Marks USA 130K/32D-4C – Frequently Asked Questions

1) Will the Marks USA 130K deadbolt fit a 1-3/4 inch commercial door?
Yes. The 130K covers door thicknesses from 1-3/8 to 1-7/8 inches, so a standard 1-3/4 inch commercial door is in the middle of the range, and it also handles the thinner 1-3/8 inch doors common in older interior openings and the heavier 1-7/8 inch leaves. Prep is a standard 2-1/8 inch cross bore on a 2-3/4 inch backset, so on a door already bored for a deadbolt at that backset the unitized assembly drops straight in.
2) Can I put my own Medeco or Best SFIC cylinder in a Marks USA 130K deadbolt?
Yes, and that is one of the main reasons locksmiths spec the 130K. It accepts Medeco, Kaba, Multilock, ASSA and other high security cylinders, most manufacturers' conventional cylinders, and IC core models for Best size cores. As supplied it comes with a Marks C keyway, 6-pin cylinder and two keys, so if the building is on a Marks C system you can key it into the existing bitting; if it is on a restricted or interchangeable core system, swap the cylinder and keep the same lock body.
3) What is the difference between the 130K and the other 130 series functions like the M or S?
The K suffix is the function code, and it is cylinder by turnpiece: key on the outside, thumbturn inside. The rest of the 130 family changes what is on each face. L is a communicating single cylinder, M is double cylinder with a key required on both sides, S is classroom, and X is turnpiece by blank plate with no keyed side at all. Pick K for a normal exterior or tenant door where you want free egress by turning the thumbturn. Pick M only where local egress code allows a key on the inside, and X where the door is secured from inside and never keyed.
4) Is the Marks USA 130K deadbolt strong enough for a high-traffic commercial entrance?
It is rated ANSI 156.5 Grade 1 for deadbolts, which is the top commercial tier and the level normally specified for entrances, stairwells and tenant doors that see heavy daily use. Physical attack resistance comes from tapered cylinder collars, which give a wrench nothing to bite on, and a steel shutter system that blocks access to the mounting screws once the door is locked, so the lock cannot be unscrewed from outside. The bolt and trim are stainless steel.
5) I have a 2-3/8 inch backset deadbolt prep, is the Marks 130K the right part?
No. The 130K is built for a 2-3/4 inch backset, which puts the cylinder further in from the door edge than a 2-3/8 inch prep allows, and the two are not interchangeable without re-boring. For a 2-3/8 inch backset Grade 1 deadbolt, the Accentra D111 is a cylinder-by-thumbturn Grade 1 unit specified at 2-3/8 inches. Another route is a deadbolt with an adjustable backset that covers both, such as the Falcon D111, which is Grade 1 with an adjustable backset.
6) What is the closest Grade 1 single cylinder deadbolt to the Marks USA 130K if the Marks C keyway does not fit the building's key system?
The Accentra D111 is a Grade 1 single cylinder deadbolt in the D Series with a cylinder x thumbturn function, the same operation as the Marks USA 130K, which carries a Grade 1 rating and a cylinder x thumbturn function with a Marks C keyway. The Dexter DB1000-SCT is also a Grade 1 cylinder x thumbturn deadbolt and covers a 1-3/8 inch to 1-7/8 inch door thickness range. Both give a locksmith a Grade 1 single cylinder deadbolt on a different keyway family when the Marks C profile is not what the site is keyed to.
7) Which deadbolt matches the Marks USA 130K door thickness range on doors thicker than 1-3/4 inch?
The Marks USA 130K covers doors from 1-3/8 inch to 1-7/8 inch. Among Grade 1 single cylinder deadbolts, the Dexter DB1000-SCT lists the same 1-3/8 inch to 1-7/8 inch range. The Accentra D111 is specified for 1-3/8 inch to 1-3/4 inch, so a 1-7/8 inch door falls outside it. For heavier openings, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock is specified from 1-3/4 inch to 2-1/4 inch, though it is a cylinder x blank deadlock rather than a thumbturn function.
8) What should be used instead of the Marks USA 130K when the opening needs a key on both sides?
The Marks USA 130K is a single cylinder deadbolt, keyed outside with a thumbturn inside. For a key on both faces, the Dexter DB1000-DCT is a Grade 1 double cylinder deadbolt covering 1-3/8 inch to 1-7/8 inch doors, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. In Grade 2, the Delaney LU Series is a double cylinder deadbolt offered in stainless steel US32D, and the Hager 3214 is a double cylinder deadbolt on the Schlage C keyway for 1-3/8 inch to 1-3/4 inch doors. Note that double cylinder deadbolts are restricted on egress doors in many jurisdictions, so confirm the code requirement for the opening.
9) Which deadbolt takes an interchangeable core if the facility standardizes on SFIC?
The Marks USA 130K accepts IC core models for Best size cores along with conventional cylinders from most manufacturers. If the core is to be supplied separately, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC and shipped less core, for 1-3/8 inch to 1-3/4 inch doors. The Deltana CL200LAIC is a Grade 2 single cylinder deadbolt built for an interchangeable core, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
10) Does the Marks USA 130K carry a fire rating, and which comparable deadbolt is fire rated?
The Marks USA 130K is ANSI 156.5 Grade 1 as a deadbolt; the UL 3 hour fire rating on the Marks 130 platform applies to the deadlatch models. Where the opening needs a fire rated deadbolt, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and Hager lists a fire rating on the 3118 Grade 1 classroom deadbolt with Schlage C keyway and 6-pin cylinder as well as on the 3215 single cylinder deadbolt with 1 inch throw.
11) Which products look like substitutes for the Marks USA 130K but will not work in the same door prep?
Several deadbolt-named items are a different part entirely. The Arrow 460 is a mortise lock strike for latchbolt by deadbolt functions with a straight lip, not a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the BEST 8T is a T Series tubular deadbolt tube component rather than a complete lock. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket rather than the 2-1/8 inch bore the Marks USA 130K installs into. The Detex DX Series is a hinge side locking deadbolt with multi-point security, a different opening treatment altogether.
12) What else could I buy instead of the Marks 130K, and how do they differ?
Staying at Grade 1 single cylinder, the Dexter DB1000 covers the same 1-3/8 to 1-7/8 inch thickness range, and the Deltana CL200LM and Delaney LM Series are Grade 1 cylinder-by-thumbturn units, with the Delaney supplied less core for an interchangeable core system. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. If Grade 1 is more than the opening needs, the Arrow DBX61, Cal-Royal CB160 and Dexter DB2000 are Grade 2 single cylinder deadbolts. What separates the 130K from most of these is the open cylinder compatibility, so it takes Medeco, ASSA, Multilock or Best cores without changing the lock.
13) Should I use a bored deadbolt like the Marks 130K or a mortise deadlock on my door?
Go bored if the door is already prepped with a 2-1/8 inch cross bore or you are drilling new; the 130K is a unitized assembly that installs into that standard prep, which keeps retrofit labor low. A mortise deadlock, like the Dormakaba D900 small case mortise deadbolt or the Emtek 2050 European mortise deadbolt, needs a pocket routed into the door edge, so it is the choice when the door already has a mortise cavity or when you want the case fully concealed in the stile. For an aluminum or hollow metal door with an existing 2-1/8 inch bore, the bored deadbolt is the far simpler swap.
14) Do the Marks 130K deadbolts come keyed alike so one key runs all my doors?
As supplied the 130K is keyed different, with a 6-pin Marks C cylinder and two keys per lock, so out of the box each door has its own key. If you are standardizing a building on one key, the practical route is to have the cylinders keyed to your existing Marks C system, or pull the factory cylinders and fit your own conventional or interchangeable cores; the 130K takes Best size IC cores and most conventional cylinders, so a property manager running a master key system can put the whole fleet on it without changing lock bodies.
15) Does the Marks 130K deadbolt have a handing, and does it come with everything needed to install?
No handing to specify. A deadbolt has no latch bevel, so the same unit works on a left or right hand door and either swing. It arrives as a unitized assembly with the #1335 strike, two keys and the 1 by 2-1/4 inch latch front, so the only thing you need on site is the correct 2-1/8 inch cross bore at a 2-3/4 inch backset and the frame prepped deep enough for the 1 inch throw.
16) Is there a lighter duty alternative to the Marks USA 130K deadbolt for interior or low traffic doors?
The Marks USA 130K is a Grade 1 commercial deadbolt. Where a Grade 1 rating is not required by the spec, the Arrow DBX61 is a Grade 2 single cylinder deadbolt in the DBX Series with the same cylinder x thumbturn operation, and the Dexter DB2000-SCT is a Grade 2 cylinder x thumbturn deadbolt covering 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal CB160 is another Grade 2 single cylinder deadbolt, supplied with a tamper-resistant cylinder guard. Below that, the Cal-Royal ED500 is Grade 3 with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors.
17) Which deadbolt is the alternative to the Marks USA 130K on a door that must not be keyed at all?
The Marks USA 130K is keyed, with a Marks C six pin cylinder outside and a thumbturn inside. For an opening that needs thumbturn operation only, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate by thumbturn function for 1-3/8 inch to 1-3/4 inch doors. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt where only one face of the door is prepped.
18) What is the difference between the Marks USA 130K and the Corbin Russwin DL3211 or DL2211 deadlocks?
The Marks USA 130K is a cylinder x thumbturn deadbolt, so it can be retracted from the inside without a key. The Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock in the DL3200 Series with a cylinder by blank trim for 1-3/4 inch doors, and the DL2211 is a Grade 1 cylindrical deadlock, cylinder x blank, in the DL2200 Series with a classroom function for 1-3/4 inch doors. A blank plate outside face means no operation from that side, which is a different security intent from the 130K's inside thumbturn. Marks also builds the 130 platform in an X configuration with a turnpiece by blank plate if that split is what the opening needs.
19) What is the electronic or keypad alternative to a Marks USA 130K deadbolt?
The Marks USA 130K is a mechanical keyed deadbolt on a Marks C six pin cylinder. For credential or code entry on the same style of opening, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Codelocks CL2210 is an electronic mortise deadbolt. For multihousing RFID, Dormakaba offers the Nova-D smart electronic deadbolt and the Saffire LX-D RFID electronic deadbolt with BLE and electronic lock override.
20) Which classroom function deadbolt compares to the Marks USA 130 S configuration?
Marks builds the 130 platform in an S classroom configuration alongside the K cylinder x turnpiece. Comparable classroom deadbolts include the Falcon D111, a Grade 1 heavy duty classroom deadbolt in the D100 Series with an adjustable backset, the Falcon D211, a Grade 2 medium duty classroom function deadbolt with single cylinder operation in the D200 Series, and the Hager 3118, a Grade 1 classroom deadbolt on a Schlage C keyway with a 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors.
21) What deadbolt works when a separate deadbolt cannot be added and the lever lock has to carry it?
The Marks USA 130K is a standalone deadbolt requiring its own 2-1/8 inch bore. If the door only supports a single prep, the Falcon H2101 is a Grade 2 entrance interconnected lock in the H2 Series with a single cylinder deadbolt built in. On mortise openings, the Dormakaba D900 small case mortise dead bolt is a cylinder x thumbturn unit on SC keyways, keyed different, which fits a mortise pocket rather than a bore.
22) What finishes does the Marks USA 130K deadbolt come in?
Two: US3 bright brass and US32D stainless steel. US32D is the usual pick when the opening already has satin stainless or brushed chrome levers, closers and push plates, since it reads the same across a floor of doors. US3 bright brass is for openings standardized on polished brass trim. The lock itself is stainless steel regardless of the finish selected.
23) Which deadbolt should be specified instead of the Marks USA 130K when the exterior trim needs a decorative or square profile?
The Marks USA 130K is a commercial deadbolt offered in US3 bright brass and US32D stainless steel. Where the opening calls for architectural trim, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt and the 310RC Elite is a Grade 2 contemporary round deadbolt, both cylinder x thumbturn. The Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt, and the Baldwin Reserve contemporary round and square double cylinder deadbolts cover the two-sided keyed version of that look.
