The 3200 range tie is a versatile, multi-purpose frame cramp designed in accordance with the requirements of BS EN 845-1. This tie allows a masonry panel to be tied back to various structures or substrates, which means it can serve a range of applications on site. Notably, the tie is designed to exceed the requirements of a Type 2 cavity as described by PD6697.
The tie is engineered to resist water crossing a cavity, thanks to the integrated ‘drip’ features that prevent the transgression of water from the outer leaf to the inner leaf of a building. This is even effective when installed at an angle of up to 5° in an unfavorable direction. The tie is intended for use in a minimum mortar joint thickness of 10mm.
A variety of corrosion-resistant fixings is available to suit different applications. The list below represents typical fixings used. For more information or alternative fixings, please contact the technical department.
- Concrete: M6 Stainless Steel (S/S) Coach Screw & SX8 Plug, M6 S/S Expansion Anchor
- Steel: M5.5 BZP Self Drilling Tech Screw
- Block: M6 S/S Coach Screw & SX8 Plug
- Timber: M6 S/S Coach Screw, NO 12 Posi Pan Head S/S Wood Screw
Installation & Best Practice:
Wall ties should typically be installed at a density of at least 2.5 ties/m2 for walls where both leaves are thicker than 90mm. This density can be achieved by spacing the ties at 900mm horizontal centers and 450mm vertical centers, staggered at alternate courses.
Wall ties should be evenly distributed across a wall, with the exception of areas around openings or at an un-bonded panel edge. In these areas, the tie density should be increased to 225mm vertical centers within 225mm of the opening or edge.
The length of the tie should be sufficient to allow an embedment of at least 62.5mm. This ensures that the minimum embedment of 50mm is always achieved, even after accounting for site tolerances.
The 3200 range tie is a reliable, versatile, and efficient solution for securing masonry panels, offering superior performance across a variety of construction projects.
