Dorma ZT08 Grade 1 Exit Trim, Z Escutcheon, T Lever, Classroom, 96/97/9800

The ZT08 Z escutcheon trim with T lever is built for the Dorma 96, 97 and 9800 devices, and it works across rim, surface vertical rod and concealed vertical rod configurations in those families. So the same trim part covers a single door on a rim device and a pair of doors on vertical rod devices; the trim itself does not change with the latching type.

Handing matters here. The ZT08 is ordered as either left hand or right hand, so determine the hand of the door before you order rather than assuming the trim is field reversible. Stand outside the door, on the side the trim mounts: if the hinges are on your left it is left hand, on your right it is right hand.

Both ways are orderable. You can take the ZT08 with a mortise cylinder in a 6-pin Schlage C keyway, or less cylinder if you are keying it into an existing system with your own cylinders. Locksmiths and integrators standardizing a building usually take the less cylinder version and pin it to the master; a single opening replacement is simpler with the cylinder supplied.

Yes, when ordered with the cylinder. Keying is a required selection: keyed different is the standard, keyed alike is available for running multiple openings on one key, and there is a no-keying choice that pairs with the less cylinder version. If you need a specific bitting, master key level or a keyway other than the conventional Schlage C, that goes in the special cylinder and keying request field on the order.

Classroom, like the ZT08, lets the outside lever be keyed into a locked or unlocked state, so the door can be left free during occupied hours. Storeroom keeps the outside lever locked at all times and the key only retracts the latch for entry, which is what you want on a mechanical room or supply closet: Design Hardware's KIL storeroom trim and the Pamex E9000 with the L3 lever are both storeroom function. Nightlatch trim is key retract only with no lever holding function, such as the Sargent 704ET or the Accentra 121NL. Pick classroom when someone needs to change the door's state without a tool, storeroom when they never should.

No. The ZT08 is built to the Dorma 96, 97 and 9800 devices and trim is not interchangeable across manufacturers, since the escutcheon prep and the spindle or tailpiece engagement differ by device family. For a Von Duprin 22 Series opening use trim from the 210 or 230 families, such as the 230DT dummy trim or the 210K-BE. For Sargent, the 704ET covers the 700 Series and the 744 covers 8700 and 8900 surface vertical rod and mortise devices. Corbin Russwin trim is likewise series specific, x910ET for ED5200/ED5400/ED5800 and x810ET for ED4000.

The Dorma ZT08 is a keyed classroom trim, so it only earns its cost where the outside lever has to be locked and unlocked by key. Where the outside lever should always retract the latch, use a passage trim: the Corbin Russwin 3310AET is a passage function trim for ED3000 Grade 1 devices, the x810ET is passage for ED4000, the x910ET is passage for the ED5200S, ED5200, ED5400 and ED5800 series, and the Arrow SRX01 is a passage function Sierra lever with rose for ED910, S1150 and S1250 devices. Where the outside needs to be pull only with no lever action, the BEST 4900 Series and 2900 Series are exit only lever trims for 2000 Series devices, wide stile and narrow stile respectively.

Classroom function on the Dorma ZT08 means entrance by lever only when released by key, with the key removable only when locked, so the lever can be left unlocked. If you want the lever always locked from outside, look at storeroom trims. The Tell EDELT80 is an exit device escutcheon lever trim in storeroom function for doors 1-3/8 inch to 1-3/4 inch thick. The Pamex E9000 is a Grade 1 storeroom heavy duty exit trim with an L3 lever, for doors 1-3/8 inch to 2 inch. The Design Hardware KIL storeroom trim uses a flat lever with a Schlage C keyway and fits 1000 and 2000 Series devices, and the Marks USA M195F is a storeroom lever and rose trim for the M9900 touchbar.

No, and it is the substitution most often made by mistake. On the Dorma ZT08 the outside lever retracts the latch once the key has released it, and the key comes out only when locked, so the lever can be left free for the school day. A nightlatch trim keeps the outside secure at all times and the key alone retracts the latch. The Sargent 704ET and 704-ETL are night latch lever trims, Grade 1 heavy duty, for the 700 and PE Series, the Sargent 744 is a Grade 1 freewheeling night latch trim where the key retracts the latch on 8700 and 8900 surface vertical rod and mortise devices, the Corbin Russwin VT957ET is a nightlatch escutcheon trim for ED5000 Series, and the Accentra 121NL and AU-441F are nightlatch trims. Choose nightlatch only if you never want the outside lever to be left unlocked.

The Dorma ZT08 is built for rim, surface vertical rod and concealed vertical rod devices in the 96, 97 and 9800 families. For a mortise exit device, the Sargent 744 is a Grade 1 freewheeling trim that retracts the latch by key and is made for surface vertical rod and mortise 8700 and 8900 Series devices. The Corbin Russwin x810ET covers SecureBolt, rim, surface and concealed vertical rod on ED4000 Grade 1 devices in passage function. Exit trim is matched to the device chassis, so confirm the device series before you order.

Mechanically these are alternatives on the same devices, but they behave differently for accessibility. The Dorma ZT08 is a lever trim, which is what ADA compliant openings normally require on the accessible route. The Von Duprin 210K-BE is a Grade 1 heavy duty knob trim with blank escutcheon for 22 Series devices. The Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom trim using a thumbpiece with pull plate and cylinder, less cylinder, and the Tell EDTHP53 is a thumbpiece trim in entry function for 1-3/8 inch to 1-3/4 inch doors. Substitute a knob or thumbpiece only where the opening does not require lever operation.

Both paths are covered. The trim accepts a conventional mortise cylinder in the Schlage C keyway, which is what most North American buildings key to, and a cylinder adaptor is provided to suit a Euro profile cylinder for openings keyed on that system. Decide which before ordering, because the keying selection on the order is tied to it.

Yes. The ZT08 is listed for rim, surface vertical rod and concealed vertical rod devices in the Dorma 96, 97 and 9800 families, so the same trim serves a single rim door and either leaf of a pair running vertical rods. You order one trim per active leaf that needs outside key control.

Both are keyed lever trims, but the outside behavior differs. On the Dorma ZT08, classroom function, the lever gives entrance only when released by key and the key comes out only when the trim is locked. Entry function trims are keyed with the lever operating as an entry set: the Design Hardware KIL entry and LE08 are Grade 1 entry function trims with flat levers, the LE08 with an escutcheon for 1000R and 2000R devices, the Tell EDELT53 is a keyed entry escutcheon lever trim for 1-3/8 inch to 1-3/4 inch doors, and the Delaney 500L comes in CT, MD and SD lever styles in entrance function.

The Dorma ZT08 is mechanically keyed, so locking and unlocking the outside lever happens at the door with a key. If you want that control from an access control system, the electrified trims in the set do it: Command Access ET15, ET25 and ET26 all run 12V or 24V with fail safe and fail secure options, and the ET26 is Grade 1 and field reversible. The Command Access 230L is the electrified version of the Von Duprin 230L for V96, 36 and 23 Series devices. Falcon also offers the 510L-FSA/FSE, an electrified heavy duty lever trim for 25 Series devices, and Von Duprin the E360L-BE-03, a Grade 1 electric passage trim with an 03 lever, fail safe, for 33 and 35A Series.

Yes. The Dorma ZT08 carries a cylinder and a working classroom lever, which you do not need if the outside is pull only. Simpler options: the Tell exit device pull trim with cylinder hole, less cylinder, fits 1-3/8 inch to 1-3/4 inch doors; the Design Hardware 2P-03NL pull trim has a cylinder hole in night latch form for 1000R and 2000R devices; the Dexter ED1500T dummy trim uses a handle pull plate and the ED1500T nightlatch trim a raised lip pull plate, both Grade 1. For a non-functioning lever appearance, the Detex 02BN is a dummy S-lever with blank escutcheon and the Von Duprin 230DT a dummy trim on a 10 gauge steel escutcheon for 22 Series.

Both are classroom function lever trims, but they are built to different duty levels. The Dorma ZT08 is a Grade 1 trim. The Falcon 179L is a classroom function lever control trim for 1790 Series devices rated medium duty, while the Falcon 510L is the classroom function trim rated heavy duty for 24/25 Series devices. On a corridor or gymnasium door taking constant cycles, the heavy duty classroom trims are the closer match to the ZT08.

The Dorma ZT08 uses a Z escutcheon, a full plate behind the lever. If the door face or an existing prep favors a rose, the Marks USA M195F is a storeroom function lever and rose trim with spring loaded roses for the M9900 touchbar, the M195N is a lever and rose trim in the M195 Series, and the Arrow SRX01 is a passage function Sierra lever with rose for ED910, S1150 and S1250 devices. Rose trim and escutcheon trim prep the door differently, so a swap between them is not a drop-in on an existing opening.

No. The Dorma ZT08 is a full escutcheon and lever assembly that gives entrance by lever once released by key. The Von Duprin 110MD-NL is a night latch cylinder assembly for metal and wood doors, Grade 1 heavy duty, for 22, 55 and 98/99 devices - it is the cylinder side of a nightlatch arrangement, not a lever trim, so the outside has no lever to grip. It fits where a rim device is retracted by key alone.

The Dorma ZT08 is ordered by hand, left or right, so the hand has to be confirmed before the order. If you would rather stock one part for both hands, the Command Access ET26 electrified trim is Grade 1 and field reversible, and the Sargent 704ET night latch lever trim has field reversible operation. Those are different functions from a keyed classroom trim, so check the function suits the opening before choosing on reversibility alone.
