Delaney 504L - SD Style Lever Exit Device Exterior Trim - Night Latch Function

Yes. The 504L covers a door thickness range of 1-3/4 inches to 2 inches, so a standard 1-3/4 inch commercial hollow metal door is right in range. It will not work on a 1-3/8 inch door, which is common on older interior openings. If you're trimming a 1-3/8 inch door, the Tell EDELT53 entry trim or EDELT80 storeroom trim cover 1-3/8 to 1-3/4 inches instead.

No patching needed on a stock hollow metal door. The 504L escutcheon is sized to cover a standard 161 cylindrical cutout, so if you're converting a door that previously carried a cylindrical lockset over to an exit device, the trim hides the existing prep.

Standard is a Schlage C 6-pin cylinder. A KW1 5-pin cylinder is the optional alternative, so if the building is keyed Kwikset you can stay on your existing system rather than starting a second key set for one door.

The Delaney 504L SD lever trim runs a night latch function, where the lever is released by key and is otherwise always locked. Direct night latch lever counterparts include the Sargent 704ET night latch lever exit device trim, which is Grade 1 heavy duty and field reversible, the Sargent 704-ETL night latch lever trim with key retract in the PE Series, and the Dorma YR03R wide stile escutcheon lever trim, also night latch function and supplied less cylinder. Match the replacement to the exit device family already on the door, since exit trim is device specific.

The Delaney 504L is mechanical night latch trim keyed with a Schlage C 6-pin cylinder standard, so entry is by key only. For a card reader or remote release you want electrified exit trim: Command Access offers the ET15, ET25 and ET26 series and a 230L to electrify Von Duprin V96/36/23 series, all with 12V/24V operation and fail safe or fail secure options, with the ET26 in Grade 1 field reversible construction. Falcon offers the 510L-FSA/FSE electrified heavy duty trim for 25 Series devices, and Von Duprin the E360L-BE-03 electric passage trim for 33/35A.

The Delaney 504L is night latch only, so the lever is always locked until a key releases it. For an opening that needs the lever free, look at passage trims such as the Corbin Russwin 3310AET for ED3000 Grade 1 devices, the Corbin Russwin x810ET for ED4000 series, or the Arrow SRX01 Sierra lever with rose for ED910, S1150 and S1250 devices. If you want key control of an unlocked or locked lever state, storeroom trims like the Design Hardware KIL storeroom for 1000 and 2000 series devices or the Tell EDELT80 escutcheon lever trim are the alternative.

The Delaney 504L is built for 1-3/4 inch to 2 inch doors and will cover stock hollow metal doors with a 161 cutout. Among comparable lever trims, the Pamex E9000 storeroom L3 lever trim covers 1-3/8 inch to 2 inch. The Tell escutcheon lever trims, EDELT53 entry and EDELT80 storeroom, are rated 1-3/8 inch to 1-3/4 inch, so they stop short of a full 2 inch door.

Night latch, like the Delaney 504L, keeps the outside lever rigid and dead until a key is turned, so the lever itself never retracts the latch on its own. A storeroom trim keeps the lever locked but the key unlocks the lever to operate the latch. If you want key-only entry with a lever purely as a pull once the key is turned, night latch is the one. For storeroom trim in this class, look at the Design Hardware KIL storeroom trim or the Pamex E9000 storeroom L3 lever.

Several night latch lever trims sit in the same slot. The Sargent 704ET is a Grade 1 heavy duty night latch lever trim with field reversible operation, and the 704-ETL is the PE Series version with key retract. Dorma YR03R is a wide stile escutcheon night latch lever trim supplied less cylinder. Corbin Russwin VT957ET is a nightlatch escutcheon for ED5000 Series devices. Match the trim to the exit device you already have on the door, since exit trim is device specific.

The Delaney 504L only does night latch, key released. For classroom function lever trim, the Falcon 510L is heavy duty for 24/25 Series devices and the Falcon 179L is medium duty for 1790 Series, while the Accentra 446F is a Grade 1 classroom trim with the Augusta lever. Dexter offers the ED1000T-CLRM-TP-NC Grade 1 classroom trim in a thumbpiece and pull plate configuration with a cylinder, supplied less cylinder.

Two: US26D dull chrome and US19 black. US26D is the satin chrome look that matches most commercial door hardware already hanging in schools and offices; US19 is a flat black for storefront and modern openings.

A lever gives you something to grip once the key has retracted the latch, and the Delaney 504L SD lever is ADA compliant for that reason. A pull trim does the same job with a fixed handle instead of a lever, for example the Design Hardware 2P-03NL pull trim with cylinder hole for 1000R and 2000R devices, or the Dexter ED1500 nightlatch trim with a raised lip pull plate. Pulls take more abuse in high traffic service doors; levers are the accessible option.

The Delaney 504L SD lever trim is offered in US26D dull chrome and US19 black. If the opening calls for a finish outside those, other night latch lever trims to look at are the Sargent 704ET and 704-ETL, the Sargent 744 freewheeling Grade 1 trim where the key retracts the latch for 8700 and 8900 surface vertical rod and mortise devices, and the Corbin Russwin VT957ET nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices.
