Sure-Loc DB201-RMT 11P – Frequently Asked Questions

1) Will the Sure-Loc Round Mountain deadbolt fit a 2-inch thick door?
Yes. The Round Mountain DB201 single cylinder deadbolt covers doors from 1-3/4 to 2-1/4 inches (45-55mm) thick, so a 2 inch door is in range. Note the bottom of that range: at 1-3/8 inches, which is common on older interior doors, this one is out of spec. For a thinner door look at something like the Dexter DB2000 single cylinder, rated 1-3/8 to 1-3/4 inches.
2) Does the Sure-Loc Round Mountain deadbolt work with a 2-3/8 inch backset, or do I need 2-3/4?
Either. The latch handles both 2-3/8 inch and 2-3/4 inch backsets (60-70mm), which are the two standard bore spacings on residential doors, so it drops into existing prep without measuring twice. Handing is reversible as well, so the same unit goes on a left or right hand door.
3) Can I get Sure-Loc Round Mountain deadbolts keyed alike across a house or a rental unit?
Yes. Keying is selected on the order as either keyed different or keyed alike, at no added charge, so a set of doors can run on one key. You also pick the keyway: 5 pin KW1 (the Kwikset/Weiser standard) or 5 pin SC1 (Schlage), which lets you match whatever the rest of the building is already keyed to.
4) Is the Sure-Loc Round Mountain deadbolt rated for a commercial opening?
No. It is a residential deadbolt, built for house and apartment entry doors. For a commercial or institutional door, look at the Grade 1 or Grade 2 options instead: the Accentra D111 Grade 1 with 2-3/8 inch backset, the Arrow DBX61 Grade 2, or the Cal-Royal CB160 Grade 2 with a tamper-resistant cylinder guard.
5) Will the Round Mountain deadbolt go into an existing deadbolt hole without new drilling?
In most cases yes. It is a bored (tubular) deadbolt built for standard residential door prep, and because the backset adjusts between 2-3/8 and 2-3/4 inches it lands on whichever of the two standard bore positions your door already has. Confirm the door thickness is 1-3/4 to 2-1/4 inches before you pull the old one.
6) What is a commercial Grade 1 alternative to the Sure-Loc Round Mountain single cylinder deadbolt?
The Sure-Loc Round Mountain deadbolt is a cylinder x thumbturn deadbolt built for residential openings. For a Grade 1 cylinder x thumbturn deadbolt, the Accentra D111 is Grade 1 with a 2-3/8 inch backset and fits doors 1-3/8 to 1-3/4 inches thick, the Dexter DB1000-SCT is Grade 1 and fits 1-3/8 to 1-7/8 inch doors, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. Note the Round Mountain covers thicker doors, 1-3/4 to 2-1/4 inches, so on a heavy or built-up door the Sure-Loc range may be the one that fits.
7) What should I use instead of the Round Mountain deadbolt on a door that needs keyed access from both sides?
The Sure-Loc Round Mountain is cylinder x thumbturn, so the inside is a turn piece and cannot be keyed. For a key-both-sides opening, the Dexter DB1000-DCT is a Grade 1 double cylinder deadbolt for 1-3/8 to 1-7/8 inch doors, the Dexter DB2000-DCT is Grade 2 for 1-3/8 to 1-3/4 inch doors, and the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt gives a double cylinder in a round contemporary trim if you want the styling closer to the Round Mountain.
8) I need a deadbolt on a fire rated door - is the Round Mountain the right pick?
The Sure-Loc Round Mountain is a residential-duty deadbolt. For fire rated openings, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw carrying a fire rating and fitting 1-3/8 to 1-3/4 inch doors, the Hager 3115 is a Grade 2 cylinder x thumbturn with a Schlage C keyway and a fire rating, and the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
9) What looks like a substitute for the Round Mountain deadbolt but will not work in the same door prep?
The Sure-Loc Round Mountain is a bored tubular deadbolt for standard residential door prep with a 2-3/8 or 2-3/4 inch backset. Several items that read as deadbolts need different preparation: the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, the Dormakaba D900 is a small case mortise deadbolt, the Codelocks CL200 is a surface mounted deadbolt with key override, and the Arrow 460 is a mortise lock strike rather than a lock at all. The Callan Model 205S is a one-sided half-bore deadbolt with no outside cylinder.
10) I need a deadbolt for a classroom or institutional opening - what takes the place of the Round Mountain there?
The Sure-Loc Round Mountain is a residential cylinder x thumbturn deadbolt. For institutional openings, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset and the Falcon D211 is the Grade 2 medium duty classroom version. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 to 1-3/4 inch doors, and the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 to 2-1/4 inch doors.
11) Is this a single cylinder or double cylinder deadbolt?
Single cylinder: key outside, thumbturn inside. That is the cylinder x thumbturn function. If you have glass next to the door and your local code pushes you to key both sides, this is not the part. A double cylinder option in a similar contemporary round trim would be the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt.
12) What is the Sure-Loc Round Mountain deadbolt actually made of?
The housing is solid brass with a stainless steel substrate, and the bolt is cut resistant with hardened steel rolling inserts, which spin against a hacksaw blade instead of letting it bite. Solid brass holds up better on an exterior door than a plated zinc casting.
13) Which deadbolt gives me the same round contemporary look as the Round Mountain from another brand?
The Sure-Loc Round Mountain is a contemporary-styled round deadbolt with a solid brass housing. Close stylistic peers include the Bravura 310RC Elite, a Grade 2 contemporary round cylinder x thumbturn deadbolt, the Bravura 310B Elite in a traditional round trim, the Callan Model 200S-G2 Grade 2 single cylinder round trim deadbolt, and the Brinks Raleigh Series transitional round single cylinder deadbolt with a 4-way adjustable backset. If the design direction is square rather than round, the Bravura 310SC Elite and Brinks Mendocino Series are the square-trim equivalents.
14) Is there a simpler deadbolt than the Round Mountain for a low traffic rental door?
The Sure-Loc Round Mountain uses a solid brass housing and a cut resistant bolt with hardened steel rolling inserts. If that level of build is more than the opening calls for, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors, the Cal-Royal LSD is Grade 3 with an ADA ergonomic thumbturn over the same thickness range, and the Callan Model 200S is a Grade 3 single cylinder deadbolt in square trim.
15) Can I get the Round Mountain deadbolt with an interchangeable core or keypad instead of a standard key cylinder?
The Sure-Loc Round Mountain is a keyed mechanical deadbolt offered with a 5 pin KW1 or 5 pin SC1 keyway and is not electronic. If you need a small format interchangeable core, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core and the Arrow E61 26D IC is a single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors. For code or credential access, the Delaney KP400 is a Grade 2 electronic deadbolt and the Codelocks CL2200 is an electronic surface deadbolt.
16) What deadbolt should I use on an exit door where nobody should be keying in from outside?
The Sure-Loc Round Mountain has a keyed cylinder outside and a thumbturn inside. For an exit-only opening, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and a thumbturn inside, fitting 1-3/8 to 1-3/4 inch doors, and the Callan Model 205S is a one-sided half-bore deadbolt. If you want the reverse - keyed outside with a blank inside - the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock in cylinder x blank for 1-3/4 inch doors.
17) Which brass-bodied deadbolt is comparable to the Round Mountain if I want a decorative finish for a front entry?
The Sure-Loc Round Mountain has a solid brass housing and comes in Vintage Bronze, Satin Nickel, Flat Black and Satin Brass. On the decorative side, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt, the Emtek 8323 Modern Disc is a brass deadbolt in double cylinder, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt. Of those three, only the Tuscany matches the Round Mountain's cylinder x thumbturn function.
18) Does the Round Mountain deadbolt match the Ridgecrest collection trim style?
It is part of the Ridgecrest collection in a contemporary Round Mountain style, so the round rose on the deadbolt lines up visually with the other Round Mountain trim on the same door or the rest of the openings in the unit.
