No drilling is required for installation, the strong adhesive sticker fits most smooth flat surfaces including tiles, marble, glass and metal, and will not leave sticky residue or damage your wall. You can finish the whole setup in minutes without extra tools, and it works well in bathroom, kitchen, entryway and other spaces. This mop holder fits most mop and broom poles with diameter ranging from 15mm to 26mm. The built-in silicone rollers increase friction to hold poles firmly in place, you just need to push the pole in to lock it, and pull it out gently when you need to use it. Each holder comes with a small side hook that can hang small cleaning supplies like scrub brushes or cleaning cloths. It makes full use of your vertical wall space to organize your cleaning tools, so your floor area will stay neat and free of messy stacking.
