EJOT® ejotherm® STR U 2G

Applications

• Universal screw-in anchor for countersunk and surface fixed installation in concrete and masonry
• For all substrates (A, B, C, D, E)
• For all insulation boards
• For countersunk and surface fixed instalaltion
• For homogeneous surfaces and even rendering
• Up to 40% faster installation
• European Technical Approval (ETA) 

Properties

• Approved for all building materials
• Countersunk installation - EJOT STR principle with ejotherm STR cap for homogeneous surfaces and even rendering - quick and easy without milling dust
• Up to 40% fastener installation
• Reduced thermal transmission (0.001 W/K)
• Surface fixed installation using ejotherm STR plug
• Short embedment depths, high loads for maximum safety and economic anchor usage
• Permanent contact pressure
• Premounted screw for quick installation
• 100% setting control: the countersunk installation of the washer indicates safe anchorage
