Screen Paint Supply Velvet Projector Screen Boarder Tape 

• 2” or 3” wide black velvet tape that absorbs 100% of any light that spills over the edge of the screen.
• It remains jet black to give the screen a crisp high contrast look. Other brands are just black felt tape and show a ghost image spilling onto the tape.
• Easy to apply self-adhesive tape.  Joints in the tape don’t show because the black fibers hang over the side enough to cover any joint in the tape.
• The tape comes in 36’ and 72’ rolls.
