Bent restraint straps at this spec are what the regs actually call for when you are tying roof trusses, rafters and joists back to masonry. These are 40mm x 5mm heavy duty straps, pre-bent at 100mm, and manufactured from A2 stainless steel throughout. Available in 1000mm and 1200mm lengths to suit different structural situations, they are supplied in a 10 pack — useful when you are working across a full roof rather than fixing a single point.
The A2 stainless steel construction is not just a nice-to-have. Building Regulations and BS 5268 Part 3 specify stainless steel in corrosive environments, and that covers more situations than most people assume. Green oak, for instance, is notoriously aggressive to standard mild steel fixings — the tannins will get to work on them well before the structure is even closed in. Any coastal or high-humidity exposure tells a similar story. Stainless eliminates that risk entirely.
Where Bent Restraint Straps Are Used on Site
The standard application is horizontal restraint — roof trusses, cut rafters and floor joists tied back into a blockwork or brick leaf. The pre-formed 90-degree bend seats flat against the wall plate or joist while the strap runs across to the masonry, giving you a clean, code-compliant fixing without any site bending. That matters when a Building Control inspector is due on Thursday and you need everything done properly rather than just done quickly.
Sizing on Site
The 1000mm length covers most standard truss-to-masonry applications. The 1200mm option gives you extra reach where there is a wider cavity, a deeper wall plate, or the geometry just does not play ball. Worth having both sizes to hand if you are working on a larger project rather than ordering twice.
These bent restraint straps are priced per 10 pack, making them straightforward to cost into a job without carrying individual strap prices through a bill of quantities.
Pro Tip: When fixing into the masonry leaf, use A2 stainless fixings throughout — mixing stainless straps with standard zinc-plated screws defeats the point entirely, especially in green oak or high-humidity environments.
