Part 2 Products

Fittings
Top and bottom fittings will be of cast structural alloys with formed cover plates to match desired finish. All assembly connections will have stainless steel threaded inserts or utilize roll thread fasteners. All assemblies will be constructed of high-density, hardened aluminum castings capable of achieving maximum clamping force.

Glass
Glass will be (Specify one of the following):

• 3/8" or 1/2" thick, fully tempered, clear, gray, bronze, or low iron.
• 3/4" thick, fully tempered, clear.

Glass will conform to requirements set forth by ASTM Specifications C1036 and C1048 for fabrication and tempering. All exposed edges will be flat-polished to a reflective appearance similar to the glass surface. The glass adjacent to or above the door, along with that of the door, must be supplied by the entrance manufacturer to ensure a proper fit and alignment. It is highly recommended that the entrance manufacturer supply all-glass for the entire all-glass opening to ensure a uniform color match of the glass.

Finishes
All exposed surfaces will be free of scratches and other serious blemishes. Rail, channel and pan cover finishes will be (Select one of the following):

• For extruded aluminum, an Architectural Class II clear anodic coating conforming with Aluminum Association standards.
• An Architectural Class I color anodic coating, conforming with Aluminum Association standards. Color: black.
• An Architectural Class I color anodic coating, conforming with Aluminum Association standards. Color: dark bronze.
• A fluoropolymer paint coating conforming with the requirements of AAMA605.2. Color will be (Specify):
• Stainless Steel clad using an alloy 304 finished as follows (specify one): polished or satin.
• Brass/Bronze clad finished (samples required) as follows (specify one): polished or satin.

Hardware
Due to the necessary interaction of entrance components, it is imperative that all hardware be supplied and/or coordinated by the entrance manufacturer. Hardware for the TVC entrance will be furnished by the entrance supplier. Where practical, all hardware fittings will be installed at the factory before the shipment will be made. Hardware will be the entrance manufacturer's standard, as follows:

1. Top corner patch:
2. Bottom corner patch or full rail:
3. Transom and sidelite patches based on entrance design:
4. Patch locks or bottom rail lock, if rail:
5. Pivots and/or door closers:
6. Handles:
7. Exit devices:

For all above, specify manufacturer, model, style, type, finish, etc. as appropriate. If lock cylinders are to be master keyed, it is suggested that cylinders be included under the "Finish Hardware" section of the specifications.

Editing notes � All Glass Swing Doors

Hardware Schedule references may be needed. Coordination of the selected hardware with All Glass doors is needed to confirm that the specified hardware is compatible with the All-Glass door selected.
Type P Glass doors can accommodate most closers including automatic and power assisted closers. This type can also most readily accommodate electric and magnetic locks.
Exit devices for all glass doors are limited to the mechanical Blumcraft H -100 and H-110 Panic series or the electronic CHMI "Smart-Touch" series.

Door Styles

	Type P:	Continuous horizontal top and bottom rails
	Type BP:	Continuous horizontal bottom rail with top corner fitting on pivot side.
	Type A:	Corner fittings top and bottom on the pivot corners. (No locks available)
	Type F:	Corner fittings top and bottom on the pivot corners plus a lock fitting on active side of the door. Usually on the bottom near or at the corner, but can be on the jamb locking into the doorjamb or a strike housing mounted on a sidelight.

Patch fittings can be the European Style (2" x 6") or a rail patches 3 5/8" x 9", 12", or 14" inches long. Patch fittings are extruded aluminum or cast aluminum with stainless steel inserts. Patch fittings may be clad or have covers to match the specified finish.

MAINTENANCE. Closer maintenance is usually routine and is covered in the closer manufacturer's instructions.
A special caution must be observed if the specified hardware finish is Brass, Bronze or other Copper alloy. Since all of these alloys contain copper, they will oxidize (tarnish) in time due to moisture and other chemicals present in the air. A regular maintenance schedule of cleaning with an off-the-shelf brass or metal cleaner will easily return the metal to its natural appearance. If left too long a professional metal restoration company may be required to return the finish to its original appearance. Protective lacquers can be specified, but these coatings are only temporary and are susceptible to scratching in heavy traffic areas and may need to be refinished frequently. Oldcastle Glass does not offer a lacquered finish.
