Blue Block Out & Split Liner Tape™ Spend less time on clean up and more time making money These solvent-resistant polyethylene block out tapes, Blue Block Out for wood frames, or Split Liner tape for metal and retentionable frames, keep ink from getting between the frame and mesh. You spend less time on clean-up, because they peel off cleanly from the mesh without leaving adhesive residue. By taping a frame with Split Liner, you can retension a screen without having to remove and reapply the block out tape.
