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

The 504L CT lever trim is always locked from the outside. The lever is dead until a key is turned in the cylinder, which releases it and lets you retract the latch and pull the door open. Let go of the key and it relocks. Free egress still comes from the exit device on the inside, since this is exterior trim only. If you want a lever that stays free for entry during business hours, night latch is the wrong function, look at a storeroom or entry trim instead.

Two ways to buy it. The standard build ships with a Schlage C 6-pin keyway cylinder, and a KW1 5-pin cylinder is available as an option. The other build is SFIC, small format 6-pin interchangeable core, supplied less core, so a locksmith drops in your own core and the opening joins the existing master key system. If you are running a facility on SFIC, order the less-core version and nothing else is needed but the core.

The Sargent 704ET is the nearest equivalent in lever-style night latch trim - it is a Grade 1, heavy duty night latch lever exit device trim in the Sargent 700 Series with field reversible operation. The Delaney 504L is also a night latch function CT style lever exit trim, meaning the lever is released by key and is otherwise always locked. Sargent also offers the 704-ETL, a Grade 1 heavy duty night latch lever trim with key retract function for PE Series devices. The practical difference is device compatibility: the Sargent trims are built to their own exit device series, while the 504L is prepped to cover stock hollow metal doors with a 161 cutout.

Several pull-style night latch trims cover the same function without a lever. The Design Hardware 2P-03NL is a Grade 1 pull trim with a cylinder hole for the 1000R and 2000R exit devices, and the Dexter ED1500T-PULL-NC is a Grade 1 nightlatch function trim with a raised lip pull plate. Von Duprin's 110MD-NL is a Grade 1 heavy duty night latch cylinder assembly for metal and wood doors used with 22, 55 and 98/99 series devices - cylinder only, no pull or lever. The Delaney 504L differs in that it gives you a CT style lever for the pull, which matters where ADA compliant operable hardware is required on the outside of the opening.

Yes, for an opening that must allow free entry during the day you want a passage or classroom function rather than night latch. The Delaney 504L keeps the lever locked at all times and releases it only by key. For always-free outside entry, the Arrow SRX01 is a passage function Sierra lever trim with rose for ED910, S1150 and S1250 devices, and Corbin Russwin offers passage trims across its Grade 1 lines - the 3310AET for ED300 Series, the x810ET for ED4000 Series, and the x910ET heavy duty trim for ED5200S, ED5200, ED5400 and ED5800 Series. For key-controlled outside lever that can be left unlocked, the Falcon 510L is a heavy duty classroom function lever trim for 24/25 Series devices.

The Delaney 504L is built for doors 1-3/4 inch to 2 inch thick, so a 1-3/8 inch door falls below its range. Trims that cover 1-3/8 inch include the Tell EDELT53 keyed entry escutcheon lever trim and the Tell EDELT80 storeroom escutcheon lever trim, both rated 1-3/8 inch to 1-3/4 inch, and the Pamex E9000 Grade 1 storeroom lever trim, rated 1-3/8 inch to 2 inch. Note that those are entry and storeroom functions rather than night latch, so confirm the function your opening requires before substituting.

Night latch suits a door you want locked around the clock with keyed access only, back of house, service entries, stair discharge. Staff exit freely on the push bar and nobody gets in without a key. If you need the outside lever free at times or unlocked by a thumbturn schedule, pick an entry or storeroom function instead. ZenSupply carries the Design Hardware KIL Entry trim in entry function and the KIL Storeroom trim in storeroom function, both Grade 1 with a Schlage C keyway, as the alternatives.

No. The 504L is mechanical key-operated trim with no electrical option. For card reader or fail safe/fail secure control you need electrified trim: Command Access builds the ET15, ET25 and ET26 with 12V/24V operation and fail safe or fail secure selection, and the Falcon 510L-FSA/FSE is the electrified heavy duty lever trim for 25 Series devices.

Night latch and storeroom trims both keep the outside lever locked, but on the 504L the key releases the lever - it is a momentary key retract, and the lever is otherwise always locked. Storeroom trims such as the Design Hardware KIL Storeroom, the Tell EDELT80 escutcheon lever trim, the Pamex E9000 Grade 1 L3 lever trim, and the Marks USA M195F lever and rose trim with spring loaded roses give you a lever the key unlocks for entry. If your spec sheet calls out storeroom, those are the direct matches; if it calls out night latch or key-retracts-latch, the 504L is the correct family.

Among escutcheon-mounted night latch lever trims, the Dorma YR03R is a wide stile exit device lever trim with escutcheon and R lever in nightlatch function supplied less cylinder, the Corbin Russwin VT957ET is a nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices, and the Accentra AU-441F is a night latch keyed lever trim with the Augusta lever design. The Delaney 504L uses the CT lever on an escutcheon and is offered in US19 Black, US26D Dull Chrome and US10B Oil Rubbed Bronze, with either a Schlage C 6-pin standard cylinder or a less-core small format interchangeable core prep.

The Sargent 744 is a Grade 1 night latch trim from the 70 Series made for surface vertical rod and mortise devices in the 8700 and 8900 Series, with freewheeling trim where the key retracts the latch. The Delaney 504L is a CT style lever night latch trim prepped to cover stock hollow metal doors with a 161 cutout, so confirm your device and door prep match before ordering either.

Three: US26D dull chrome, US10B oil rubbed bronze, and US19 black. Each is available with either the C 6-pin standard cylinder or the less-core SFIC prep, so a property manager matching an existing run of doors can hold the finish constant and change only the keying method.

Yes. The Tell EDTHP53 is a thumbpiece exit device trim in keyed entry function for doors 1-3/8 inch to 1-3/4 inch, and the Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom function trim with thumbpiece, pull plate and cylinder prep supplied less cylinder. Those suit openings where a thumbpiece is specified; the Delaney 504L uses a CT style lever and is ADA compliant, which is often the deciding factor on accessible routes.

If the outside needs a lever with no cylinder and no key control, the Falcon 212L is a medium duty blank escutcheon lever trim for 20 Series devices, the Accentra 426F is an Augusta lever escutcheon trim for 6000 and 1800 Series devices, and the Von Duprin 210K-BE is a Grade 1 heavy duty knob trim with blank escutcheon for 22 Series. The Delaney 504L is the opposite specification - it is keyed, with a Schlage C 6-pin keyway standard and KW1 5-pin optional, or a small format interchangeable core prep supplied less core.
