you want a shell that takes slot-mount earmuffs and a headlamp. The JSP Typhoon 8 covers your airways and is the only item in this group with a listed standard, AS/NZS 1716, so it belongs in the conversation when dust or fumes are present. The two coveralls deal with body contamination, with the Force360 ChemRepel HV adding hi-vis and a chemical barrier.

On a lot of jobs you will run more than one of these together, since the respirator is built to sit behind a visor and the Barriertech hood is shaped to fit over a respirator. The GT17 is the head protection layer that the rest of the kit hangs off.

What is confirmed on the listing reads well for full-day site use. The GT17 is an ultra light Australian made shell with a genuinely adjustable fit: a six point internal harness, a crown strap spreader and a padded nape ratchet. The broad brim and front lamp bracket make it sensible for outdoor and low-light work, and the 30mm slot keeps it compatible with common clip-on hearing protection and other accessories, including Force360 PPE.

The plastic free, recyclable packaging is a small but real plus for buyers tracking waste on site, and the five colour, four position printing makes it a fair option for branded fleets.

What you should verify before ordering: the certification and rating. This guide does not list a standard for the hat, and the brim style and any earmuff attenuation figures should be read straight off the product page or datasheet on Done Right Safety rather than assumed from the name. If a specific standard is a procurement requirement on your site, confirm it on the listing first.
