NGP 814SS-4x36 – Frequently Asked Questions

1) What is the NGP 814 cover plate actually used for?
The NGP 814 is a flat aluminum cover plate with a 1/4 inch profile, used to bridge and conceal a gap in the floor rather than to seal a door bottom. Typical work is expansion joint covers, floor transitions between two finishes in commercial and industrial buildings, and doorway transitions in schools, healthcare, warehouses and multi-tenant residential. It is a commercial-duty part, and it ships with #10 x 1-1/2 inch zinc plated wood screws so it can go down as soon as it lands.
2) Will the NGP 814 cover plate work over a wide expansion joint?
It covers a lot of ground. The 814 is made from 3 inches minimum up to 48 inches wide, in lengths to 144 inches, so a single piece can span a joint far wider than a standard threshold covers. Measure the open joint, then add the bearing you want on each side of it, and order to that total width. Anything past 144 inches in run has to be broken into multiple pieces.
3) What sizes does the NGP 814 come in?
Stock cut sizes run 4 x 36 inches, 4 x 36-1/2, 4 x 72-1/2, 8 x 48, 8 x 72, 9-1/2 x 43-1/2 and 11-1/2 x 47-1/2 inches. Outside those, the 814 is made to order anywhere from 3 to 48 inches wide and up to 144 inches long, with optional custom drilling to your hole pattern.
4) Is the Pemko 272 threshold a substitute for the NGP 814 cover plate?
They share a 1/4 inch height but do different jobs. The Pemko 272 is an ADA compliant flat saddle threshold in heavy-duty aluminum at 1/4 inch by 6 inches, a fixed 6 inch width meant to sit under the door. The NGP 814 is a 1/4 inch profile cover plate in milled aluminum alloy 3003 H14 that is made to order in widths from 3 inches to 48 inches and lengths to 144 inches, which is what lets it cover expansion joints and wide floor transitions. For a standard door saddle at 6 inches wide, the 272 is the direct item; for coverage wider than a saddle, the 814 is the one that reaches.
5) What is a good alternative to the NGP 814 cover plate when the opening needs a fire rated threshold?
The NGP 814 is a 1/4 inch profile milled aluminum cover plate in the Offset Threshold Series, used to cover floor transitions and expansion joints rather than to serve as a rated door threshold. When the opening calls for a fire rated saddle, the Cal-Royal CR3700 saddle threshold series carries a 3-hour positive pressure fire rating, and the Cal-Royal CR2000 saddle threshold series is offered with a fire rated and ADA compliant design. Both are saddle thresholds set at the door, whereas the 814 is a flat cover plate that can run up to 144 inches long and from 3 to 48 inches wide.
6) I need to cover a wide expansion joint in a warehouse floor. Will a standard saddle threshold work?
A standard saddle is sized for a door opening, not a joint. The Pemko 272 flat saddle threshold is 1/4 inch by 6 inches, and the Cal-Royal CR2000 and CR3700 are saddle threshold series set at the door. The NGP 814 cover plate is built for the wider run: 1/4 inch profile, minimum width 3 inches, maximum width 48 inches, lengths to 144 inches, rolled aluminum alloy 3003 with H14 hardness, beveled edges, and #10 x 1-1/2 inch zinc plated wood screws included. It is the item for expansion joint covers and industrial floor transitions.
7) Is the NGP 814 strong enough for forklift and pallet jack traffic in a warehouse?
The 814 is rolled from 3003 aluminum alloy at H14 temper, which is a work-hardened half-hard temper rather than annealed stock, and the rolled process is what NGP uses on its extra-width, extra-strength plates. It is specified for commercial and industrial floor transitions including warehouse and distribution centers. For rolling loads, the more important detail is support: a cover plate is only as stiff as what is under it, so bed it on solid substrate across the full width and fasten on the stated screw pattern.
8) I need to standardize floor transitions across a whole building. Can I order NGP 814 plates in matching custom sizes?
Yes, the 814 is a made to order part. You give the width and length within 3 to 48 inches wide and up to 144 inches long, and custom drilling is available to your specification, so a facility can run one profile height and one finish across every opening with each piece cut to its own transition. Standard cut sizes exist too, which is usually the cheaper path anywhere the run happens to match 4, 8, 9-1/2 or 11-1/2 inch widths.
9) What does the milled finish on the NGP 814 look like, and will it be scratched when it arrives?
Milled is mill finish aluminum, the natural silver-grey of the alloy with no anodizing or paint over it. NGP applies a protective PVC film during manufacturing that stays on through shipping and installation, so the face is covered until you peel it after the plate is fastened down. Leave the film on while you cut and drill.
10) Can I cut an NGP 814 cover plate to length on site?
Aluminum 3003 at H14 cuts cleanly with a carbide blade, so field trimming a long piece is routine. The thing to know before you cut is that the beveled edge is rolled in along the length; a fresh cut end is square, not beveled. If a beveled end matters at your transition, order the plate made to size instead, since the 814 is made to order anywhere within the 3 to 48 inch width and 144 inch length range.
