Replacement cable grommet on my interior door, 1/2" cable. Went through two tubes that must have come from an old warehouse. I couldn't get the cement out of the first tube unless it was in a vise. The nozzle on the second pipe was clogged, then it jerked out. I finally had enough drain cover to start laying the rope seal. fell off immediately. Back to the liquid, which isn't much better either: you'd think by 2018 someone would invent a product that would easily do the job.
