The edging blocks for lawns and flowerbeds have an L-shaped cross-section. The upright arm (2) has a tongue (7) on one end face and a groove (6) on the other, allowing adjacent blocks to be fitted together in a line. The horizontal arm (3) has strips (4) at each end with grooves (11) which allow the blocks to be fastened together with bolts.
