The TIMCO Heavy Duty Engineered Restraint Strap is designed to provide reliable structural restrai...The TIMCO Heavy Duty Engineered Restraint Strap is designed to provide reliable structural restraint between timber floors, joists, rafters, and masonry walls. Its engineered lightweight construction allows for easier handling on-site while maintaining the strength required for both horizontal and vertical restraint applications. Manufactured from galvanised carbon steel, the strap offers excellent corrosion resistance and long-term durability for internal and sheltered structural installations. The strap is suitable for various applications, including the restraint of timber floor joists to masonry walls, connecting roof trusses or rafters to brick or blockwork, and general lateral restraint against wind loads and structural movement. It features multiple fixing holes for flexible positioning and is manufactured in accordance with BS EN 845-1. Specifications include a total length of 1600mm, a strap length of 1500mm, a 100mm bend, 36mm width, and 1.4mm thickness. It includes 30 nail holes and 20 screw holes.
The TIMCO 1600mm Heavy Duty Engineered Restraint Strap is an essential structural component for professional builders and contractors tasked with tying timber floor joists, rafters, or roof trusses to masonry walls. Offering robust lateral restraint against wind loads and structural movement, it provides reliable stability for new builds and renovations alike. While it offers superior galvanised steel protection for sheltered areas, it is important to note that the product is intended for internal or sheltered installations rather than exposed coastal or highly corrosive outdoor environments.

Troubleshooting
Strap appears slightly loose after installation
Ensure that the timber has been pre-drilled if necessary to prevent splitting and that all nails or screws are fully driven to ensure a tight connection.
Difficulty aligning holes with joists
The strap features multiple fixing holes specifically to accommodate variations in joist spacing; verify the strap is centered and utilize the most appropriate row of holes.
Pros and Cons
Pros
Meets BS EN 845-1 building standards
Lightweight construction reduces on-site fatigue
High volume of pre-drilled holes for flexible fixing
Excellent corrosion resistance for sheltered structural use
Cons
Not suitable for direct exposure to severe weather or harsh coastal environments
Requires specific masonry fixings which are sold separately
Fixed 100mm bend may require additional onsite adjustments for non-standard wall depths
Setup, Compatibility & Care
Installation Steps
Positioning: Align the strap so the 100mm bend sits flush against the masonry wall, while the main length runs across the timber joists or rafters.
Fixing to Timber: Use appropriate structural screws or annular ring shank nails in the designated fixing holes. Ensure every required hole is filled to meet load-bearing specifications.
Fixing to Masonry: Anchor the bent end into the masonry wall using heavy-duty wall plugs or resin anchors compatible with the substrate.
Compatibility
Suitable for timber floor joists, roof rafters, and trusses.
Compatible with brick and blockwork masonry.
Care
Store in a dry, covered area prior to installation to prevent premature oxidation.
If the galvanised coating is scratched during installation, treat the area with a cold galvanising spray to maintain integrity.
