1/4" x 1" Aluminum Frame (one piece) with 5/8" Welded Aluminum Pin.
These flat stock gel frames make it easy to tape gel or diffusion onto. Want to create a nice soft, shadowless light? Use a piece of Rosco or Lee 216 White Diffusion on one of these. Place it on a grip stand about 18" from your light and you are ready to go. Using a really hot par light with a narrow lens? Sometimes they will burn thru almost any gel if mounted on the barndoors. Just add your gel to a gel frame and mount it on a grip stand out in front of the light... problem solved.
