The Westcott 45" White Satin Umbrella with Removable Black Cover is a great portable way to really soften or reflect light from a flash or strobe. With the cover in place, easily bounce light. Remove the cover for instant diffusion. For any on-location photographer, umbrellas are a great choice as they set up and tear down in seconds. Now featuring fiberglass framework, this umbrella's durable construction provides flexibility and strength without excessive weight. The shaft is finished off with a 7mm tapered tip allowing for use in conjunction with many European and specialty lights on the market. Some of these lights have a 7mm catch pin making them difficult to find modifiers that will work with them correctly. Our catch pin insures a perfect fit with almost all of the most popular lights. Rib tips are constructed of all metal and are finished with an 8-count thread pass providing quality construction and product durability.
