The Profoto 1 x 4-Feet Strip Mask creates an even narrower highlight. It has Velcro attachments for fast and easy setup and made with high-quality fabrics. All Profoto Strip Softboxes have a recessed front that allows you to attach a stripmask. It is compatible with the Profoto Softbox Strip and cannot be used with the RFi, OCF, and Clic Softbox ranges. Stripmasks are suitable for more precise lighting control, perfect for creating rim light or highlighting specific areas of your subject.
