Barrel-disc 20L 279.5/173/5

Drum disc for 20-litre pails with liner. The disc is placed on the liner inside the container and the film is cut out cleanly along the inner diameter. It prevents the liner from being pushed past the follower plate seal when the follower plate is lowered and protects the seal for longer service life. Outer diameter 279.5 mm, inner diameter 173 mm, thickness 5 mm.
