发明名称 Wall security fixtures
摘要 A method of forming a wall security fixture of the kind having an elongate rail and a plurality of upstanding palings connected to the rail. In the method, a flat sheet of material is punched to form a series of flat, intermediate paling members which are located side-by-side in complementary relationship. The individual intermediate members are then folded about an axis of symmetry to form V-shaped palings which have outwardly splayed end portions which can be welded or otherwise fixed to the web of a channel-shaped rail to secure the paling to the rail. The invention extends to wall security fixtures formed according to the method.
