Extended Product Information
FAQs
What is the primary purpose of this strap?
The primary purpose is to provide lateral restraint, preventing roof trusses, rafters, or joists from moving sideways when they are tied into masonry walls.
Is this strap suitable for vertical applications?
No, this specific model is designed and intended for horizontal installation only. Different products are available for vertical restraint.
What material is the strap made from?
The strap is manufactured from pre-galvanised mild steel, offering good durability and corrosion resistance.
What are the dimensions of this strap?
The dimensions are 28mm in width, 600mm in length, and 4mm in thickness.
Does the product come with screws or anchors?
No, the strap itself is supplied without fasteners. You will need to select and provide appropriate structural screws for timber and suitable anchors for the masonry wall, in accordance with local building codes.
Can I cut the strap to a custom size?
While metal can be cut, it is generally recommended to use the product as manufactured or select a size from the available increments to ensure its structural integrity and compliance with intended use.
What is the advantage of pre-galvanised steel?
Pre-galvanised steel has a protective zinc coating applied during manufacturing, which helps to prevent rust and corrosion, extending the lifespan of the product in construction applications.
Troubleshooting
Strap does not fit snugly against both surfaces.
Ensure the timber and masonry surfaces are reasonably flat. Check for any debris or obstructions. If necessary, a small shim may be used, but the primary goal is direct contact.
Difficulty in securing fasteners.
Verify that the correct type and size of fasteners are being used for both the timber and masonry. Ensure pilot holes are correctly sized for the fasteners. Check that the masonry is sound and not crumbling.
Corrosion observed on the strap.
Minor surface rust on the galvanised coating may occur but is usually superficial. For significant corrosion, the strap may need to be replaced. Ensure proper ventilation around the installed area if moisture is a contributing factor.

Setup, Compatibility & Care
Setup:
- Position the strap horizontally, ensuring it aligns correctly with the structural members (truss, rafter, joist) and the masonry wall.
- Mark the pre-drilled holes onto the timber and masonry.
- Secure the strap using appropriate fasteners (e.g., structural screws for timber, masonry anchors for the wall). Fasteners are typically not included and should be selected based on local building codes and the materials being joined.
- Ensure all connections are tight and the strap is firmly seated against both members.
Compatibility:
- This strap is designed for use with timber structural members (trusses, rafters, joists) and masonry construction.
