12" x 12" Order Size

NGP defines the specified lite-kit size as the:

Door Cutout & Order Size

For this 12" x 12" kit:

Door Cutout / Order Size: 12" x 12"
Cut Glass Size: approximately 11" x 11"
Exposed / Visible Glass: approximately 10" x 10"

NGP specifies:

Cut Glass = Order Size Less 1"
Exposed Glass = Order Size Less 2"

This distinction is important when matching an existing door cutout or determining visible-glass area.

Protect3™ Fire-Protective Safety-Wired Glass

The included Protect3 glazing is:

Thickness: 1/4" / 6mm

and incorporates:

• 3/4" x 3/4" diamond-pattern electrically welded steel wire mesh

• Heavy-duty fire-rated and impact-safety-rated film

• UL classification etched on each piece

• Construction designed to maintain integrity when fractured or exposed to the required hose-stream test

• Approximate weight of 3.6 lb per square foot

• STC 28 rating

Protect3 is not simply traditional wired glass—it incorporates an applied safety film so the glazing can meet current impact-safety requirements.

Impact Safety Rated

NGP Protect3 glass meets:

• ANSI Z97.1 Class A

• CPSC 16 CFR 1201 Category I & II

• Applicable IBC requirements for use in doors

This makes the glazing suitable for applicable commercial door vision-panel applications requiring safety glazing.

Fire-Rated Applications

NGP publishes Protect3 for fire-protective applications when installed with the appropriate listed lite kit and glazing materials.

Applicable standards include:

• ANSI/UL 9

• ANSI/UL 10B

• ANSI/UL 10C

• CAN/ULC-S104

• ULC CAN4-S106

For 60- and 90-minute doors, NGP limits Protect3 to:

Maximum Visible Glass Area: 100 sq. in.
Maximum Visible Width: 12"
Maximum Visible Height: 33"

Because this 12" x 12" order-size kit provides approximately 10" x 10" exposed glass, the visible area is approximately 100 square inches—matching NGP's published maximum visible area for applicable 60- and 90-minute door applications.

The complete door, frame, glass, lite kit, glazing material, installation, and labeling must all comply with the required fire-door listing.

L-FRA100 Steel Frame

The L-FRA100 frame features:

• 18-gauge cold-rolled steel

• Mitered and welded corners

• Welded corner reinforcing clips

• Countersunk mounting holes

• Low-profile architectural design

• #8 Phillips-head mounting screws

• Gray Primer powder-coat finish

The frame is designed specifically for 1-3/4" thick hollow metal or wood doors, within normal door-industry thickness tolerances.

GPZ Gray Primer Finish

Standard finish:

GPZ – Gray Primer Powder Coat

The neutral primer-gray finish provides a clean commercial appearance and can coordinate with common primer-gray hollow metal doors and frames.

Additional factory powder-coat colors are available separately.

NGP L-GT-118
