<p>A lockâ s strike for a structure is formed from a jamb sheet 51 and a keeper sheet 52. The jamb sheet 51 has a section parallel to, abutting and secured to the structures wall. A bend along its length leads to a section projecting outwards from the wall. A further bend along its length leads to a section parallel to but spaced from the wall. Preferably a final bend leads to a section extending back to the wall. The keeper sheet 52 has limbs and gaps therebetween. It has an has an elongate portion parallel to, abutting and secured to the parallel spaced part of the jamb sheet. From the elongate section extend limbs parallel to the wall of the structure, which then bend towards it, securing to it at their tips. The limbs form channels with the jamb sheet to receive multiple hooked bolts from the door which slide parallel to the length of the jamb. The structure may be a bomb proof bin.</p> |
