One-hand tear: a hidden magnet gives the roll gentle drag so sheets break cleanly without runaway spinning. Swap rolls in seconds with the quick-release knob. Mount vertically or horizontally using the included screws or optional adhesive screws are advised for lasting hold. The stainless-steel and Abs rail also stores cling film, foil, or hand towels, freeing counter and cabinet space. Rust-proof build backed by a 1-year satisfaction warranty. Weight: 0.58 g (0.00 lb).
