Fixing battens to string-board - uses screw to secure plate clamping elastic strap onto board between battens

摘要

The fixing system uses an elastic strap (a) to secure battens (b) demountably on a string-board (c), using a screw (s) sited in a gap between battens to pull a retaining plate (d) onto the board. The screw may pass through a strap hole hole in the board, and may be driven into the ferrule to clamp the strap between the plate and the board.
