A lower plate bolts down flat to a concrete or masonry base; an upper plate, raised and lowered by turning the nut on the central M24 threaded rod, carries the timber post itself. Because the post is fixed to a plate rather than dropped into a socket, it doesn't need to be cut or machined to length before fitting; the finished height is simply set on site once the post is in position, which is particularly useful where a slab, patio or paved area isn't perfectly level. The whole bracket is manufactured from zinc-plated S235 structural steel for reliable general-purpose corrosion resistance outdoors, and is designed for vertical structural loads, in line with the European Technical Assessment (ETA) requirements that apply to this type of construction connector.\u003c\/p\u003e\n\u003cp\u003eThe bracket is offered in three post fitting widths: 80mm (3.15in), 100mm (3.94in) and 130mm (5.12in), so it can be matched to the actual cross-section of the timber being used, from a standard fence post up to a heavier pergola or veranda upright. Height adjustment, plate thickness and the M24 fitting are held constant across all three sizes, so the same fixing method and tools apply whichever size is chosen.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCentral M24 threaded rod gives up to 250mm (9.84in) of height adjustment, even after the base plate has already been bolted down\u003c\/li\u003e\n\u003cli\u003eTwo-plate jack design: a lower plate anchors to the concrete or masonry base, an upper plate carries and adjusts the post\u003c\/li\u003e\n\u003cli\u003eNo cutting or machining of the post required before fitting; finished height is set on site to suit an uneven or sloping base\u003c\/li\u003e\n\u003cli\u003eManufactured from zinc-plated S235 structural steel for reliable general-purpose corrosion resistance outdoors\u003c\/li\u003e\n\u003cli\u003eM24 hex nut (class 10) included, finished in the same zinc-plated coating as the rest of the bracket\u003c\/li\u003e\n\u003cli\u003eDesigned for vertical structural loads, in line with European Technical Assessment (ETA) requirements for this type of connector\u003c\/li\u003e\n\u003cli\u003eAvailable in three post fitting widths: 80mm (3.15in), 100mm (3.94in) and 130mm (5.12in), each with four pre-drilled corner holes top and bottom\u003c\/li\u003e\n\u003cli\u003eConsistent 4.0mm (0.157in) plate thickness across the range for a rigid, low-flex base\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003ePost fitting width\u003c\/th\u003e\n\u003cth\u003eHeight adjustment\u003c\/th\u003e\n\u003cth\u003ePlate thickness\u003c\/th\u003e\n\u003cth\u003eApprox. weight\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e80mm (3.15in)\u003c\/td\u003e\n\u003ctd\u003e250mm (9.84in)\u003c\/td\u003e\n\u003ctd\u003e4.0mm (0.157in)\u003c\/td\u003e\n\u003ctd\u003e1.15kg (2.52lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100mm (3.94in)\u003c\/td\u003e\n\u003ctd\u003e250mm (9.84in)\u003c\/td\u003e\n\u003ctd\u003e4.0mm (0.157in)\u003c\/td\u003e\n\u003ctd\u003e1.51kg (3.32lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e130mm (5.12in)\u003c\/td\u003e\n\u003ctd\u003e250mm (9.84in)\u003c\/td\u003e\n\u003ctd\u003e4.0mm (0.157in)\u003c\/td\u003e\n\u003ctd\u003e1.98kg (4.35lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe height-adjustment rod is an M24 threaded bar secured with a matching M24 hex nut (class 10), both finished in the same zinc-plated coating as the rest of the bracket, confirmed via manufacturer technical drawings for all three sizes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis bracket is designed for above-ground timber post bases carrying vertical structural loads.
