STRUCTURAL TIMBER CONNECTORS / ADJUSTABLE POST BASES

Simpson Strong-Tie ABW66RZ Adjustable Post Base (150mm x 150mm)

The Simpson Strong-Tie ABW66RZ is an engineered, cost-effective adjustable structural timber post support specifically optimised for rough-sawn or full-dimension 150mm x 150mm square timber columns. Designed for maximum versatility, it features a built-in 25.4mm stand-off base plate that mechanically isolates the timber face from the concrete pad. This structural clearance effectively blocks capillary moisture draw and standing water pooling, keeping the timber base completely dry to eliminate moisture-induced rot and fungal decay in exposed Service Class 3 applications.

CRITICAL STRUCTURAL SPECIFICATION: LATERAL RESTRAINT MANDATE

Like all standard stand-off structural supports, the ABW66RZ operates strictly as a pinned structural connection. It is engineered exclusively to resist vertical axial loads, downward forces, and horizontal shear—it is not designed to withstand bending moments or rotational momentum. To maintain structural integrity, the top of the timber post must be rigidly secured via an approved lateral restraint configuration (such as floor diaphragms, cross-bracing, or braced beam structures).

TECHNICAL DATA & DESIGN CAPACITIES

Specification Parameter Engineered Values & Materials
Base Profile Seating 152.4mm x 152.4mm configured for rough-sawn 150mm posts
Stand-Off Ground Clearance 25.4mm absolute timber isolation zone
Material Composition High-performance pre-galvanised mild steel plate assembly
Corrosion Protection Grade Pre-galvanised finish (Optimised for Outdoor Service Class 3 exterior exposures)
Characteristic Capacities R1,k (Downward Vertical Compression) = 110.4 kN | R2,k (Uplift) = 6.6 kN (C24 timber profiles)
Fastener Requirements (Timber) Requires 12 No. structural nails (4.0mm x 90mm driven through provided side flange holes)
Fastener Requirements (Concrete) Requires 1 No. heavy-duty M12 anchor (slotted base compatible with threaded bar, resin or mechanical fixings)

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • Slotted Base Positioning Flexibility: Integrated base plate slot layout permits seamless tolerance adjustments around anchor bolts on site.
  • Advanced Stand-Off Protection: Elevates the column base 25.4mm off the concrete floor, breaking capillary tracking paths to permanently prevent wood decay.
  • Optimised Seating Profile: Specially engineered with an expanded 152.4mm internal seating array to accommodate rough-sawn 150mm structural posts cleanly.
  • Rigid Multi-Plane Load Transfer: Fold-up steel bracket plates fold flush against the side columns to maintain an audited 110.4 kN vertical capacity.

How We Keep Your Builds Moving

We partner with leading heavy industrial parcel and parcel-freight carriers across the country to maintain real-time tracking from our central warehouse shelves straight to your signature pad.

01.
Instant Hub Sorting: Approved orders pass straight to active pick queues via our localised automated barcode stock framework.
02.
Heavy Component Packing: Structural products are safely stored in industrial reinforced crates or strapped securely to custom pallets to fully safeguard fine threads and anti-corrosion zinc surfaces.
03.
Tailgate On-Site Offloading: Bulk shipments drop cleanly at your structural site boundary line via integrated tail-lift carrier transport systems.

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.
