This product is a 2-piece sanding block set sized 128 x 69 mm intended for hand sanding and surface preparation. Each block is used to hold abrasive paper flat and provide a controlled, even hand pressure across timber, paint, filler and metalwork. The primary use case is manual sanding in workshop and site environments where consistent contact and a comfortable hand grip improve finish quality and reduce operator fatigue.

The blocks have a rigid moulded polymer body manufactured from glass‑filled polypropylene for good stiffness and impact resistance, with a soft thermoplastic rubber (TPR) overmoulded grip for secure handling. A closed‑cell foam backing provides even pressure distribution and protects the abrasive. The design uses clamping edges to accept standard 128 x 69 mm abrasive sheets; there are no threads, heads or drive types applicable to this hand tool. Production follows recognised quality management practices and component tolerances consistent with general workshop tooling standards (manufactured under ISO quality systems).

Typical applications include finish sanding of wood prior to sealing or varnishing, scuffing and feathering of paintwork in automotive and marine repair, smoothing filler and plaster, and light deburring or hand‑finishing of metal components. The product is suitable for trades including carpentry and joinery, automotive refinishing, general maintenance, boatbuilding and DIY. The two‑piece set commonly comprises one firmer block for flat surfaces and one slightly softer, foam‑backed block for gentle contour work and profiling.

Key benefits include superior corrosion resistance compared with metal sanding blocks (the polymer construction will not rust), a robust stiffness that ensures consistent abrasive contact, and ergonomic grips for reduced hand strain during prolonged use. Compatibility with standard 128 x 69 mm abrasive sheets makes it easy to swap grits as work progresses, and the twin‑block set provides flexibility for different surface geometries.

Duchy Fasteners stocks the 128 x 69 mm sanding blocks in 2‑piece packs; alternative single blocks and other sanding block sizes are also available—contact us for pack quantities and bulk options.
