Schlage Commercial ND Series Spring Latch

Two backsets are offered on the ND Series spring latch: 2-3/4 inch (part 13-248) and 3-3/4 inch (part 14-010). Measure from the edge of the door to the center of the bore hole. 2-3/4 inch is the standard commercial backset, and 3-3/4 inch is used on wider stiles where the lever has to sit further off the door edge. Both share the same 1-1/8 x 2-1/4 inch square corner faceplate, so the door edge prep does not change between them.

Both. The ND Series latch is adjustable for flat or beveled edge doors, so one part covers a square-edge hollow metal door and a beveled wood door without ordering a different latch. That matters on a mixed building where the openings were not all hung the same way.

Yes. The ND Series spring latch is sold as a replacement part and is compatible with the lock trim, so you pull the chassis, swap the latch, and reuse the existing lever, rose, and cylinder. Match the backset you already have (2-3/4 or 3-3/4 inch) and the faceplate corner style, and the door prep stays as-is.

They are not the same. A spring latch has a plain bevelled latchbolt that retracts on the strike, which is what the ND Series part here is. A deadlatch adds a small auxiliary plunger alongside the bolt that blocks the latch from being carded or shimmed when the door is closed. On an exterior or perimeter door, spec a deadlatch, such as the Dexter Grade 1 deadlatch for the C1000 Series, rather than a plain spring latch. Interior office, classroom, and passage openings are where the spring latch belongs.

No. The ND Series spring latch is made in 2-3/4 inch and 3-3/4 inch backsets only, and a latch is not adjustable across backsets, so a 2-3/8 inch bore leaves the tailpiece short of the chassis. For a 2-3/8 inch opening, the Deltana G1RLE238 covers entry function and the G1RLP238 covers passage/privacy, both Grade 1 at that backset.

The Schlage ND Series spring latch is built in a 2-3/4 inch backset (13-248) and a 3-3/4 inch backset (14-010), both with a square corner 1-1/8 by 2-1/4 inch faceplate, so neither drops into a 2-3/8 inch bore. For that backset, the Deltana G1RLE238 is a Grade 1 regular latch with an entry function, and the Deltana G1RLP238 is the Grade 1 regular latch in passage/privacy. Pick the entry or the passage/privacy version to match the function of the lock already on the door.

Square corner, on both backsets. The faceplate is 1-1/8 x 2-1/4 inches with square corners, which suits a routed square mortise in the door edge. If the existing latch in your door has rounded corners from a router prep, a square plate will leave gaps at the corners unless you square the mortise out with a chisel.

No. The Dexter Grade 1 Deadlatch is built for the Dexter C1000 Series and is a deadlatch, meaning it carries a deadlocking plunger alongside the latchbolt. The Schlage ND Series part is a spring latch, adjustable for flat or beveled edge doors and matched to ND Series lock trim. They are different latch types tied to different chassis, so treat the Dexter part as the C1000 service part and the 13-248 or 14-010 as the ND Series service part.

The Schlage ND Series spring latch is a replacement latch only, made of stainless steel, sold in fixed 2-3/4 inch and 3-3/4 inch backsets and installed behind existing ND Series lock trim. The Lockey M230 is a complete mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset and a 1-1/8 to 2 inch door thickness range, so it brings its own trim and access method rather than servicing a lock already on the door. Order the Schlage part to repair an ND Series lockset; order the M230 when the whole opening is being converted to pushbutton entry.

They serve different openings. The Accentra YSSL10 is a security sidelite auxiliary latch with an ADA compliant thumbturn, fire rated, and built for a 1-3/4 inch door, so it secures a sidelite panel rather than replacing the latch inside a cylindrical lockset. The Schlage ND Series spring latch is a commercial replacement latch that seats behind ND Series lock trim in a 2-3/4 or 3-3/4 inch backset prep. A sidelite gets the YSSL10; the active leaf lockset gets the Schlage latch.

At 2-3/4 inch the Deltana G1RLE275 covers entry doors and the Deltana G1RLP275 covers passage and privacy doors, both Grade 1 regular latches; at 2-3/8 inch the same split is the G1RLE238 for entry and the G1RLP238 for passage/privacy. Where the doors already carry Schlage ND Series lock trim, the 13-248 spring latch covers the 2-3/4 inch preps and the 14-010 covers 3-3/4 inch preps, and both are adjustable for flat or beveled edge doors so one part number serves either door edge.

Stainless steel construction, which is why it is used on commercial ND Series openings rather than residential trim. Stainless resists the corrosion you get in coastal, kitchen, and washdown areas and does not gall the way a plated pot-metal latch does under constant cycling. For a school corridor, a hospital wing, or an apartment building common door, this is the latch that matches the rest of the ND hardware.

Nine finishes, and both backsets are offered in all of them: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. On a standing order across a building, 626 satin chrome is the usual commercial default. Only the faceplate shows once the door is closed, so match it to the strike plate rather than the lever if the two differ.

Genuine, certified Schlage parts. On an ND Series opening that matters more than it sounds: an aftermarket latch that is a hair off on tailpiece length or faceplate thickness will bind against the chassis or sit proud of the door edge. Buying the factory latch keeps the lockset performing the way it was specified.
