The SR-SHOE-D Speed Ring for Dual Shoe Mount Flashes from Impact is a portable, highly mobile accessory that allows you to double your flash power while creating flattering, soft lighting with equipment that you already own.
SR-SHOE-D has multiple benefits and convenience features aimed at making it an effective light shaping tool as well as a pleasure to use. Its four shoe mounts, allow use of 2 flash units along with separate radio receivers. The 360-degree rotating aluminum ring is labeled for easy installation of extra small to medium sized rectangular, square, strip, or octagonal softboxes. You can use 1 flash or add a second flash to double your power. If the power of the single flash is sufficient but you want faster recycling, set them both to 1/2 power and use the second flash as a "booster" to halve your recycling time. Dual brackets let you manipulate the angles and depth of the speedlights within the softbox to adjust the light spread.
Lastly, the sturdy unit has a 5/8" receiver for industry-standard light stands and tilting adjustment is made possible via the ratcheting-locking tilting handle.
