摘要
Undercut grooves in posts contain groove blocks. There are screws in them to clamp holders, which grip lengthways-aligned boards from above and below and hold them in place on the grooved side of the posts, in a balustrade or fence. The parts (13) of the board holders (3,4) on the side of the boards (5) away from the posts (1) are spaced away from the posts by board thickness. A pressure unit (16) of durably elastic material, protruding when relaxed, is located in the vertical groove (6) behind the board, to hold the board in position on the holders. This is pref. trough or gutter-shaped.
