Using this 4" DELTA 3 Lower Section with T-Base, you can connect an Aquatica DELTA 3 strobe arm with 1" ball mounts to the top of the grip handle on your Aquatica underwater camera housing. The 4" segment requires the #77550 T-style bracket or an equivalent part, which will enable it to mount onto the grip.
Engineered to withstand the elements for many years, this arm component is crafted from an aluminum alloy that's been hard-anodized for exceptional resistance to corrosion. Additionally, it's been treated with Teflon to make it even more durable, ensuring that it will survive the toughest aquatic environments the world has to offer.
