Marks USA 175F26D-3/4 – Frequently Asked Questions

1) Will the 175F drop into my existing ANSI strike prep, or do I have to cut the frame?
It ships with an ANSI strike measuring 1-1/4 by 4-7/8 inches with a 1-1/4 inch lip and square corners, which is the standard commercial frame prep, so on a frame already cut for ASA strike you drop straight in. The latch front is 1-1/8 by 2-1/4 inches for the door edge mortise, and the latch throw is 1/2 inch, so the frame face needs to sit within that of the door edge for reliable latching. Frames prepped only for a small T-strike will need to be modified.
2) I need to key this into my existing master key system. Can I order the Marks 175F without a cylinder?
Yes. Cylinder choice is a required selection on the 175F: take Standard if you want it supplied as a complete keyed lock, or the G3 less cylinder option if your locksmith is fitting a cylinder from your own keyway and master system. Less-cylinder is the usual pick for a facility standardizing on one key system across the building.
3) Does anything else use the same ANSI strike prep as the Marks USA 175F?
The Marks USA 175F ships with an ANSI strike measuring 1-1/4 inch by 4-7/8 inch with a 1-1/4 inch lip and square corners, and it is furnished in 2-3/8 inch and 2-3/4 inch backsets. The Stanley QCL150 entry lever uses a 4-7/8 inch by 1-1/4 inch ASA strike with a square 2-3/4 inch backset latch, and the Stanley QTL230E passage lever uses a 4-7/8 inch by 1-1/4 inch ANSI strike with an adjustable square latch, so both drop into the same frame cutout. By contrast the Stanley QCL200 is supplied with a 118F ANSI 1-1/8 inch by 2-3/4 inch strike, which is a different frame prep.
4) Is the Marks 175F lever ADA compliant for a school or hospital corridor?
The 175F uses an American lever style that meets ADA accessibility requirements, so it operates without tight grasping, pinching or wrist twisting. It's also ANSI/BHMA certified and UL Listed, and it's built as a commercial lock rather than a residential one. For institutional buyers standardizing a building, that gives you the accessibility and certification basis on every opening that takes a storeroom function.
5) Is a Grade 2 lock like the Marks 175F enough for a busy school storeroom, or should I spend up to Grade 1?
The 175F is certified Grade 2, which under ANSI/BHMA is the medium-duty commercial tier, and Marks builds the 175 Survivor Series to push toward Grade 1 performance at that level. For a storeroom or utility door that sees moderate traffic it's a sound pick. If your spec sheet literally calls for Grade 1 cylindrical, you'd be looking at something like the Dorma C150 or the Dorma C853, both Grade 1 keyed cylindrical levers, rather than trying to substitute the 175F.
6) What finishes does the Marks 175F storeroom lever come in, and can I match the other doors in the building?
Four finishes are offered: US26D satin chrome, US10 satin bronze, US10B oil-rubbed dark bronze and US3 bright brass. Every finish is available in both the 2-3/8 and 2-3/4 inch backset. US26D satin chrome is the standard institutional finish and the one most commercial buildings are already standardized on, so that's usually the match if you're replacing a handful of doors in an existing fleet.
7) I need a passage or privacy lever to match the Marks 175F on adjacent doors. What do I use?
The 175F is a keyed storeroom lock only, so for the other functions on the same run of doors you need a different item. Within ZenSupply's Grade 2 cylindrical range, the Orca OCL210 covers passage, the OCL240 covers privacy, the OCL250 covers keyed entrance, and the OCL2170 is a half dummy. Bear in mind those are a different brand, so the lever style and finish will not visually match the Marks American lever.
8) Should I use a mechanical lock like the 175F or go electronic for a storeroom?
Mechanical makes sense when the door is keyed into an existing system and you don't need an audit trail or code changes; the 175F is a straight cylindrical key-in-lever with no batteries or wiring to maintain. Go electronic when you need to hand out and revoke codes or track who opened the door. On 1-3/4 inch doors ZenSupply's electronic cylindrical options include the TownSteel XCE-2000 keypad lockset and the Schlage XE360M wireless classroom/storeroom lock; the Alarm Lock Trilogy DL2700 is another keypad route, though it lists for 1-5/8 to 1-7/8 inch doors.
9) Is the Marks 175F handed? Do I need to specify left or right?
No handing to call out. The 175F is a cylindrical bored lockset, and cylindrical levers of this type are non-handed in the field, so the same unit serves a left or right hand opening. What you do have to specify is the backset (2-3/8 or 2-3/4 inch), the finish, and whether you want it standard or less cylinder.
10) The door does not need a key - what do I use instead of the Marks USA 175F?
The 175F is a keyed storeroom lockset, so for openings that need no key cylinder you want a non-keyed function instead. The Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset, the Orca OCL240 is a Grade 2 medium duty privacy cylindrical lockset, and the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lockset covering 1-3/8 inch to 2 inch doors. For a bed or bath opening, the Cal-Royal CAL20 is a Grade 1 privacy lock over that same 1-3/8 inch to 2 inch range.
11) Can I use the Marks USA 175F on an access control system, or do I need something else?
The 175F is a mechanical cylindrical lockset with no electrical connection. For a door tied into access control, the SDC Electra 7200 Series is a solenoid controlled cylindrical lock with dual 12/24VDC voltage for 1-3/4 inch to 2 inch doors, and the Schlage NDEB ENGAGE Series is a Grade 1 wireless cylindrical lock using 2.4 GHz Bluetooth Low Energy for 1-5/8 inch to 2 inch doors. The Marks 175F is ordered either standard or as G3 less cylinder if the keying is being supplied separately.
