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

1) Will the Sure-Loc Square Mountain deadbolt fit my existing door prep and backset?
The Square Mountain DB201 deadbolt fits standard residential bored prep with a 2-3/8 inch or 2-3/4 inch backset, so it drops into either common bore spacing without redrilling. Handing is reversible, so the same unit works on a left or right hand door.
2) What door thickness does the Sure-Loc DB201 deadbolt cover?
It covers doors 1-3/4 inch to 2-1/4 inch (45-55mm) thick. That means it suits a standard 1-3/4 inch door and thicker entry slabs, but it will not work on a 1-3/8 inch interior door. For a thinner door, a Dexter DB2000 single cylinder covers 1-3/8 to 1-3/4 inch.
3) Can I get several Sure-Loc Square Mountain deadbolts keyed alike for one building?
Yes. Keying is specified on the order as either keyed different or keyed alike at no added charge, so a landlord doing multiple units can put one key across a group of doors. Keyway choice is 5-pin KW1 (standard Weiser/Kwikset style) or 5-pin SC1 (Schlage style), so you can match the keys already in circulation.
4) Is this deadbolt strong enough for a commercial entrance?
The DB201 is built for residential use, with a solid brass housing and a cut resistant bolt carrying hardened steel rolling inserts. For a commercial opening where a graded lock is specified, look at a Grade 1 unit such as the Accentra D111 or the Dexter DB1000 single cylinder.
5) What is the closest square-trim alternative to the Sure-Loc Square Mountain single cylinder deadbolt?
The Sure-Loc Square Mountain deadbolt is a cylinder x thumbturn single cylinder deadbolt with contemporary square styling. For the same square look from another brand, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt in cylinder x thumbturn, and the Brinks Mendocino E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. Callan's Model 200S is a Grade 3 single cylinder square trim deadbolt in the same function.
6) I need a deadbolt with an ANSI grade for a commercial opening - what should I use instead of the Square Mountain?
The Sure-Loc Square Mountain deadbolt is specified for residential use. Where a graded commercial deadbolt is required, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw. All three use the same cylinder x thumbturn operation.
7) The Square Mountain deadbolt fits 1-3/4 to 2-1/4 inch doors - what works on a thinner 1-3/8 inch door?
The Sure-Loc Square Mountain deadbolt fits doors 1-3/4 inch to 2-1/4 inch thick. For a 1-3/8 inch door, the Dexter DB2000 single cylinder is listed for 1-3/8 inch to 1-3/4 inch, the Dexter DB1000 Grade 1 single cylinder covers 1-3/8 inch to 1-7/8 inch, and the Cal-Royal ED500 Grade 3 with adjustable backset covers 1-3/8 inch to 1-3/4 inch. Each is a cylinder x thumbturn single cylinder deadbolt.
8) I need a double cylinder version for a door with glass next to it - what replaces the Square Mountain?
The Sure-Loc Square Mountain is a single cylinder deadbolt, keyed outside with a thumbturn inside. For a keyed-both-sides opening, the Baldwin Reserve Contemporary Square deadbolt is a double cylinder in square trim, the Emtek 8323 Modern Disc is a brass double cylinder, and the Callan Model 210S is a Grade 3 double cylinder. The Delaney LU Series is a Grade 2 double cylinder in stainless steel US32D finish.
9) I key my buildings on an interchangeable core system - what deadbolt should I order instead of the Square Mountain?
The Sure-Loc Square Mountain ships keyed with a KW1 or SC1 five pin cylinder and is not an IC product. For small format interchangeable core, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt.
10) Is the Square Mountain deadbolt keyed outside and thumbturn inside?
Yes, it is a single cylinder deadbolt: key cylinder on the exterior, thumbturn on the interior. If you need a key on both sides, for instance beside glass, look at a double cylinder such as the Baldwin Reserve Contemporary Square deadbolt or the Callan 210S.
11) What finishes does the Sure-Loc Square Mountain deadbolt come in, and will they match the rest of the line?
Four finishes: Vintage Bronze (11P), Satin Nickel (15), Flat Black (FBL) and Satin Brass (SB). They are shared across the Square Mountain line, so the deadbolt coordinates with the matching handle sets on the same opening.
12) I want keyless or electronic entry instead of a keyed deadbolt like the Square Mountain - what are the options?
The Sure-Loc Square Mountain is a mechanical keyed deadbolt with no electronics. For code or credential entry, the Codelocks CL200 is a light duty surface deadbolt with key override, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
13) Is the Arrow E60 exit deadlock a substitute for the Sure-Loc Square Mountain deadbolt?
No. The Sure-Loc Square Mountain is keyed, with a cylinder outside and thumbturn inside. The Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate on the outside and a thumbturn inside, so it can only be operated from the interior. If key access from outside is needed, the Arrow DBX61 Grade 2 single cylinder deadbolt is the keyed counterpart in that line.
14) Is the BEST 8T tubular deadbolt tube or the Baldwin deadbolt spacer an alternative to the Square Mountain deadbolt?
No. The Sure-Loc Square Mountain is a complete single cylinder deadbolt with solid brass housing, trim, cylinder and thumbturn. The BEST 8T is a T Series tubular deadbolt tube component, and the Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application - both are parts that go into or alongside a lock rather than a lock you can install on their own.
15) My door has only a half bore on one side - is the Square Mountain deadbolt the right lock?
No. The Sure-Loc Square Mountain is a through-bore deadbolt with a cylinder on one face and a thumbturn on the other, so it needs prep on both sides. For a one-sided opening, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt. For an existing mortise lock body, the Arrow 460 mortise lock strike serves latchbolt and deadbolt functions on a 1-3/4 inch door.
16) I need a deadbolt for a European style mortise door - will the Square Mountain work?
No. The Sure-Loc Square Mountain is a bored deadbolt for standard residential bored door preparation with a 2-3/8 or 2-3/4 inch backset. A European mortise door needs a mortise product such as the Emtek 2050 square European mortise deadbolt with integrated roller latch, or the Emtek 2051 in round trim, both cylinder x thumbturn.
17) Is there a deadbolt with added cylinder tamper protection compared to the Square Mountain?
The Sure-Loc Square Mountain protects the bolt with hardened steel rolling inserts in a cut resistant bolt. If the concern is attack on the cylinder itself, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt in the same cylinder x thumbturn function.
18) What is the Square Mountain deadbolt made of?
Housing is solid brass, with stainless steel substrate components. The bolt is cut resistant and carries hardened steel rolling inserts to resist sawing.
19) What solid brass deadbolt with decorative trim compares to the Sure-Loc Square Mountain?
The Sure-Loc Square Mountain uses a solid brass housing with a cut resistant bolt and hardened steel rolling inserts, offered in Vintage Bronze, Satin Nickel, Flat Black and Satin Brass. For comparable decorative brass-family hardware, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in the Estate Series.
