NGP 427EX424E-36 – Frequently Asked Questions

1) Will the NGP 5X427E x 424E threshold work with my floor closer, or is it made for one brand?
The 5X427E x 424E is fabricated to suit any floor closer. The wider 7 inch section sits over the closer body, and the rest of the run carries the 4 inch wide by 1/2 inch tall saddle profile. Because it is cut and prepped for the closer you are using, you tell NGP which closer is in the floor rather than matching a brand-specific part number.
2) Does the NGP floor closer threshold come with fasteners, or do I need to buy screws separately?
Screws are in the box. NGP supplies #10 x 1-1/2 inch flat head zinc plated wood screws with the threshold, and dark bronze screws ship with the DKB (Dark Bronze) finish so the heads match. If you are anchoring into concrete rather than a wood sub-floor, you will need masonry anchors of your own.
3) What lengths and finishes does the NGP floor closer threshold come in?
Four lengths, 36, 48, 72 and 96 inches, each available in Mill Aluminum or Dark Bronze. The 36 and 48 inch pieces cover single door openings; 72 and 96 inch cover pairs or wide storefront entrances. An optional SIA slip-resistant finish can be added for wet or hazardous areas.
4) How tall is this saddle threshold, and will it be an ADA trip issue at the door?
The saddle section stands 1/2 inch tall over a 4 inch width, which is a low-profile saddle rather than a ramped or panic-height unit. At 1/2 inch it is the flattest part of the assembly other than the floor itself, so it reads as a shallow rise at the opening. The fluted top adds texture for footing and helps water shed off the face.
5) Should I order the plain fluted top or the SIA slip-resistant finish?
The fluted top alone is enough for most interior and covered entrances; the flutes give some traction and let water run off. Go to the optional SIA slip-resistant surface where the opening gets wet or where slip performance is a stated priority, such as a pool deck, a kitchen service door, or an exterior entrance with no canopy. SIA does not change the profile, only the walking surface.
6) I need to cover a pair of doors with a floor closer at each leaf. Which length do I order?
Take the 96 inch length for most pairs; 72 inch covers narrower pairs. One continuous piece across both leaves is preferable to two butted pieces because the 7 inch wide closer section has to land correctly under each closer, and a single run lets the fabricator locate both cutouts off one datum.
7) Which finish should I pick to match the rest of my entrance hardware?
Two choices: Mill Aluminum, which is the raw silver extrusion finish that matches clear anodized storefront and aluminum door frames, and Dark Bronze, which matches bronze anodized storefront, bronze frames and dark door trim. Dark Bronze also ships with matching bronze screws so the fastener heads do not stand out on the walking surface.
