NGP L-SG100 10X10 – Frequently Asked Questions

1) Will the NGP L-SG100 security grille lite kit work on a 1-3/4 inch door?
That's exactly the door it's built for. The L-SG100 self-attaching security grille kit is made for 1-3/4 inch thick doors held to the door industry tolerance of +/- 1/16 inch. If your leaf is a 1-3/8 inch interior door or a thicker custom slab, this kit is the wrong frame depth. Glass thickness is variable, so you aren't locked to one lite thickness, but the door thickness is a single value.
2) Is the NGP 10 x 10 security grille lite kit fire rated, and what do I have to install with it to keep the rating?
Fire rated up to 90 minutes, but only when it's installed with the required GT-316 glazing tape. The tape is part of the rated assembly, not an accessory, so order it with the kit. Substitute a different tape or skip it and the 90 minute rating no longer applies to the opening.
3) What size opening does the NGP L-SG100 10X10 lite kit fit?
It frames a 10 x 10 inch glazing opening, which is the standard small vision lite cut used on stair and corridor doors. The 10 x 10 is a fixed size on this kit, so the door's lite cutout has to already be prepped at that dimension. Larger vision panels need a different size of the same L-SG100 kit, not a modification of this one.
4) What does "self-attaching" mean on an NGP lite kit, and do I need separate glazing beads or through-bolts?
Self-attaching means the two halves of the frame fasten to each other through the door, so there's no separate glazing bead or applied stop to source. The kit comes with counter-sunk screw holes and #6 Phillips truss head screws for flush mounting. For a locksmith or GC on a retrofit, that's the appeal: prep the lite cut, set the grille frame, drive the screws. Torx security screws are available if the door is in a space where you don't want the fasteners backed out with a common driver.
5) How much security does the grille on the NGP L-SG100 actually add over a plain lite kit?
The difference is a welded steel grille, not just a frame around glass. The L-SG100 carries a 16 gauge steel grille on a 3/4 x 3/4 inch pattern, welded on both sides of the opening, inside an 18 gauge cold rolled steel frame. A standard lite kit trims the glass and nothing more. If the concern is someone breaking the vision panel to reach through for a thumbturn or a panic bar, the grille is the part doing that work.
6) What finish does the NGP L-SG100 security grille kit ship in, and can I get it to match painted doors?
Standard finish is GPZ gray primer powder coat, which is a paint-ready surface rather than a final color. If you're matching a door fleet, plan on field painting or order one of the optional color finishes. For corrosive or wash-down locations, galvanneal and zinc electro-plating are offered as additional protective coatings.
7) Can I use the NGP L-SG100 to make one large opening look like two lites?
Yes, false mullion bars are an available option on the L-SG100 kit. They divide the visual opening without cutting a second lite in the door, which is how you match a grille-and-mullion look across doors that were prepped with a single cutout. It's an order-time option, so specify it with the kit rather than adding it later.
8) Is the NGP L-SG100 grille kit suitable for a hospital, school, or detention-type door, or is it a residential product?
It's a commercial product and it's specified that way. The welded 16 gauge grille and 90 minute fire rating put it on rated corridor, stair, and mechanical room doors in schools, healthcare, government and municipal buildings, industrial facilities, and multi-tenant residential. For a facility standardizing vision lites across a rated door fleet, the thing to hold constant is the 10 x 10 lite cut and the 1-3/4 inch door thickness.
9) Are the corners on the NGP security grille lite kit welded or just mitered and screwed together?
Mitered, welded, and backed with welded reinforcing clips at each corner. That matters on a fire rated door more than it sounds: a screwed corner can rack and open up, and the frame has to hold its shape to keep the glazing captured. On high-traffic openings in schools or multi-family corridors, that welded corner is the part that keeps the kit from loosening over years of door slams.
