Tell Storefront Deadlatch Mortise Lock, Non-Handed, Aluminum & Duranodic

The Tell storefront deadlatch comes in two backsets, 31/32 inch and 1-1/8 inch. Measure from the edge of the aluminum stile to the center of the cylinder hole on the existing lock and match it. Getting this wrong is the usual reason a storefront lock won't drop into the prep, since the two sizes are only about an eighth of an inch apart.

No handing to specify. The Tell storefront deadlatch mortise lock is non-handed, so one part covers left and right hand aluminum doors and inswing or outswing.

It accepts any standard 1-5/32 inch mortise cylinder or a thumbturn, provided you use the proper cylinder cam. The cylinder is the separate piece you specify, so a keyed-alike storefront program can keep whatever keyway is already running on the building and just add cylinders to match.

When the door closes, the auxiliary bolt is pushed in against the strike, and in the locked position that deadlocks the latchbolt. Once deadlocked, the latch can't be loided back with a knife or shim tool. It's the reason a deadlatch is used on glass-front entries instead of a plain spring latch.

No. This is a storefront deadlatch built for narrow aluminum stile doors, with 31/32 inch and 1-1/8 inch backsets. A hollow metal or wood opening takes a standard mortise lock on a 2-3/4 inch backset, such as the Sargent 7925 or a Corbin Russwin ML2003 for a 1-3/4 inch door.

The Tell storefront deadlatch mortise lock is offered in 31/32 inch and 1-1/8 inch backsets, which are the two common aluminum storefront stile dimensions. If neither fits, the Kaba Ilco 185 Series mortise lock is a non-handed mortise deadbolt-function unit, so it covers a keyed aluminum-door application without handing selection. The Ilco BR Series is a different approach entirely - a bottom rail lock for all-glass doors rather than a stile-mounted deadlatch.

They are not interchangeable. The Tell storefront deadlatch mortise lock is a narrow-backset unit built for aluminum and duranodic storefront stiles and takes any standard 1-5/32 inch mortise cylinder or thumbturn with the proper cam. A Grade 1 storeroom lockset such as the Accentra 8805FL with Arcadia lever or the Cal-Royal NM8080, which is listed for 1-3/4 inch doors, uses a full-size mortise case and lever trim intended for a hollow metal or wood door, not a narrow stile.

It's purely mechanical, no wiring or power. If you want keypad or credential control on an aluminum storefront, the Alarm Lock DL1300NW Trilogy Networx wireless mortise lock is made for Adams Rite style deadlatch preps instead.

This one is a deadlatch: a spring latch with an auxiliary deadlocking bolt, so the door latches on closing. If you want a true hookbolt or deadbolt style mortise lock with no handing for a narrow stile door, look at the Kaba Ilco 185 Series, which is a non-handed deadbolt function mortise lock. For a glass door with a bottom rail, the Ilco BR Series bottom rail lock is the one that fits.

Yes. The lock takes a standard 1-5/32 inch mortise cylinder or a thumbturn with the correct cam, so you can run key outside and thumbturn inside for free egress, or cylinder both sides where the occupancy allows it.

The Tell storefront deadlatch mortise lock is a mechanical, non-electronic lock operated by a mortise cylinder or thumbturn. For keypad credentials on a narrow aluminum door, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built with a keypad for Adams Rite style deadlatches, and the Dormakaba E-Plex 2066 electronic pushbutton keyless mortise lock is listed for wide stile. Those add code management the mechanical Tell unit does not provide.

The Tell unit is a deadlatch: the latchbolt retracts for normal operation and, when locked, an auxiliary bolt is depressed against the strike to deadlock the latchbolt and resist jimmying with knife-like tools. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which throws a bolt only and needs a separate latch or push-pull for day operation. The Kaba Ilco 185 Series is likewise deadbolt function.

No. The Schlage PM010 is a non-keyed Grade 1 passage latch mortise lock for 1-3/4 inch doors, so it never locks and will not take a cylinder. The Tell storefront deadlatch mortise lock is keyed through any standard 1-5/32 inch mortise cylinder or thumbturn and is sized for aluminum and duranodic storefront stiles.

The Tell storefront deadlatch mortise lock is a storefront-stile unit without a classroom function. For classroom-function openings on 1-3/4 inch doors, the Corbin Russwin ML2003 Grade 1 mortise classroom lockset and the Cal-Royal NM8070 Grade 1 classroom mortise lockset with auxiliary deadlatch both carry that function, and the TownSteel FME-2000 adds RFID credentials in a Grade 1 classroom mortise lockset.

Aluminum and duranodic, which are the two standard storefront colors, so it blends with clear anodized and dark bronze frames without any extra trim.
