BEST 8TD2B626 – Frequently Asked Questions

1) What backsets does the BEST 8T T Series deadbolt tube come in?
Two: 2-3/8 inch and 2-3/4 inch. That is the measurement from the door edge to the center of the bolt bore, and it has to match the hole already drilled in the door. Residential and light commercial doors are usually prepped 2-3/8 inch; wider commercial stiles are usually 2-3/4 inch. Measure the existing prep before you pick, because the 8T tube is not an adjustable-backset unit like the Brinks Raleigh or Mendocino deadbolts, which use a 4-way adjustable backset to cover both.
2) Is the BEST 8T deadbolt tube a complete lock or just the bolt assembly?
It is the tube (bolt) component of a T Series tubular deadbolt, not a finished lock. It carries the bolt into the cross bore and supports the stainless steel bolt with a full 1 inch throw. You still need the T Series trim for the outside and inside, and the SFIC core, to end up with a working deadbolt on the door. Buyers who want a lock that arrives complete should look at a full deadbolt like the Arrow E61 SFIC-prep deadlock, which ships as a deadlock less core.
3) Will the 8T tube take my existing BEST SFIC cores and stay on my masterkey system?
Yes. The 8T tube is built for Small Format Interchangeable Cores and drops into an existing SFIC masterkey system, and BEST states it works with other manufacturers' SFIC cores too. That means a facility already keyed on a BEST small format system can rekey the opening by pulling the core with a control key rather than pulling the lock off the door.
4) What is the closest complete SFIC deadbolt to a BEST T Series tubular deadbolt if I need the whole lock rather than the bolt tube?
Two complete deadbolts in the same small-format-interchangeable-core direction are the Arrow E61, a Grade 2 single cylinder deadlock supplied with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC, a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset. The BEST 8T tube is the bolt assembly of a T Series tubular deadbolt, sold in 2-3/8 inch and 2-3/4 inch backsets, and it accepts small format interchangeable cores so it drops into an existing SFIC masterkey system. If your keying is already SFIC, the Arrow E61 matches on core format and door thickness range, while the Deltana CL200LAIC matches the 2-3/4 inch backset.
5) I key everything in Schlage C, not SFIC. What deadbolt should I buy instead of a BEST T Series?
The BEST 8T tube is built around small format interchangeable cores, so a conventional-keyway house has less reason to specify it. The Hager 3215 is a single cylinder commercial deadbolt with a 1 inch throw in a Schlage C keyway, fire rated, for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3214 is the double cylinder version in the same keyway and door range. Both carry the same 1 inch bolt throw the BEST T Series bolt provides, so the security projection is unchanged; only the cylinder format differs.
6) The door is thicker than 1-3/4 inch. What deadbolt works there?
For a thicker leaf, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock in a cylinder by blank configuration rated for 1-3/4 inch to 2-1/4 inch doors, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt covering 1-3/8 inch to 2 inch. The Corbin Russwin DL3011 is the one to look at when the opening is a heavy commercial door and the blank inside face is acceptable; the Deltana 7312KA2 keys both sides.
7) Is a Baldwin 8BR0618001 deadbolt spacer a substitute for a BEST 8T tube?
No. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, a fitting piece rather than the bolt mechanism. The BEST 8T is the deadbolt tube itself, the field-reversible bolt assembly that carries the solid stainless steel bolt with a full 1 inch throw in a T Series tubular deadbolt. If what you actually need is the working bolt, the spacer will not do it; if you need a complete Baldwin double cylinder lock, the Baldwin Reserve Contemporary Round or Contemporary Square double cylinder deadbolts are the whole assemblies.
8) Does the BEST 8T deadbolt tube need to be ordered left hand or right hand?
Handing does not apply. The 8T is nonhanded and field reversible, so one part covers both swings and you do not have to know which way the door hangs when you order. That matters for a property manager stocking spares across a building: one tube per backset per finish covers every opening.
9) Will a BEST 8T deadbolt with a 1 inch throw latch into a standard commercial strike?
The bolt is solid stainless with a full 1 inch throw, which is the projection commercial strike and frame preps are cut for, so it reaches into a standard deadbolt strike box on a normally aligned frame. If the frame is racked or the strike is shallow, the extra length is what buys you tolerance. The Hager 3215 single cylinder deadbolt is another 1 inch throw commercial option if you want a complete keyed unit instead of the tube.
10) I want a deadbolt with a thumbturn on the inside instead of a keyed core, what should I buy?
The 8T tube is part of a keyed SFIC deadbolt, so it is the wrong starting point for a cylinder-by-thumbturn opening. For that, a complete single cylinder deadbolt is the simpler buy: the Accentra D111 is Grade 1, cylinder by thumbturn, 2-3/8 inch backset, and rated for 1-3/8 to 1-3/4 inch doors. If you want a thumbturn on an SFIC system, the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset.
11) Is a tubular deadbolt like the BEST 8T the right choice, or do I need a mortise deadlock?
A tubular deadbolt goes into a bored cross bore and edge bore, which is the prep most wood and hollow metal doors already have, so it is the faster install and the easier retrofit. A mortise deadlock needs a pocket routed into the door edge, and that is the route to take when the door is already mortise-prepped or you want a small case unit like the Dormakaba D900 mortise deadbolt. For a narrow one-sided application with no inside trim, the Callan 205S is a one-sided half-bore deadbolt instead.
12) I need a deadbolt keyed on both sides of the door instead of a thumbturn inside. What are my options?
Double cylinder alternatives include the Design Hardware D1 Series, a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors, the Dexter DB1000 double cylinder, Grade 1 for 1-3/8 inch to 1-7/8 inch doors, and the Hager 3214 double cylinder with a Schlage C keyway for 1-3/8 inch to 1-3/4 inch. Check your local egress code before specifying any of them, since a keyed inside cylinder removes the free-turn release.
13) What do I use on the exit side of a door where no key is wanted at all?
The Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on the outside and a thumbturn on the inside, for 1-3/8 inch to 1-3/4 inch doors. The Callan 205S is a Grade 3 one-sided half-bore deadbolt for openings that only need throwing from one face. Both differ from the BEST 8T approach, which is built to take a small format interchangeable core so the bolt sits in a keyed masterkey system.
14) What is the difference between a classroom deadbolt and a standard commercial deadbolt when I am specifying for a school?
A classroom deadbolt is keyed on the outside and blank or non-operating inside, so the bolt cannot be thrown from within the room. The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, the Falcon D211 is the Grade 2 medium duty version, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors. A BEST T Series tubular deadbolt is ordered by fixed backset, 2-3/8 inch or 2-3/4 inch, so on a mixed-prep building the adjustable-backset Falcon units cover both bores from one part number.
15) We want to stop issuing keys on these doors. What electronic deadbolt replaces a keyed tubular deadbolt?
The Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the CL2210 is the electronic mortise deadbolt version. 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 an electronic lock override. Note that the surface-mounted Codelocks CL2200 and the mortise CL2210 need different door prep than a bored tubular deadbolt, so confirm the existing bore before committing.
16) Is an Arrow 460 strike an alternative to a BEST 8T tube?
No. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, sized for 1-3/4 inch doors. It is the frame-side piece the bolt lands in, not the bolt itself. The BEST 8T is the tube that carries the bolt in the door leaf. The two are complementary parts of an opening, not interchangeable, and a mortise strike is prepped for a mortise case rather than a bored tubular deadbolt.
17) What finishes can I get the BEST 8T deadbolt tube in, and can I match the other doors in my building?
Seven finishes, in both backsets: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Those are BHMA finish codes, so if the existing hardware on your other openings is marked 626, ordering 626 here keeps the run consistent without holding a sample up to it.
18) Can I get the BEST 8T with tamper-resistant mounting for an exposed or exterior door?
Yes, as options. The 8T tube accepts concealed mounting screws and a free-turning tapered cylinder ring, which is what stops someone attacking the screws or wrenching the cylinder from the pull side. If you would rather buy the protection built into a finished lock, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard.
19) What is a simpler single cylinder deadbolt if I do not need interchangeable core keying?
For straight cylinder by thumbturn service without core interchange, the Dexter DB2000 is a Grade 2 single cylinder deadbolt for 1-3/8 inch to 1-3/4 inch doors, the Cal-Royal CB160 is a Grade 2 single cylinder with a tamper-resistant cylinder guard, and the Arrow DBX61 is a Grade 2 single cylinder deadbolt. If you want Grade 1 in the same simple format, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch and the Deltana CL200LM is a Grade 1 cylinder by thumbturn.
20) The finish has to match brass or bronze trim on the rest of the building. Which deadbolts cover that?
A BEST 8T tube is offered in bright brass 605, satin brass 606, bright bronze 611, satin bronze 612, oil-rubbed satin bronze 613, bright chrome 625 and satin chrome 626. If the look is decorative rather than commercial, the Emtek 11 Tuscany is a lost wax cast bronze deadbolt in cylinder by thumbturn, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt. Those are styled entry products, so match the function first and the finish second.
