Marks USA 175L26D-3/4 – Frequently Asked Questions

1) Does the Marks USA 175L privacy lever come in a 2-3/8 inch backset for residential-depth door prep?
Yes. The 175L privacy lever is ordered in either a 2-3/4 inch or a 2-3/8 inch backset, and every finish offered (US3 bright brass, US10 satin bronze, US10B oil-rubbed dark bronze, US26D satin chrome) is available in both. 2-3/4 is the usual commercial prep; 2-3/8 is what you will find on lighter and older interior doors. Measure from the door edge to the center of the existing bore before you pick.
2) How does the privacy function on the Marks 175L actually work, and can staff get in during an emergency?
The outside lever locks from a pushbutton in the inside lever. Turning the inside lever or simply closing the door pops the button back out and unlocks it, so nobody gets accidentally locked out of a restroom or patient room. The outside lever carries an emergency release so maintenance or staff can get in from the corridor side. That is ANSI Function F76.
3) Will the Marks 175L latch into the strike already in my frame?
Depends on what is in there now. The 175L has a 1/2 inch latch throw and ships with an ANSI strike measuring 1-1/4 x 4-7/8 inches with a 1-1/4 inch lip and square corners. If your frame is prepped for that standard ANSI/ASA cutout, the included strike drops straight in. A frame cut for a small T-strike or a radius-corner strike will need the prep changed or a filler plate.
4) Is the Marks 175L ADA compliant for restrooms in a public building?
Yes. The American lever design is ADA compliant, and the lock is ANSI/BHMA certified and UL Listed at Grade 2. That combination is what specifiers usually want for restrooms and patient rooms in schools, offices and healthcare facilities.
5) Can I use the Marks USA 175L on a door that needs to be keyed?
No. The Marks USA 175L is non-keyed, with privacy pushbutton operation only. For a keyed opening in a cylindrical bored prep, look at the Orca Hardware OCL250 Grade 2 entrance lockset, the Stanley Security QCL150 entry lever with a 2-3/4 inch backset latch and 4-7/8 inch x 1-1/4 inch ASA strike, or the Dorma C853 single cylinder entry lever, which is Grade 1 and covers 1-3/8 inch to 2-1/4 inch doors.
6) What is an equivalent privacy lever lockset to the Marks USA 175L in another brand?
The Orca Hardware OCL240 is the closest straight equivalent: a Grade 2 cylindrical privacy lockset in the same Privacy/Bed/Bath function as the Marks USA 175L, rated medium duty. Both are non-keyed bored locksets for bed and bath openings. The 175L carries ANSI Function F76 with a pushbutton on the inside lever and an emergency release outside, a 1/2 inch latch throw and an ANSI 1-1/4 inch x 4-7/8 inch strike with square corner.
7) What is the latch face size for door edge prep on the Marks 175 Series?
The front measures 1-1/8 x 2-1/4 inches, so it mortises into a standard bored-lock edge prep. Combined with the 2-3/4 inch backset and standard cylindrical cross-bore, the 175L drops into openings already prepped for a commercial bored lockset without new holes.
8) Grade 2 privacy lever vs Grade 1 for a high-traffic school restroom, which should I buy?
The 175L is Grade 2, from the Marks Survivor 175 line, and it is aimed at commercial use where budget matters. If the opening is abused daily and the spec calls for Grade 1, the Cal-Royal CAL20 is an extra heavy duty Grade 1 privacy lock covering 1-3/8 to 2 inch doors. Same function, heavier cycle rating, wider thickness range.
9) I need a passage lever to match these privacy levers on the same corridor. What pairs with the Marks 175L?
The 175L only covers the privacy function, so closets and hall doors need a separate passage lockset. Options we carry in Grade 2 cylindrical passage include the Orca OCL210 passage lockset and the Dorma CL701. For a heavier Grade 1 passage lever there is the Cal-Royal CAL30, rated for 1-3/8 to 2 inch doors. Lever style and finish will not be an exact visual match to the Marks American lever, so if appearance matters across the corridor, stay within the Marks line for the companion functions.
10) Can I use the Marks 175L on an apartment bedroom or bathroom door I'm turning over?
It works if the door is 1-3/4 inches thick. The 175L is built for commercial duty rather than light residential, which is why property managers use it in multi-tenant buildings where privacy levers get replaced often. Many apartment interior doors are 1-3/8 inches though, and this lock will not fit those.
11) Is the Marks 175L handed? Do I need to specify left or right?
No handing to specify. It is a cylindrical bored lockset, so the lever is reversible in the field and one part number covers both left and right hand openings. The only two things you choose when ordering are backset, 2-3/8 or 2-3/4, and finish.
12) The door does not need to lock at all. What is the passage version instead of the Marks USA 175L?
For a latching but non-locking opening, use a passage lockset rather than the privacy 175L. The Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset, and the Cal-Royal CAL30 Calypso is a Grade 1 extra heavy duty passage lock covering 1-3/8 inch to 2 inch doors. The Marks USA 175L is specifically Privacy/Bed/Bath, with the outside lever locked by a pushbutton on the inside lever.
13) What is the difference between the Marks USA 175L and an electronic privacy lock like the Schlage CO-100?
The Marks USA 175L is a mechanical Grade 2 cylindrical privacy lockset, non-keyed, operated by a pushbutton on the inside lever with an emergency release outside. The Schlage CO-100-CY-40-KP is a standalone electronic cylindrical lock in privacy function, Grade 1 heavy duty, with keypad and cylinder options, for 1-3/4 inch doors. The Alarm Lock Trilogy 4100 is another Grade 1 electronic privacy cylindrical lock, for 1-5/8 inch to 1-7/8 inch doors. Choose electronic only if you need code-based credentials; the 175L needs no power.
14) For a classroom door, should I specify the Marks USA 175L?
No, the Marks USA 175L is a Privacy/Bed/Bath function intended for bed, bath and single-occupant rooms. For classroom openings, the TownSteel XCE-2000 and XCE-9000 are Grade 1 heavy duty classroom electronic cylindrical locksets for 1-3/4 inch to 2 inch doors, and the Schlage XE360M is a Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors.
15) What finishes does the Marks 175 Series privacy lever come in for matching existing hardware?
Four finishes: US3 bright brass, US10 satin bronze, US10B oil-rubbed dark bronze, and US26D satin chrome. US26D is the usual match for commercial buildings running satin chrome throughout; US10B suits hospitality and residential-style corridors. All four are offered in both backsets, so you can standardize a finish across a building without worrying about door prep depth.
