BEST 4903A 630 RHR – Frequently Asked Questions

1) Will BEST 4900 Series night latch lever trim work on my exit device, or does it only fit certain models?
The 4900 Series lever trim is built for 2000 Series exit devices. It is not a universal exit trim, so if the device on the door is another series or another brand, this is the wrong trim. For a different device family you would be looking at trim matched to that device, for example the Sargent 704ET night latch lever trim for their 700 Series or the Corbin Russwin VT957ET nightlatch escutcheon for the ED5000 Series.
2) Will BEST 4900 lever trim fit a narrow stile aluminum storefront door?
No. The 4900 Series trim is a wide stile design, so it needs the stile width of a hollow metal or wood door or a wide stile aluminum door. On a narrow stile storefront you need trim built for that profile; this escutcheon will not land on the stile.
3) Do I have to order BEST 4900 trim handed, or can it be reversed in the field?
Both. The trim is ordered as LHR or RHR, and it is also field reversible, so a lever can be changed on site if the opening turns out to be the other hand. Note that exit device trim is called out in reverse bevel terms (left hand reverse and right hand reverse) because the door swings out under a push bar.
4) What do I need to specify when ordering BEST 4900 Series night latch trim?
Four things: handing (LHR or RHR), lever design (A, B, C, D, or a K knob), finish, and trim type. Trim type is where the device mounting is decided: standard trim, M for mortise trim, R for retrofit trim, or RM for retrofit mortise. Getting the trim type wrong is the most common ordering mistake, since mortise trim carries the mortise device hub and retrofit trim is for replacing existing trim.
5) What trim gives a classroom or storeroom lock function instead of night latch?
Storeroom and classroom trims keep the lever locked or unlocked by key rather than key-retract-only. Design Hardware KIL storeroom function trim fits 1000 and 2000 Series exit devices with a Schlage C keyway and flat lever, Pamex E9000 is a Grade 1 storeroom L3 lever heavy duty trim for doors 1-3/8 to 2 inch, and Tell EDELT80 is a storeroom function escutcheon lever trim. For classroom, Falcon 510L is a heavy duty classroom trim in the 24/25 Series and Accentra 446F is a Grade 1 classroom Augusta lever trim. The BEST 4900 Series is night latch function only.
6) Can an electrified exit trim be used in place of a mechanical night latch lever trim?
Only where the opening is being put on access control. Command Access ET15, ET25 and ET26 are electrified exit trims with 12V/24V operation and fail safe/fail secure options, the ET26 built Grade 1 and field reversible, and the 230L is an electrified version of the Von Duprin 230L trim for V96, 36 and 23 Series devices. Von Duprin E360L-BE-03 is a Grade 1 electric passage trim, fail safe, for 33/35A Series. Those require power to the door; the BEST 4900 Series is a mechanical key-operated night latch trim with no wiring.
7) What is the closest equivalent to a BEST 4900 night latch lever trim from another manufacturer?
The Sargent 704ET is the nearest match in function and behavior: it is a night latch lever exit device trim with field reversible operation, Grade 1, heavy duty. The BEST 4900 Series is also a night latch lever trim with field reversibility. Sargent also builds the 704-ETL, a night latch lever trim with key retract function in the PE Series, and the 744 in the 8700/8900 Series, a Grade 1 night latch trim with freewheeling operation where the key retracts the latch. The BEST 4900 mounts to 2000 Series exit devices, so confirm the device family before substituting.
8) If a door does not need a lever on the outside, what can be used instead of a keyed lever trim?
A pull trim covers that opening. The Design Hardware 2P-03NL is a Grade 1 pull trim with a cylinder hole in night latch function for 1000R and 2000R exit devices, and the Tell EDPT is an exit device pull trim with a cylinder hole, less cylinder, for doors 1-3/8 to 1-3/4 inch thick. The Dexter ED1500T-PULL-NC is a nightlatch function trim with a raised lip pull plate. All keep key-retract entry but drop the lever, where the BEST 4900 Series carries an operating lever in A, B, C or D designs plus a K knob.
9) What trim should be used if the outside lever needs to stay unlocked instead of key-only entry?
Night latch trim retracts the latch by key only, which is the BEST 4900 Series function. For an opening where the outside lever always operates, a passage trim is the correct part: Arrow SRX01 is a passage function Sierra lever with rose for ED910, S1150 and S1250 devices, Corbin Russwin 3310AET is passage function trim for ED300 Series rim, surface vertical rod and mortise devices, and the x910ET is passage function heavy-duty trim for the ED5200S, ED5200, ED5400 and ED5800 Series.
10) What looks like a night latch lever trim but will not let a key retract the latch?
Dummy and blank escutcheon trims. The Von Duprin 230DT is a dummy trim for 22 Series devices with a 10 gauge steel escutcheon, the 210K-BE is a knob with blank escutcheon for 22 Series, Detex 02BN is a dummy S-lever trim with blank escutcheon for Value Series devices, Dexter ED1500T-DUMM-PULL is a dummy function trim with handle pull plate, and Falcon 212L is a blank escutcheon lever trim for 20 Series. Those are pull-only on the outside. The BEST 4900 Series is night latch function with a recessed cylinder, so the key retracts the latch.
11) What should be checked before substituting a different brand's trim on a 2000 Series exit device?
The device family is the gate. The BEST 4900 Series is built for 2000 Series exit devices and comes in standard, M mortise, R retrofit and RM retrofit mortise configurations. Peer trims are tied to their own devices: Corbin Russwin x810ET to the ED4000 Series, VT957ET to the ED5000 Series, Command Access ET25 to the ET25 Series and Von Duprin 230DT to 22 Series. Match the trim to the chassis it drives, then match handing, lever design and finish.
12) I am replacing existing exit device trim, not doing a new install. Is there a version for that?
Yes. The 4900 Series is offered in an R retrofit trim and an RM retrofit mortise version alongside standard and M mortise trim, so a change-out on an existing 2000 Series device is an ordering option rather than a re-prep.
13) Does BEST 4900 trim come with a cylinder?
The trim uses a recessed cylinder design, and the cylinder is a separate specification. Plan on supplying a rim or mortise cylinder to match the trim type ordered and keyed into your existing system, since a night latch function is worthless without the key that retracts the latch.
14) Will this lever hold up on a high traffic school or apartment exterior door?
It is built for abuse: extra strength overload springs and cast stainless steel internal components, with a lever that returns to home position on its own so nobody has to reset it after it gets yanked. That combination is what keeps a night latch lever working on doors that see constant public use.
15) What other wide stile night latch lever trims use an escutcheon like the BEST 4900?
The Dorma YR03R is a wide stile exit device lever trim with an escutcheon and R lever, night latch function, supplied less cylinder. The Corbin Russwin VT957ET is a nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices. The BEST 4900 Series is a wide stile lever trim with a recessed cylinder design and cast stainless steel internal components. All three are keyed night latch trims, so match the trim to the exit device family it is being hung on.
16) Is the Von Duprin 110MD-NL an alternative to a night latch lever trim?
It solves a different part of the opening. The 110MD-NL is a Grade 1 heavy duty night latch cylinder assembly for metal and wood doors, used with 22, 55 and 98/99 exit trim, so it provides the keyed retract without an outside lever or escutcheon plate. The BEST 4900 Series is a full lever trim for 2000 Series devices with a lever in A, B, C or D design or a K knob and a recessed cylinder in the plate. Choose the cylinder assembly when the door only needs key entry and no gripping surface.
17) What replaces a keyed exit trim when the building wants to stop issuing keys?
Pushbutton trim removes the cylinder from the equation. The Dormakaba E-Plex 201U is an electronic pushbutton exit trim built for wide stile doors, the PowerPlex P201U works on rim, mortise and surface vertical rod devices, and the E-Plex 5067 is a mechanical pushbutton mortise lock, also wide stile. The BEST 4900 Series is a wide stile trim that entered by key through a recessed cylinder, so the door prep and stile width are comparable but the credential is not.
18) Which night latch trims are field reversible for handing?
The BEST 4900 Series is field reversible and is stocked in LHR and RHR handings. The Sargent 704ET is a night latch lever exit device trim with field reversible operation, and the Command Access ET26 electrified trim is Grade 1 with a field reversible design. Field reversibility matters when a fleet of openings mixes handings and the crew wants one part number on the truck.
19) What is the difference between a lever/rose exit trim and an escutcheon lever trim like the BEST 4900?
A rose trim mounts the lever on a small round plate; an escutcheon covers a tall plate area on the door face. Marks USA M195F is a storeroom function lever/rose exit device trim with spring loaded roses for the M9900 touchbar, and M195N is a lever/rose trim in the M195N Series. The BEST 4900 Series is a wide stile lever trim with a recessed cylinder in the trim. Rose trim leaves prior escutcheon cutouts exposed, so on a retrofit check what the removed trim covered.
20) Is a thumbpiece trim an option instead of a lever trim on an exit device?
Yes, where a gripping thumbpiece suits the door better than a lever. Tell EDTHP53 is a thumbpiece exit device trim in keyed entry function for doors 1-3/8 to 1-3/4 inch, and Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom trim combining a thumbpiece, pull plate and cylinder, supplied less cylinder. The BEST 4900 Series uses a lever that returns automatically to the home position with no resetting required, which is the operating difference to weigh for high traffic openings.
21) What finishes does the BEST 4900 lever trim come in, and can I match the other doors in my building?
Eight standard architectural finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 622 matte black, 625 bright chrome, 630 satin stainless steel, and 690 statuary dark bronze. Most commercial buildings standardize on 630 satin stainless or 626 style chrome tones, so 630 is the usual match for existing exit hardware.
22) Can I get a knob instead of a lever on the BEST 4900 night latch trim?
Yes, a K knob is one of the handle options alongside the A, B, C, and D lever designs. Bear in mind that in most jurisdictions accessible egress and entry hardware has to be operable without tight grasping or twisting, which is why levers are the default on commercial openings and knobs get used on service doors.
23) What lighter duty exit trim is there compared with a heavy duty night latch lever trim?
Falcon lists two medium duty trims: the 179L lever control trim in the 1790 Series, classroom function, and the 212L escutcheon lever trim for 20 Series devices with shear pin protection. Heavier options include Falcon 510L heavy duty classroom trim for 24/25 Series and Sargent 704ET heavy duty Grade 1 night latch trim. The BEST 4900 Series is built with extra strength overload springs and cast stainless steel internal components for vandal resistance in high traffic openings.
24) Which exit trims cover both night latch entry and a matching escutcheon appearance across a building?
For a standardized look on a mixed set of doors, Accentra offers the 121NL nightlatch trim, the 441F night latch keyed lever with Augusta design, and the 426F Augusta lever escutcheon trim for 6000 and 1800 Series, so the same lever design carries across functions. The BEST 4900 Series holds appearance across a fleet a different way, with eight finishes from 605 bright brass through 630 satin stainless and 690 statuary dark bronze on one trim family.
