W-UR 14 F SymCon® plastic frame fixing with zinc plated steel hexagon head bolt, flat collar and SymCon thread

Reliable and quick

• Reliable follow-up expansion capability due to ingenious anchor geometry


• The teeth expand in four directions and claw into the base material


• Anchorage via friction locking between anchor sleeve and base material


• High loads due to expansion in four directions


• Improved load transmission through even, continuous load transfer across the entire expansion area


• Virtually no spinning of the anchor sleeve due to low installation torque and expansion


• Anchor sleeve made of high-quality polyamide


• Very strong anti-rotation lock


• Does not require an additional U-washer and prevents contact corrosion

Intuitive installation

• Time savings due to immediate load-bearing capacity


• Minimal installation work because the anchor sleeve and special screw are pre-assembled


• Hammer-in stop prevents premature expansion of the anchor during installation

Multiple embedment depths

• Masonry: Two embedment depths (50 and 70 mm)


• Concrete: Three embedment depths (40, 50 and 70 mm)
