<p>A roller shutter fixing device has a base unit (1) suitable for double widths, fixed to existing walls or wood frames. On both sides it has a box section (1a), on one of its ends and over its full height, for receiving the shutter lugs and for fixing the slideways. The inside face of the base is ribbed (1b) for interlocking with a box section (2) working with bolts (3,4). The other end is for clip-fixing for aligning the plane section for full width or a cover joint. The base support (1) and slide are made of extruded aluminium.</p> |
