FISCHER DuoHM 4x55 S TX Cavity Wall Plug | High-Performance Metal Fixing for PlasterboardAchieve unparalleled stability and holding power in all your cavity wall installations with the FISCHER DuoHM 4x55 S TX, the professional´s choice for secure mounting in board building materials. Engineered for reliability, this premium metal wall plug is specifically designed to overcome the challenges of fixing heavy items to hollow surfaces such as plasterboard, gypsum fibreboard, and wood-based panels. Whether you are a professional tradesperson or a dedicated DIY enthusiast, the DuoHM provides a robust and permanent anchoring point for a flawless and durable finish.Exceptional Load-Bearing CapacityThe core strength of the FISCHER DuoHM lies in its intelligent design. During installation, its expanding arms spread out behind the panel, distributing the load over a large surface area. This mechanism creates a powerful and secure hold, allowing you to confidently hang heavy objects like kitchen cabinets, television brackets, shelving units, and large picture frames without fear of failure. Its robust metal construction ensures it can handle significant tensile and shear forces, providing a fixing you can trust for critical applications. This superior anchoring technology makes it an ideal solution for modern stud wall constructions, providing a dependable fixing point in the hollow spaces between the studs.Effortless and Secure InstallationExperience a frustration-free installation process from start to finish. The DuoHM features sharp, integrated anti-rotation locks—prominent claws on the plug´s rim—that dig into the plasterboard as the screw is tightened. This crucial feature prevents the entire plug from spinning in the drill hole, a common issue with inferior cavity fixings. The pre-assembled screw with a TX (TORX) drive ensures optimal torque transmission, reducing the risk of cam-out and allowing for a controlled, powerful tightening action with a standard cordless screwdriver or by hand. For serial installations, the plug is also perfectly compatible with assembly pliers for even faster setting.Ultimate Flexibility and VersatilityThe FISCHER DuoHM 4x55 S TX is designed for ultimate convenience. Its internal metric thread is a key feature that allows the included screw to be removed and re-inserted multiple times. This is perfect for situations where you might need to take down an item for decorating, maintenance, or relocation without compromising the integrity of the fixing in the wall. This reusability makes it a practical and economical choice for both permanent and semi-permanent fixtures. Its suitability for a wide range of panel thicknesses adds to its versatility, making it a go-to component in your hardware collection.Main Features:* Expanding Arm Technology: Arms spread behind the board to create a large, stable bearing surface for maximum load capacity.* Integrated Anti-Rotation Locks: Claws on the rim embed into the panel material to prevent the plug from spinning during installation.* Metric Internal Thread: Allows for the repeated removal and re-fastening of the object, offering superior flexibility.* Optimised Screw Drive: Comes with a matching screw featuring a TX drive for excellent power transfer and a secure fit.* Pre-Positioned Installation: Designed for a simple and straightforward installation process in pre-drilled holes.---Technical Specifications:* Anchor Type: Cavity Metal Fixing* Model: FISCHER DuoHM 4x55 S TX* Drill Hole Diameter (d₀): 8 mm* Panel Thickness (dp): 7 - 21 mm* Anchor Length (l): 55 mm* Minimum Drill Hole Depth (h₁): 60 mm* Screw Dimensions: M4x61 mm* Screw Drive: TX20. tradeinn Bricoinn
