Product Details

SAMAC Stainless Steel Safety Frame Cramps are designed to provide a secure and durable fixing between timber frames and masonry, ensuring long-term structural stability in cavity wall construction. Commonly used for door and window installations, these cramps are fixed to the frame and built into mortar joints, creating a strong mechanical restraint while allowing for natural movement within the structure.

Manufactured from austenitic stainless steel (typically Grade 304), these cramps offer excellent corrosion resistance, making them suitable for both internal and external applications, including exposed environments. The safety-ended design improves handling on site and ensures safer installation, while maintaining consistent embedment within the mortar joint. Frame cramps are widely used to restrain masonry to structural elements such as concrete, steel, or existing walls, preventing lateral movement and improving overall build integrity
