Patterns, or gobos, are widely used by designers in theatre, film, photography and television to create atmosphere, project scenery, and generally enhance the visual impact of their lighting.

Conceived by some of the world's leading lighting designers, the Rosco range presently includes hundreds of standard steel gobo designs.

To insure design integrity the patterns are etched using a precise double-sided process on stainless steel. The result is durable, high quality patterns which will withstand the extreme heat at the gate of ellipsoidal spotlights.

Rosco steel gobos are round to allow for rotation in the gate when aligning the projected image.

The standard "B" size is suitable for most fixtures with a 6" lens when used with a Rosco Pattern Holder or the holders of other manufacturers.

Trimming of patterns, where necessary, can be easily accomplished with a pair of scissors.

Q: 2. What size clamp would you recommend for clamping a sound blanket?

A: The size clamp you will need will depend partly onto what item you will be clamping the sound absorption blanket. If you are clamping it to a pipe, you would have to take into consideration the diameter of the pipe, as the jaws have to be wide enough to go around the pipe, as well as to hold the blanket. As a catch-all recommendation, I would typically recommend the Impact 2" Steel Spring A-Clamp (Black), B&H # IMSSCA20B • MFR # SSC-A20B, over the smaller Impact 1" Steel Spring A-Clamp (Black) due to its larger size and extra flexibility.
