Metallics NP400B – Frequently Asked Questions

1) What size nail plate is the Metallics NP400B, and will it cover a bored stud where I ran cable?
The NP400B nail plate measures 1-1/2 by 2-3/4 inches in 16 gauge steel. That footprint covers a single bore or notch in the face of a stud where cable, tubing, or small conduit passes through. Metallics notes dimensions on nail plates and straps are approximate, so for a wider notch or a gang of cables you want a longer plate or strap rather than butting two of these together.
2) Are Metallics NP400B nail plates Buy American and ARRA compliant for a federal or institutional job?
Yes. The NP400B is flagged Buy American compliant and ARRA compliant, with country of origin the United States. That covers the documentation most government, school district, and federally funded healthcare projects ask for on fasteners and protection hardware.
3) Is 16 gauge steel heavy enough for a nail plate, or do I need something thicker?
16 gauge steel is the common weight for stud protection plates and is what the NP400B is made from. It stops a drywall screw or finish nail from reaching cable or tubing behind the stud face. If your inspector is calling for a specific thickness beyond that, Metallics offers other gauges on request.
4) Can I use these nail plates for plumbing and HVAC lines too, or are they electrical only?
The NP400B is listed for electrical, plumbing, heating, and air conditioning work. Same plate, same job: protecting whatever runs through the stud from fasteners driven into the face. Plumbers use them over PEX and copper stub-outs, HVAC crews over small refrigerant lines and thermostat wiring.
5) How many nail plates come in a box of Metallics NP400B?
They ship 500 to a box, and 500 each is the order minimum, so this is a full-box buy rather than a loose-count item. The box weighs 33.9 lbs. For crews doing production framing or multi-family rough-in that quantity goes fast; for a single service call it is more plate than you need.
6) I need a longer protection plate than 2-3/4 inches for a wide notch. What are my options from Metallics?
The NP400B is the 1-1/2 by 2-3/4 inch size. Metallics states other sizes, gauges, and quantities are available by request, including longer nail straps for notched studs and joists where a short plate will not span the opening. Specify the span you need to cover and the gauge your spec calls for.
7) What is the shipping box size and weight for a 500-count box of NP400B nail plates?
The carton runs 11.5 in long by 11.5 in wide by 10.75 in high and weighs 33.9 lbs. One person can carry it, and it stacks on a shelf or fits in a van bin without repacking.
