STRUCTURAL TIMBER CONNECTORS / MASONRY WALL STARTERS

Simpson Strong-Tie C2KS Crocodile Wall Extension Profile

The Simpson Strong-Tie C2KS is the UK's most popular engineered solution for seamlessly tying new brick or block walls into existing masonry structures. Manufactured from premium austenitic stainless steel, this multi-purpose "no flange" profile is designed to cater to wall thicknesses ranging from 60mm up to 250mm, making it ideal for both internal and external applications where fair-faced brickwork is required on both sides. Featuring a unique, time-saving "snap-out" tie system, anchor ties can be positioned anywhere along the channel to perfectly accommodate variations in brick courses while allowing for 10mm of vertical thermal/structural movement. Fully BBA approved for structures up to 8 metres (3 storeys) in height, it provides ultimate lateral support and structural reliability for extensions, conversions, and new build configurations.

CRITICAL STRUCTURAL SPECIFICATION: INSTALLATION & SPACING MANDATE

To achieve certified load-bearing performance, all specified fasteners must be spaced evenly and anchored directly into the structural brick or blockwork—never into mortar joints. Insert the provided wall ties at a maximum of 300mm vertical centres, ensuring they are fully bedded into the new mortar courses. For single leaves of blockwork, use 1 C2KS kit; for larger wall thicknesses exceeding standard specs, the simultaneous use of two parallel wall starters is structurally recommended. In highly exposed elevations, ensure an additional vertical damp proof course (DPC) is detailed.

Logistics Scope & Out-Of-Zone Shipments

Standard pricing arrays map explicitly to structural mainland UK postal grids. Supplementary transit routing variables, variable lead times, or specialised carrier adjustments apply across high-altitude or outlying maritime zones:

  • Scottish Highlands & Islands: Postcode structures matching KW, IV, PA, and PH configurations map to premium alternative transit grids. Please review checkout calculations for accurate real-time weights.
  • Northern Ireland, Isle of Man & Outer Channels: Specialised water-crossing logistical paths require clean custom manifesting lines.
  • Heavy Oversized Pallets: Extended multi-ply girder connectors, structural space straps, or high-volume masonry hangers exceeding standard bulk dimensions pass through dedicated heavy haulage grids.
*** NEED SPECIFIC AM DELIVERY TIMES OR SITE COORDINATION ARRANGEMENTS *** If your project features demanding time windows, unique site restrictions, or crane offload coordination, contact our central logistics team directly on 01707 375172 or email your schedule over to finalise arrangements.
