2. Contact EDWARDS DOOR SYSTEMS LIMITED for further product information and/or quotations at - 1-888-786-5623 - Sarnia - London - Toronto

3. All aluminum components shall be extruded aluminum alloy 6061-T6

4. Deflection under live load:
   The foot grilles shall be so conceived so as to accept a minimum uniform load of 730 Newton applied over a 4 square inch (100mm) surface in order to obtain a 1/180" deflection over a 4'-0" (1220 mm) span.

5. The perimeter frames shall be an inverted "T" shape such as model "VV" by Bolar, in order to anchor the structure into the concrete. For sections larger than 6'-0 * 8'-0 ( 2000mm * 2400mm ) a mechanical joint is to be provided, (if specified).
   OR
   The perimeter frames shall be " L " shaped such as model "AD" by Bolar, for existing openings. For sections larger than 6'-0 * 8'-0 (1828mm x 2438mm) a mechanical joint is to be provided (if specified).
   OR
   The perimeter frames shall be "Z" shaped such as model "TT" by Bolar. For installation over finished floor surfaces. For sections larger than 6'-0 * 8'-0 (1828mm x 2438mm) a mechanical joint is to be provided (if specified). A silicone joint is to be applied between the frame and the finished floor to prevent any water infiltration (by others).

6. Blades shall be "T" shaped, size: 3/8" * 1/8" * 3/4" (9.5mm * 3mm * 19mm). Spacing between blades is not to exceed 3/16" (4.7mm). Such as model BA-3/4 by Bolar. Overall depth: 1 3/4" (45mm) from finished floor.

7. Spacing between blades and retaining rods shall be so as to meet manufacturer's specifications for the minimum weight capacity. Foot grille will be manufactured in sections so as to increase ease of maintenance.

8. The frames will be supplied with a pan. Pan shall be of 20 gauge stainless steel, no drain.
   OR
   The frames will be supplied with a pan. Pan shall be of 20 gauge galvanized steel. Coat all surfaces in contact with masonry with two coats of bituminous paint.
   OR
   The frames will be supplied without a pan. A coat of waterproofing is to be applied to the concrete base to avoid water infiltration (by others).

9. The sections shall have a friction coefficient of 1,22 and a cleaning efficiency of 49 %, percentage of opening shall be 40%.

10. The deformation under lateral charge is not to exceed 8 (visual) after application of a maximal charge of 6130 Newton (1380 pounds) at a 45 degree angle in relation to the surface.

11. All sections shall be in accordance with ASTM B117 norms, and be able to sustain a 1000 hours salt fog without any notable changes.

12. Manufacturer shall be able to confirm this data and be able to supply architect with all necessary reports and shop drawings.

1. The foot-grille sections will be installed in their frames, as a last item, to prevent damages during construction. Install all foot grilles, square and level with finished floor so as to permit easy manipulation of all sections. All frame members and intermediary supports are to be level and well supported on all their lengths in order to avoid any deflection over a long term period.

2. All frames and pans are to be thoroughly cleaned before installing any grille section in order for them not to exceed finished floor level. All sound gaskets damaged during installation, are to be replaced before final inspection. Protect grilles from construction traffic. Install all hinges (if required). Verify that all latches are in a closed position and properly greased (if required).

Option #1: Hinges and lock notch: [Not applicable for this model]
All sections of grille will be supplied with hinges and lock notch. The hinges and lock notch will be fabricated in stainless steel and installed on the grille by the manufacturer. They will be attached to the frame by the general contractor and verified by the architect prior to final approbation.

Option #2: Hinges and lock notch with GB-46 lock downs: [Not applicable for this model]
All sections of grilles will be supplied with a combination hinges/lock notch and lock downs model GB-46. The hinges and lock notch will be fabricated in stainless steel and installed on the grille by the manufacturer. The lock downs will be fabricated of galvanized steel and Teflon, they will be attached to the grille sections by the manufacturer. The lock downs will be supplied with a special key for easy of operation (one per vestibule). All lock downs have to be greased (BSRS 2000 water resistant)) at the time of installation by the general contractor. We recommend they be greased at least 4 times a year. All systems to be verified by the architect prior to final approbation.

Option #3: Lock downs GB-46 (4 per grilles):
All sections of grille will be supplied with a lock downs mechanism GB-46 (4 per sections of grille). The lock downs will be fabricated of galvanized stele and Teflon, they will be attached to the grille sections by the manufacturer.
