Universal frame anchor for fixing substructures and frames

The MFR 10x320mm frame anchor with a conical screw featuring a TX 50 socket is a solution designed for permanent and reliable fixing in construction materials of varying structures—from concrete and brick to aerated concrete blocks or natural stone. Its design allows installation in both new and existing structures, particularly where precision and durability are required.

The 320 mm length makes this anchor ideal for thick walls, substrates, or external constructions requiring greater embedment depth. It is compatible with drills of 7 mm diameter—matching the standard drilling size for this type of element—and its length enables achieving the necessary embedment depth even in the thickest components.

The integrated conical screw with a TX 40 socket (as specified in the manufacturer's documentation) ensures easy and safe installation using a cordless screwdriver. No additional tools or precise alignment are needed—applying the correct torque is sufficient for the screw to "self-draw" and activate the expansion mechanism.

Internal transverse ridges on the anchor surface act like "jaws," ensuring early and uniform expansion within the base material. This means the anchoring effect begins immediately upon insertion, not only after full embedment. The result? Reduced risk of displacement during installation and more stable fixation even under heavy loads.

The flat collar at the top of the anchor prevents galvanic corrosion—particularly important when mounting metal profiles on concrete or brick. The anchor is made from high-quality, aging-resistant nylon, guaranteeing long-term resistance to weather conditions and temperature fluctuations.

All models with a length exceeding 160 mm are supplied as individual components—not pre-assembled. This allows the installer to independently adjust the screw length to match the thickness of the fixed element, providing greater flexibility on-site.

The ETA approval confirms compliance with European standards for concrete and load-bearing masonry—this is not merely a "mounting element" but a tested anchoring system meeting safety requirements for facade structures and door frames.

Why it works

• Two setting depths (50 mm / 70 mm) – allows flexible adaptation to the thickness of the fixed material without changing the anchor.
• Integrated washer (19 mm diameter) – distributes load and protects the material surface from damage.
• Corrosion resistance – both the anchor (nylon) and the screw (galvanized steel) are designed for use in humid environments.
• No need for adhesive or additional components – everything functions mechanically without extra steps.
• Suitable for use in precast reinforced concrete panels – confirmed by the manufacturer as a safe solution for hollow load-bearing panels.

There is no need to seek alternatives. This anchor is already used by installers for mounting windows, doors, facades, and wooden structures—wherever it is essential to ensure that the fixation remains secure even after years of service.
