2-Tier Straight Railway Sleeper Bracket with Stake This 2-Tier Straight Railway Sleeper Bracket is a quick and easy system for mounting railway sleepers as driveway or pathway edging, straight edge, building raised beds and planters, securing retaining walls and border edging, and many other simple constructions. Specifically, our 2-Tier brackets are suitable for use in constructions where sleepers will be stacked on top of one another to make taller raised beds or path edging. The extended plate on the top allows for 8 screws to be used to secure the bracket. To install, you must simply bang the stake into the ground where the sleeper is to be installed, we recommend a rubber mallet for this, then just screw the bracket onto the timber sleepers.
