STRUCTURAL TIMBER CONNECTORS / JOIST REINFORCEMENT & PROTECTOR KITS

Simpson Strong-Tie SNRK Solid Joist Notch Reinforcement Kit (Pack of 5)

The Simpson Strong-Tie SNRK is an engineered retrofit kit designed to restore structural integrity to solid timber floor joists where top notches have been cut for plumbing pipes, electrical conduit, and HVAC runs. Commonly required in bathroom refurbishments and service routing, notching solid wood members significantly weakens the timber and exposes buried services to accidental penetration from floorboard fixings. Constructed from 1.2mm pre-galvanised mild steel, each SNRB bracket features an innovative bendable side leg that easily wraps around existing pipes and cables. The heavy-duty top plate acts as a physical shield over the notch while structural side fixings help recover up to 75% of original joist strength (when tested to BS EN 408). Each boxed kit contains 5 reinforcement brackets and 28 dedicated CSA4.0x30mm connector screws—enough to fully protect 5 notched floor joist positions.

RECOMMENDED INSTALLATION FASTENERS

To achieve certified load performance and ensure physical protection against accidental screw penetration, the SNRK must be fixed exclusively using the included Simpson Strong-Tie CSA4.0x30mm connector screws. All pre-drilled 5mm bracket holes must be filled during installation. Do not substitute with standard drywall or woodscrews.

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.
