High-quality Fischer DuoTec dowels with screws are designed for installation in various materials: plasterboard, wood and plastic panels. They have a lever mechanism that ensures reliable fixation. The standard hole diameter and low profile allow easy installation in narrow spaces, including insulation cavities. The soft gray nylon surface distributes the load evenly across the panel surface to help minimize damage to the support material. The flexibility of the screw fixing allows the use of various types of 6mm screws and hooks.
