Simpson Strong-Tie horizontal restraints meet the requirements for lateral restraint of roof truss...Simpson Strong-Tie horizontal restraints meet the requirements for lateral restraint of roof trusses, rafters and joists tied into masonry walls. Designed for tying roof timbers into masonry, the Simpson Strong-Tie H10T10 Heavy Duty Lateral Restraint Strap provides lateral restraint for roof trusses, rafters and joists where a secure horizontal fixing is required. Intended for horizontal installation, it supports compliant detailing when connecting structural members back to masonry walls. Made from pre-galvanised mild steel, this twisted restraint strap is supplied in a 1000mm overall length and can be set out in 100mm increments to suit your installation requirements. Overall Length: 1000mm. Size: 28 x 1000 x 4mm.
The Simpson Strong-Tie H10T10 Heavy Duty Lateral Restraint Strap is designed for builders and contractors needing a secure horizontal connection between roof timbers and masonry walls. Its primary benefit is providing compliant lateral restraint, ensuring structural integrity. A key consideration is its specific application for horizontal fixing, requiring proper installation to achieve its full potential. This twisted strap, made from pre-galvanised mild steel, offers adjustability in 100mm increments along its 1000mm length.

FAQs
What is the primary purpose of the Simpson Strong-Tie H10T10 strap?
The H10T10 is designed to provide lateral restraint for roof timbers (trusses, rafters, joists) where they connect horizontally to masonry walls, helping to prevent sideways movement.
What material is the H10T10 strap made from?
It is made from pre-galvanised mild steel, which offers good durability and resistance to corrosion.
Can this strap be used for vertical connections?
No, the H10T10 is specifically designed for horizontal installation and horizontal restraint.
What is the overall length of the strap and how is it adjusted?
The strap has an overall length of 1000mm. It can be set out or used in 100mm increments, offering some flexibility in positioning the fixing points.
Does the H10T10 come with fasteners for installation?
No, the strap itself does not include fasteners. You will need to supply appropriate structural screws or nails for attaching to timber and suitable masonry anchors for attaching to the wall.
Is the pre-galvanised finish sufficient for outdoor exposure?
The pre-galvanised finish provides good protection against corrosion for typical structural applications. For highly aggressive or continuously exposed environments, additional protective measures or specific coatings might be considered, though it's generally suitable for its intended use within building structures.
How do I ensure the connection is structurally sound?
Ensure the strap is correctly positioned horizontally, securely fastened to both the timber and masonry using appropriate, load-rated fasteners, and that the installation complies with local building codes and any specific engineering requirements for your project.
Troubleshooting
Strap does not reach desired length.
The H10T10 has a maximum length of 1000mm and can be set out in 100mm increments. If a longer span is required, consider using multiple straps or a different product designed for longer reach.
Difficulty securing strap to masonry.
Ensure you are using the correct type of masonry anchor for the wall material. Verify the anchor is suitable for the load and has been installed according to the anchor manufacturer's instructions. The strap itself does not come with masonry fixings.
Rust spots appearing on the strap.
Minor surface rust may occur on the galvanised coating over time. Clean gently with a wire brush if necessary. If significant corrosion is present, the strap may need replacement depending on structural impact.
Pros and Cons
Pros
Provides essential lateral restraint for roof structures connected to masonry.
Durable construction with pre-galvanised mild steel.
Designed to meet specific building code requirements for structural connections.
Clear application for horizontal fixing scenarios.
Cons
Primarily suited for horizontal fixing applications.
Requires appropriate fasteners for secure attachment (not included).
May not be suitable for all types of structural connections or materials.
Specific expertise may be needed for complex structural designs.
Length is fixed at 1000mm, though adjustable within that range.
Setup, Compatibility & Care Instructions
Setup:
Positioning: Determine the required horizontal connection point between the timber member (truss, rafter, joist) and the masonry wall.
Attachment to Timber: Securely fasten one end of the H10T10 strap to the timber member using appropriate structural screws or nails. Ensure the fasteners penetrate sufficiently into the wood for a strong hold.
Attachment to Masonry: Anchor the other end of the strap to the masonry wall. This typically involves using masonry anchors (e.g., expansion bolts, lag shields) suitable for the type of masonry and the expected load.
Adjusting Length: If a precise 100mm increment is needed, the strap can be positioned accordingly. For secure fixing, ensure the strap is taut and without significant slack.
Compatibility:
This product is designed for use with timber roof trusses, rafters, and joists.
It is intended for connection to masonry walls (brick, block, concrete).
Always consult local building codes and structural engineering specifications to ensure this product is appropriate for your specific application and load requirements.
Care:
The pre-galvanised finish provides inherent corrosion resistance. Regular inspection is recommended, especially in damp environments.
Clean any accumulated dust or debris with a dry cloth.
Avoid harsh chemicals or abrasive cleaners, which could damage the protective coating.
