Extra Strong Standard Railway Sleeper Corner Brackets ----------------------------------------------------- Our brackets provide a quick and very easy system for mounting and joining railway sleepers for garden construction work. Our unique design is cheap, quick to install, and works with all sizes of timber railway sleepers. These brackets are a quick and easy system for mounting railway sleepers as driveway or pathway edging or straight edges, as well as building raised beds and planters, securing retaining walls and border edging, and many other simple constructions. Our brackets are typically made from 2mm thick steel, but these extra strong brackets are made from 2.5mm thick steel. That extra 0.5mm provides amazing amounts of strength, meaning these brackets can be used for heavy-duty installations.
