NGP L-VGLF-MD – Frequently Asked Questions

1) How big a cutout do I need for a 9 x 9 security grille lite kit, and how much glass actually shows?
The L-VGLF-MD frame is 9 x 9 inches overall with a 6 x 6 inch exposed glass area. The frame covers the difference between the two, so plan the door prep around the 9 x 9 outside dimension and expect a 6 x 6 view opening once the grille and frame are on.
2) Is the vision panel in this NGP kit glass or polycarbonate?
Polycarbonate. The security lite kit glazes with 1/2 inch thick high impact polycarbonate plastic rather than glass, and it sits behind a 16 Ga. steel grille with 3/4 x 3/4 inch openings. That combination is what you specify where a plain glass lite would get broken out.
3) Can someone unscrew this lite kit from the corridor side of the door?
There are no exposed fasteners on the outside of the door. The L-VGLF-MD mounts with concealed fastening, so the secure face gives a would-be tamperer nothing to turn. For higher-risk openings, Torx security screws are an available option on the kit.
4) How do you clean or service the glazing behind the steel grille?
The grille side is an 18 Ga. steel hinged panel. Swing it open to reach the polycarbonate for cleaning or replacement, then close it and the opening is secure again. That is the practical difference from a fixed-grille kit, where servicing the lite means pulling the whole frame.
5) What finish does the NGP L-VGLF-MD come in, and can I get it painted to match my doors?
Standard is a gray primer (GPZ) powder coat, which is meant to be finish painted on site to match the door. If you would rather have it come coated, optional powder coat colors are offered, and zinc electro-plating is available where corrosion is the concern.
6) Is a security grille lite kit the right choice, or should I just use a standard vision lite frame?
Pick the security grille version when the opening takes abuse or the room behind it needs to stay closed: detention-style corridors, mechanical and storage rooms, school and healthcare back-of-house, warehouse doors. The L-VGLF-MD gives you a small 6 x 6 inch view with 1/2 inch polycarbonate and a 16 Ga. steel grille over it. A plain lite frame is the better call when you want daylight and sightlines rather than resistance, since the grille and the small view opening cut visibility on purpose.
7) How heavy-duty is the frame on this NGP lite kit?
The frame is 18 Ga. cold rolled steel with mitered, welded corners, so it arrives as one rigid unit rather than a snap-together extrusion that can be racked apart at the joints. The hinged grille panel is the same 18 Ga. steel, with the grille itself a heavier 16 Ga.
8) Can I standardize the same NGP security lite kit across a whole building of doors?
The L-VGLF-MD is a single commercial-grade model, one size at 9 x 9 inches for 1-3/4 inch doors, so every opening you spec it on gets identical prep, identical glazing, and identical replacement parts. That is the point of it for a facility that wants one lite kit on the shelf instead of five.
