Figure B Top Side Drill Screw Pattern | II. Invisi-Loc® Underside Fastening System Invisi-Loc® provides showcase mezzanine floors with no visible fasteners that are dependable, inexpensive and easy to install. They reduce installation time in drilling and eliminate metal shaving safety concerns. The Invisi-Loc fastening system mounts fasteners under mezzanine decking hiding unsightly screw holes on top. Invisi-Loc fasteners have been tested with over 12 years of simulated pallet jack traffic resulting in no fastener or panel failures. (Cornerstone tests were based upon 50,000 cycles/12 years of pallet jack wheel traffic at specified ResinDek® loads). 24 Invisi-Loc fasteners (see figure A) are required per 4' x 8' sheet and a standard medium duty air compressor supplies the required power. All installation tools can be rented or purchased from Cornerstone Specialty Wood Products LLC. Figure A
Invisi-Loc® Underside Fastening System |  | | How it Works:
Corrugated metal decking is pre-punched and B metal deck is fastened to the bar joists like other steel decking using drilling screws or welding.
During installation of mezzanine decking, ResinDek® panels are laid down with metal panel spacers. Special drill bits for pre-drilling the ResinDek® panels to the precise depth and diameter are then used to pre-drill for the Invisi-Loc fasteners. With weight applied to the top surface, the Invisi-Loc fasteners are mounted to the underside. When installed according to Cornerstone specifications the Invisi-Loc Underside Fastening System carries a 7-year warranty. |  | Please contact Cornerstone Specialty Wood Products LLC for product details, warranty, tool sales, and rentals.
