The Grip Handle and L Bracket Kit Pair (Black) from Beneath the Surface is a replacement pair of grip handles and L brackets for an Aquatica underwater photography tray system. The black grip handles are made from a solid piece of aluminum bar for strength and durability and have comfortable rubber grips. The handles have threads at the top for mounting an arm system, in order to enhance your photography experience with accessories such as strobes and lights. The L brackets mount to the grip handles and allow you to attach your Aquatica housing to your tray. This kit pair is part of the Aquatica Tray Conversion Kit, offered separately here for those who do not wish to purchase the entire kit.
