Gripit Red heavy duty plasterboard fixings support up to 74kg, making them perfect for hanging shelves, shower units, towel rails, heavy curtain rail brackets, bathroom fixtures and speakers. They combine strength with simplicity for an immovable hold. The kit comes with a drill bit and screws. The slim polyacetal wings expand behind the plasterboard, offering a vice-like grip far superior to traditional fixings, which ensures a stable, long-lasting mount. Designed for quick, hassle-free setup and suitable for 9.5mm-15mm plasterboard thickness. Use an 18mm drill bit to install. Simply mark, drill, tap, and twist for a secure fit. Ideal for DIY enthusiasts and professionals alike. Crafted from high-industrial grade polyacetal, these fixings are durable and reusable. Gripit's plasterboard anchors are not intended for damp or damaged walls, nor for objects with continuous, moving, rotating or vibrating motion. Brackets used should be flush against the wall. Not for cantilever/full motion TV brackets. Max weight shown indicates max sheer load (suspended from a fixing, mounted in a vertical wall with a load or weight attached to that fixing and acting vertically downwards) on 15mm plasterboard. Independently tested using 15mm plasterboard.
