### Product Overview The PVC Frame Fixing SXR 10x180 (Pack of 50) is a premier long-shaft frame fixing engineered by Fischer, designed to deliver exceptional fastening versatility and structural security across the entire spectrum of solid and hollow building materials. Combining an advanced high-performance nylon anchor plug with a matched, high-tensile zinc-plated safety screw, this fixing with precise dimensional metrics of 10x180 is supplied in an economical pack of 50 pieces. Whether working with dense reinforced concrete or fragile perforated brickwork, the Fischer SXR series stands out as the ultimate universal anchoring solution for window and door frame installations, timber substructures, and heavy architectural fittings. ### Key Engineering Features & Advantages * **Universal Substrate Adaptability:** Engineered with a dynamic expansion geometry that expands solidly against dense concrete and solid masonry, while forming secure mechanical interlocks (knotting) within the cavities of hollow and perforated bricks. * **Low Installation Torque:** The optimized friction-reduction ribs and plug profile allow the safety screw to be driven in with minimal effort, reducing installer fatigue and extending power tool battery life. * **Integrated Anti-Rotation Lugs:** Prominent locking wings located near the plug collar prevent the nylon sleeve from spinning inside the drill hole during screw penetration, ensuring a foolproof installation. * **Thermal & Electrical Isolation:** The premium nylon sleeve prevents direct metal-to-material contact, effectively eliminating thermal bridging and mitigating galvanic corrosion risks in metallic window frames. * **High Pull-Out Resistance:** The extended shaft length ensures deep embedment into the base material, bridging non-load-bearing plaster and render layers to anchor securely in the structural wall. ### Technical Specifications & Material Properties The anchor plug is precision-molded from virgin Polyamide 6 (PA6) high-grade nylon, a material renowned for its exceptional toughness, resistance to aging, and stability across extreme temperatures (-40°C to +80°C). Unlike cheap plastics, Fischer nylon absorbs vibrational energy without becoming brittle or cracking over time. The accompanying safety screw is manufactured from hardened carbon steel with a protective zinc-plated (ZP) finish, featuring a countersunk or hexagonal head designed to sit flush against the fixture. The dimension metrics 10x180 specify the anchor diameter and total length, tailored for specific fixture thicknesses. ### Application Areas & Use Cases The outstanding reliability and multi-material certification of the PVC Frame Fixing SXR 10x180 (Pack of 50) make it an essential fastening choice for carpentry, facade construction, and interior fitting: * **Window & Door Installations:** Structurally anchoring timber, aluminum, and UPVC window frames and external door sets into surrounding masonry openings. * **Timber & Metal Substructures:** Fastening squared timbers, wall plates, and metal furring channels for interior drywall constructions and external timber cladding. * **Kitchen & Interior Fixtures:** Mounting heavy wall-hung kitchen cabinets, wardrobes, bookshelves, and large flat-screen television brackets to hollow brick or aerated concrete walls. * **Architectural Facades & Sunshades:** Securing bracketry for exterior facade panels, awnings, canopies, and solar shading systems. * **Handrails & Balustrades:** Fixing internal stair handrails, guardrails, and wall-mounted safety grab bars in residential and commercial buildings. ### Installation Guide & Best Practices For secure, long-lasting fastenings across diverse building substrates, adhere to the following installation instructions: 1. **Drilling:** Using a masonry drill bit corresponding to the anchor diameter (10mm for SXR 10 series), drill a hole through the fixture into the base material. For perforated or hollow bricks, use rotary drilling mode without hammer impact to avoid shattering the internal masonry web. 2. **Hole Cleaning:** Remove drilling dust from the borehole by blowing it out or vacuuming. Clean holes ensure that the nylon plug achieves full surface contact with the substrate. 3. **Push-Through Insertion:** Push the complete SXR frame fixing (nylon plug with pre-assembled screw) through the mounting fixture into the drill hole until the plug collar sits flush against the fixture. 4. **Driving the Screw:** Using an appropriate screwdriver bit or socket wrench, drive the safety screw into the nylon plug. As the screw advances, it expands the nylon sleeve radially in solid materials or causes it to fold and lock securely around the webs of hollow building blocks, completing a robust installation.
