BEST 2608 630 36 – Frequently Asked Questions

1) Will the 2608 exit device work on a pair of doors with no center mullion?
Yes. Being a concealed vertical rod device, the 2608 latches at the head and at the threshold rather than into a strike on the jamb, so a pair of doors can be secured without a center mullion. The top latchbolt is a deadlocking stainless steel bolt with 3/4 inch throw and the bottom bolt is independent with 5/8 inch throw, so each leaf holds top and bottom on its own.
2) Do I have to specify handing when ordering the BEST Precision 2608?
The device itself is non-handed, so the same 2608 chassis works either way. Handing only comes into it when you add lever trim: if you pick one of the 2908 lever trims you must call out RHR (right hand reverse) or LHR (left hand reverse). Order it as device only and there is no handing to specify.
3) What is the LBR less bottom rod option on a concealed vertical rod exit device, and when should I order it?
Less bottom rod deletes the bottom rod and bolt, so the door latches only at the head. Trades pick it where the floor is uneven, where carpet or a threshold fouls the bottom strike, or where a bottom bolt would be a trip and maintenance headache. The 2608 is ordered LBR yes or no as a required choice. Keep in mind LBR removes the 5/8 inch throw bottom bolt from the door's securing, so the top latch is doing all the work.
4) Can I get the Precision 2608 exit device fire rated for a labeled opening?
Yes, the 2608 is ordered either non-rated or fire rated, and it's UL Listed for panic and fire exit hardware with ANSI/BHMA Grade 1 certification. One catch that matters on a fire door: dogging is not available on fire exit hardware, so a fire rated 2608 cannot be held dogged down for daytime free access.
5) What size 2608 exit device do I order for a 36 inch door versus a 42 inch door?
The 2608 comes in 36 inch and 48 inch device lengths, covering doors up to 4 feet wide. A 36 inch door takes the 36 inch device; anything wider than that, up through the 4 foot maximum, takes the 48 inch. Door height is covered up to 10 feet.
6) Does the 2608 exit device come with outside lever trim or do I order that separately?
Trim is a separate choice on the order. You can take the 2608 as device only, which leaves the outside as exit only with no outside operation, or add one of four lever trims: 2908A, 2908B, 2908C, or 2908D. Pick a lever trim and you also have to declare handing, RHR or LHR.
7) What concealed vertical rod device matches the Precision 2608 for an aluminum storefront door?
For aluminum storefront the device has to be a narrow stile build. The Precision 2608 is a narrow stile concealed vertical rod device offered in finishes including 628 Satin Aluminum, 630 Satin Stainless Steel and 690 Statuary Dark Bronze for storefront coordination. The Adams Rite 8600 is a Grade 1 narrow stile concealed vertical rod device specifically for aluminum doors. The Adams Rite 8500 by contrast is a wide stile device for hollow metal doors and will not suit a storefront stile.
8) What is the closest narrow stile concealed vertical rod equivalent to the BEST Precision 2608 from another manufacturer?
The Precision 2608 is a narrow stile concealed vertical rod exit device with ANSI/BHMA Grade 1 certification for 1-3/4 inch thick doors. The Corbin Russwin ED4800 is the nearest match in kind: it is a Grade 1 narrow stile concealed vertical rod device for 1-3/4 inch doors, and like the 2608 it accepts trim rather than being exit only. The Dormakaba 9600BB is also a Grade 1 narrow stile concealed vertical rod device, with a door thickness range of 1-3/4 inch to 2-1/4 inch and a pushpad rather than a lever-trim-ready chassis. Confirm trim function before ordering either as a swap.
9) Which concealed vertical rod devices are fire rated if the Precision 2608 is ordered non-rated?
The Precision 2608 is ordered with a Rating selection of either Non-Rated or Fire Rated, so the fire door version comes off the same series. If a different make is needed for a fire opening, the Adams Rite 3600 and Adams Rite 3900 are Grade 1 fire rated concealed vertical rod devices for wide stile, with the 3900 carrying a 1-1/2 hour rating. The Sargent 12-MD8613 is a Grade 1 fire rated wide stile concealed vertical rod device in classroom function. Note that on the 2608 the hex key dogging that is standard on the non-rated build is not available on fire exit hardware.
10) The opening does not need lever trim, just a code-compliant exit. What is a simpler concealed vertical rod device than the Precision 2608?
The 2608 is built to take lever trim, with 2908A, 2908B, 2908C and 2908D lever trim options plus a device-only configuration. When the door is push-to-exit only and no outside operation is wanted, an exit only device removes that side of the decision entirely. The Falcon 1690EO is a Grade 1 narrow stile concealed vertical rod device in exit only function for 1-3/4 inch doors, and the Falcon 24-C is a Grade 1 narrow stile concealed vertical rod exit only device in a 36 inch size. The Von Duprin 3347A-EO is another Grade 1 narrow stile exit only option and is supplied less bottom rod.
11) Can the BEST Precision 2608 be used on a wide stile hollow metal door?
The 2608 is a narrow stile concealed vertical rod device, so a wide stile opening calls for a device built for that stile. The Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors that accepts trim. The Adams Rite 8500 is a Grade 1 wide stile concealed vertical rod device for hollow metal doors, and the Dormakaba 9100 is a heavy duty Grade 1 wide stile pushpad device covering 1-3/4 inch to 2-1/4 inch doors. The CRL Jackson 1285 is listed for narrow, medium or wide stile.
12) Is the Falcon 1491DT a substitute for the BEST Precision 2608 on the inactive leaf of a pair?
It is not an operating device. The Falcon 1491DT is a dummy function narrow stile concealed vertical rod trim for 1-3/4 inch doors supplied with a 9970 pull, so it gives the matching appearance without a working latch. The Precision 2608 is a functioning panic device with a stainless steel deadlocking top latchbolt at 3/4 inch throw and an independent bottom bolt at 5/8 inch throw. Use the 1491DT only where the leaf is not required to latch or to serve as an egress door.
13) Does the BEST Precision 2608 come with dogging, and can I get keyed cylinder dogging?
Standard is 1/4 turn hex key dogging. Cylinder dogging and less dogging are both orderable instead, so a facility that wants the door dogged open only by an authorized keyholder can specify cylinder dogging on a non-rated device. On a fire rated 2608 there is no dogging at all.
14) How do I adjust the latches on a concealed vertical rod device after the door is hung?
On the 2608 the top and bottom latch adjustors lock in place and are reachable through the door after installation, so you can dial in latching without pulling the device off or taking the door down. That matters on concealed rod devices, where the rods are inside the stile and a building that settles will otherwise leave you chasing a door that won't latch at the head.
15) What finishes does the BEST Precision 2608 exit device come in for matching existing hardware in a building?
Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed satin bronze, 622 matte black, 625 bright chrome, 626W satin chrome weatherized, 628 satin aluminum, 630 satin stainless, and 690 statuary dark bronze. For a fleet of aluminum storefront entrances, 628 and 630 are the usual matches. 626W is the weatherized finish for exterior openings, and it pairs sensibly with the WTS or WTDS weatherized touchbar switches.
16) Will the Precision 2608 exit device hold up on a high traffic school or hospital entrance?
It's a commercial device with ANSI/BHMA Grade 1 certification, the highest of the three ANSI grades for cycle and strength performance, and the side filler and end cap are heavy wrought brass, bronze, or stainless steel with investment cast steel chassis components. Grade 1 is what specifiers write for education, healthcare, and high traffic institutional openings.
17) Should I use a concealed vertical rod device or a surface vertical rod on my storefront doors?
Concealed rods, like the 2608 uses, run inside the door stile: nothing exposed to catch a cart or a hand, and a cleaner look on a glass front entrance, but the door has to be prepped for concealed rods, which generally means specifying it that way from the door manufacturer. Surface rods bolt to the face of the door and are the practical choice when you're retrofitting an existing door that was never prepped for concealed hardware. If the door is already prepped for concealed rods, the 2608 drops into that prep for 1-3/4 inch narrow stile doors up to 4 feet wide.
18) Will the BEST Precision 2608 work on a wood door?
The Precision 2608 is specified for 1-3/4 inch thick doors up to 4 feet 0 inches wide by 10 feet 0 inches high, with lock-in-place top and bottom latch adjustors reachable through the door after installation. Among comparable narrow stile devices, the Von Duprin 7547 is a Grade 1 narrow stile concealed vertical rod device for 1-3/4 inch doors that is not wood door compatible, so on a wood leaf verify the specific device against the door construction rather than assuming a narrow stile device carries over.
19) What is the difference between the BEST Precision 2608 and a crossbar concealed vertical rod device like the Von Duprin 5547?
The 2608 is a touchbar style narrow stile concealed vertical rod device offered with touchbar monitoring switch options such as TS and TDS. The Von Duprin 5547 is a Grade 1 narrow stile concealed vertical rod device with a crossbar actuator for 1-3/4 inch doors, and the Corbin Russwin ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device, also 1-3/4 inch, that accepts operator trim. Crossbar and touchbar devices present a different look and a different push surface, so matching the rest of the openings in a building usually decides which one goes on the door.
20) A 42 inch or 44 inch door leaf needs a concealed vertical rod device. Does the Precision 2608 cover it?
The Precision 2608 is furnished in 36 inch and 48 inch sizes and is specified for doors up to 4 feet 0 inches wide by 10 feet 0 inches high at 1-3/4 inch thickness, so a 42 or 44 inch leaf falls inside that width range on the 48 inch device. Among other makes, the Falcon 1990EO is a Grade 1 narrow stile concealed vertical rod exit only device in a 44 inch size, and the Von Duprin 3347A is a Grade 1 narrow stile device in a 36 inch size for 1-3/4 inch doors.
21) Which concealed vertical rod device should be specified when the exterior side needs a lever rather than a pull?
The Precision 2608 takes 2908A, 2908B, 2908C or 2908D lever trim, with handing specified as RHR or LHR when lever trim is chosen, and the device itself is non-handed. The Sargent MD8613F-LTRIM is a heavy duty Grade 1 concealed vertical rod device supplied with lever trim for a 36 inch by 84 inch metal door and hex dogging. The Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod device that accepts trim, so outside trim is ordered as a separate selection.
22) How does cylinder dogging on the Precision 2608 compare with hex dogging on other concealed vertical rod devices?
The Precision 2608 is offered with cylinder dogging, hex dogging as standard, or less dogging, and the standard hex dogging uses a 1/4 turn hex key. The Sargent MD8613F-LTRIM is a Grade 1 concealed vertical rod device supplied with hex dogging. Cylinder dogging puts the dogging under key control so only a keyholder can hold the latch retracted, while hex dogging is worked with the hex wrench; less dogging is the choice where the device must always latch, as on fire exit hardware.
23) Is a CRL Jackson 1085 an equivalent to the BEST Precision 2608?
They fill different roles. The CRL Jackson 1085 is a 48 inch non-handed concealed vertical rod panic device in exit only function for wide stile, so it has no outside operation and is built for a wide stile leaf. The Precision 2608 is a narrow stile device that is non-handed but accepts 2908 series lever trim for outside operation. Where an exit only device is acceptable but the leaf is narrow stile, the CRL Jackson 1285 is exit only and covers narrow, medium or wide stile.
