Key Features

• Bent Design for Versatility:
  The pre-formed bend makes this strap ideal for applications requiring an offset connection, such as tying wall plates to masonry walls or connecting joists at an angle. The shape facilitates installation in corners or stepped configurations.
• Formed Edge for Added Strength:
  The formed edge adds stiffness and increases load resistance at the bend, enhancing overall structural integrity without adding bulk.
• 1.5mm Galvanised Steel Construction:
  Made from corrosion-resistant galvanised steel, the strap offers a durable and long-lasting solution for indoor and sheltered outdoor use.
• CE Marked:
  Fully CE certified for compliance with EU regulations, ensuring quality assurance and traceability.
• BS EN 845-1 Compliant:
  Designed and manufactured to comply with BS EN 845-1, the British Standard for masonry wall ties, straps, and fixings. This makes it suitable for regulated construction and structural installations.

Applications

• Providing vertical restraint to wall plates on top of masonry walls
• Lateral restraint of timber floors or roof structures to walls
• Suitable for use with timber joists, rafters, and other timber members
• Ideal for domestic dwellings and small-scale commercial buildings
• Used in cavity wall construction and traditional masonry

Installation Guidance

• Orientation:
  The bent strap should be installed with the flat section fixed securely to the timber and the bent section fixed to the masonry, depending on the specific layout of the structure.
• Timber Fixing:
  Use four 4mm x 75mm nails or equivalent structural screws for securing to timber. Fix to at least three timber members, using noggings and packing where necessary.
• Masonry Fixing:
  For secure anchorage into masonry, use hardened nails (8SWG x 75mm) or No. 12 screws with wall plugs. Always ensure the bottom fixing is located within 150mm of the end of the strap for proper load transfer.
• Spacing:
  Vertical restraint straps should typically be at least 1m long. Straps should be installed at no more than 2m intervals along the wall.
• Important Note:
  Ensure the flat face of the strap is in full contact with the timber surface for optimal strength and alignment.

Benefits

• Simple and reliable solution for light-duty structural restraint
• Strong and durable construction ensures long-term performance
• Versatile bent profile accommodates varied structural layouts
• Fully certified and compliant with UK and EU building regulations
• Lightweight and easy to handle for quick on-site installation

Frequently Asked Questions (FAQ)

Q: What does the bent design achieve?
A: The bent design allows the strap to be fixed in areas where an angled or stepped connection is required, such as joining timber to masonry at varying heights or recesses.

Q: Can this be used externally?
A: While the strap is made from galvanised steel and is corrosion-resistant, for fully external applications in exposed environments, stainless steel versions are recommended for maximum weather protection.

Q: Is this strap suitable for structural applications in regulated construction?
A: Yes, it is CE marked and conforms to BS EN 845-1, meaning it meets all required standards for use in regulated structural masonry construction.

Q: How does this differ from heavy-duty straps?
A: This light-duty strap is thinner (1.5mm) and designed for lighter load-bearing situations. Heavy-duty alternatives are thicker (typically 2.5mm or more) and used in applications requiring greater structural reinforcement.

Q: How is this strap typically used on-site?
A: It is commonly used to tie wall plates down to masonry or to provide lateral support between joists and walls in timber-framed or cavity wall construction.
