USES: To supplant & eliminate concrete screws & Rawlplugs® - expansible wall inserts, used for fastening items to masonry walls.
ADVANTAGES:
1. Saves time, labour & costs on repetitive accurate masonry screw fixing tasks. 2. Instant alignment in one go, after each drilling using fixture items' holes only.
3. Eliminates additional alignment templates requiring removal to insert wall plugs.
4. Eliminates separate boxes for screws & separate boxes for mating wall plugs.
5. Eliminates frustrations arising from mismatch of right screw / wrong wall plug.
6. Requires smaller diameter drilled holes than the fatter wall plugs they eliminate. 7. Stronger - 360° resilient anchorage v/s quadruple faceted Rawlplugs® contact.
