I struggle with keeping caulk silicone tubes organized until I created this organizer. It is hard to find the one you need in a pile of 20 others. You need a special box for them, and it is taking space even if it half empty. I often travel with tubes of caulking and they get beaten up hard in a box. Ones in a while i have to sort them out and throw away the ones that got damaged. So I designed the wall mounted caulk tube holders. They always keep your tube of silicone exactly where you put it. The tube holder has a clip that holds a tube tight even when your trailer or truck is on the move. The tube holder can be installed on a wall, on a cabinet door, or underside of a shelf or ship cabinet0 .! Holder comes in sets of 3 tubes, 2 tubes and 1 tube and can be interconnected to create a row of tubes in any number. Im happy with my holders. Now I can clearly see what colours of caulk I have, how many and they always in good working order. Main colours are White and Black, but if you need any other colours please let me know. For buyers from Europe and Australia especially, regular parcel (which is free) might take up to 12 weeks to arrive, so please choose delivery option that will work for you best. Also you can choose tracking for your convenience. We adding an option for bigger diameter tubes. They could be used to hold paint cans, spray foam cans and larger caulking tubes.
