Already a legend in Asia, Kupo has introduced a line of high quality grip gear aimed at videographers, broadcast professionals and photographers everywhere. Durability, exacting standards of manufacturing and dependability are hallmarks of the Kupo name. This Kupo Off-Camera Flash Alli Clamp is a great way to lighten your load while utilizing your on-camera flash (or a few of them) to light your subject. The Alli Clamp is just the ticket for on-the-go photographers to take advantage of the off-camera TTL capabilities of their camera systems to create mini kits of these lightweight flashes. The clamp has a jaw that can clamp onto items up to 1.57" thick. Rubber nubs on the inside of the clamp prevent damage to paint or furniture. The clamp has a 5/8" receiver for lightstands or a 5/8" stud for gripware like super clamps with matching receivers. The Alli Clamp is topped with a metal locking shoe mounted to a rotating ball for your flash.
