A) Mounting Brackets
These mounting brackets make it quick and easy to attach accessories to your helmet.

B) Fiberglass and Carbon Fiber Reinforced Shell.
Kirby Morgan^® has over 50 years experience in composite laminations. The helmet shell is hand laid up glass fiber reinforced thermal setting polyester (fiberglass) with carbon fiber reinforcement at key points for added durability. It is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor.

C) Defogging Steady Flow Valve
provides an additional flow of gas into the helmet for ventilation and defogging.

D) Emergency (EGS) Valve
supplies backup breathing gas to the diver.

E) Gas Supply Non-Return Valve
is Commercial Rated™. It prevents loss of gas pressure in the event of umbilical damage.

F) Side Block
Multi use side block has additional ports built in to provide controlled air flow, if needed.

G) Whisker Wings
Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

H) Pull Strap
The strap has been improved with the addition of a stainless steel “D” ring. This makes for easier removal. It also allows the assembly to easily be hung for drying.

I) Positive-Lock™ Latch System
This latching system, developed by Kirby Morgan^® in 1992, consists of two sealed Positive-Lock™ pull pins which are pulled forward to release the neck collar and neck dam locking system. Even when the latches are released, the O-ring sealed neck dam maintains a positive seal and will not allow the seal to be broken until the collar actually clears the diver’s shoulders, thus helping to prevent any flooding of the helmet.

J) Front Yoke
The front yoke serves as the retaining device at the front of the neck ring assembly (instead of a chin strap).

K) Head Cushion
The Head Cushion gives the helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.

L) Adjustable Neck Pad
The helmet attached yoke system has an adjustable neck pad which is made from a scuff resistant elastomer. In conjunction with the spring activated front neck dam ring lock, it provides protection for the bottom of the Helmet.

M) Quad-Valve™Exhaust System
Makes the helmet very dry with no loss of breathing performance.

N) Communications are either bare wire posts or a waterproof connector.

O) SuperFlow^® 350
This all metal, fully adjustable, Commercial Rated™ demand regulator provides easy breathing and excellent performance with low pressure compressors.

P) Nose Block Device allows the diver to block the nose to equalize ears.

Q) Silicone Oral Nasal Mask is made of a superior silicone material which is hypo-allergenic and has a longer work life than latex. It also provides an attachment area for the prescription lens frame, kit part number 525-775 with oral nasal and 525-776 without oral nasal.

R) Air Train diffuses the incoming breathing air/gas onto the face plate to defog the lens.
