BEST FL5203 689 48 – Frequently Asked Questions

1) Will the BEST Precision 5203 fit a 2-inch thick door?
Yes. The Precision 5203 surface vertical rod device covers doors from 1-3/4 inches up to 2-1/4 inches thick, so a 2 inch door is inside the range. Most competing surface vertical rod devices are built for 1-3/4 inch only, so this is one of the few that handles a thicker leaf without special ordering.
2) Can I dog down a fire rated exit device like the 5203?
Mechanical dogging is not permitted on a fire rated opening, which is why Less Dogging is one of the choices when you order the 5203. Hex dogging and cylinder dogging are also offered on this device, so if you are putting it on a non-rated opening and want the latches held retracted during business hours, pick one of those instead of Less Dogging.
3) Will the 5203 latch into my existing strikes?
The device comes with its own strikes and they need to be used: a No. S300 investment cast stainless steel top strike and a No. S460 steel bottom strike in black powder coat. The top latchbolt is deadlocking stainless with a 3/4 inch throw and the bottom bolt is steel with a 5/8 inch throw, adjustable for up to a 3/4 inch door undercut. Plan on new head and threshold prep unless the existing strikes were the same Precision parts.
4) Does the 5203 need a mullion on a pair of doors?
No. A surface vertical rod device latches into the frame head and the floor or threshold, so a pair of 5203 devices secures both leaves with no center mullion and keeps the full clear opening. If you would rather latch into a mullion, you want a rim device plus a removable mullion instead, which is a different product entirely.
5) What door prep does the Precision 5203 require?
Templates are supplied for ANSI A115.2 (Type 161) or ANSI A115.18 cylinder lock prep. If the door is already machined to ANSI A115.18, the active case through bolts drop into that prep with no additional machining, which is the detail that saves a retrofit crew from re-routing a door.
6) What other fire rated surface vertical rod exit devices can replace a BEST Precision 5203 on a fire door assembly?
The BEST Precision 5203 is UL Listed Panic and Fire Exit Hardware with ANSI/BHMA Grade 1 certification for doors up to 4'-0" wide. Fire rated surface vertical rod alternates include the TownSteel EF9727, a fire rated heavy duty Grade 1 wide stile device for 36" x 84" openings that is also wood door compatible; the Adams Rite 3100 Series in 30", a fire rated Grade 1 wide stile device for 1-3/4" doors; the Arrow S1150 in 30", fire rated and offered as device only less trim for narrow or wide stile; and the Sargent 2727, a Grade 1 fire rated reversible exit only device on a wide stile. Match the device length to your actual door width before ordering.
7) Is a Von Duprin 2227 or Falcon 25-V a direct substitute for the BEST Precision 5203?
No. The BEST Precision 5203 is UL Listed Panic and Fire Exit Hardware, so it can go on a labeled fire door. The Von Duprin 2227-3FT is a Grade 1 wide stile surface vertical rod device for 36" doors listed as not fire rated, and the Falcon 25-V-EO is a Grade 1 wide stile exit only device at 3 ft, also listed as not fire rated. Both are legitimate wide stile vertical rod devices for non-rated egress openings, but neither carries the fire rating the 5203 does.
8) I need a vertical rod device with key access from outside, not just exit only. What are my options besides the BEST 5203?
The BEST Precision 5203 is a key retracts latchbolt device and can be ordered with 603 keyed trim or 703A keyed handle trim, or as device only. If you want another device that accepts outside trim, the Corbin Russwin ED5400 is a Grade 1 wide stile surface vertical rod device listed as exit only, accepts trim, the ED4400 is the narrow stile equivalent that accepts trim, and the ED7000 Series ED7400 is a narrow stile crossbar device that accepts operator trim. All three Corbin Russwin models are listed for 1-3/4" doors and are not fire rated, so they suit non-rated openings only.
9) Does a Sargent 12-8710 do the same job as the BEST Precision 5203?
No. The BEST Precision 5203 is a key retracts latchbolt fire rated device with a stainless steel deadlocking top latchbolt and a steel bottom bolt that actually latch the opening. The Sargent 12-8710 is a Grade 1 wide stile surface vertical rod device in the 8700 Series with a dummy function, meaning it provides the matching push appearance without active latching. Use the dummy only on the inactive leaf or where no latching is required.
10) Do I need to order a right hand or left hand 5203?
No handing to specify. The 5203 is field reversible for all functions and trims, and it ships packaged right hand reverse bevel. A locksmith can flip it on site, so one part number covers both leaves of a pair.
11) What does the key retracts latchbolt function on the 5203 actually do?
Turning the key pulls both latchbolts back so the door can be pushed or pulled open from the outside, and pushing the touchbar always releases from the inside. It is the function you want on an exit door that staff also need to enter through with a key, rather than an exit-only device like the Arrow S1150 or the Falcon 25-V-EO, which give you egress only with no outside operation.
12) Which outside trim should I order with the Precision 5203?
Three choices: 603 keyed trim, 703A keyed handle trim, or no trim at all if you are ordering the device only. Take the 703A handle trim where people need to pull the door open after unlocking it, and the 603 where a key cylinder in a plate is enough. Device only makes sense when you already have matching trim on the opening.
13) Can I run the 5203 without a bottom rod?
Yes, a less bottom rod version is available. LBR removes the bottom rod and bolt so nothing runs down to the threshold, which cuts the damage and dirt problems on high-traffic and exterior doors. On a fire rated opening confirm your assembly listing allows LBR, since removing the bottom latch changes how the pair is secured. The Orca OED56 is another surface vertical rod we carry configured less bottom rod, though it is not fire rated.
14) The BEST Precision 5203 is a wide device for a 48 inch door. What should I use on a narrow stile aluminum storefront instead?
The BEST Precision 5203 is a surface vertical rod device sized for openings up to 4'-0" wide by 10'-0" high on 1-3/4" to 2-1/4" doors. For narrow stile aluminum openings, narrow stile surface vertical rod devices include the Von Duprin 3327A in 36" with a grooved case, the Von Duprin 7527 in 3 ft, the Falcon 19-V-EO in 36" exit only, and the TownSteel ED3727 for 36" x 84". Those four are listed as non fire rated, so confirm your opening does not carry a fire label.
15) What is a lighter duty vertical rod exit device if I do not need the Grade 1 fire rated BEST 5203?
For a non-rated interior opening where Grade 1 fire exit hardware is more than the job needs, lighter alternatives include the Design Hardware 2000V in 33", a standard duty surface vertical rod device; the Orca Hardware OED56 in 36", a standard duty exit only device supplied less bottom rod in aluminum finish and non-handed; the Dexter ED2000 Series, a Grade 2 surface vertical rod panic device; and the TownSteel TS5100 in 36" x 84", a heavy duty Grade 2 device. All are listed as non fire rated, unlike the BEST Precision 5203.
16) I want a less bottom rod vertical rod device for a hospital corridor. How does the BEST 5203 compare to other LBR options?
The BEST Precision 5203 can be ordered with the less bottom rod option on any of its finish, dogging and trim combinations, including hex dogging, cylinder dogging or less dogging in 689 aluminum painted or 695 dark bronze painted. The Orca Hardware OED56 in 36" is also supplied less bottom rod, in aluminum finish and non-handed, though it is a standard duty exit only device that is not fire rated. If the corridor door is fire labeled, the 5203 is the one of the two that carries UL fire exit hardware listing.
17) If I am standardizing a wood door school on Grade 1 vertical rod hardware, what compares to the BEST Precision 5203?
The BEST Precision 5203 is a Grade 1, UL Listed fire exit hardware device for 1-3/4" to 2-1/4" doors up to 4'-0" wide. For wood doors, TownSteel lists wood door compatibility on the EF9727, a fire rated Grade 1 heavy duty wide stile device for 36" x 84", and on the non-rated ED8927 Grade 1 wide stile and ED3727 Grade 1 narrow stile, both 36" x 84". By contrast the Von Duprin 7527 and 7827 are listed as not wood door compatible, so they are not the choice for a wood leaf.
18) Which vertical rod devices offer hex key dogging like the BEST Precision 5203?
The BEST Precision 5203 can be ordered with hex dogging, cylinder dogging, or less dogging. Among comparable wide stile devices, the Von Duprin 7827 in 3 ft is a Grade 1 surface vertical rod device supplied with hex key dogging for 1-3/4" doors; it is listed as not fire rated. Note that on a fire rated opening mechanical dogging is generally not permitted, which is why the less dogging build of the 5203 exists.
19) How high off the floor does the 5203 touchbar sit?
Standard touchbar centerline is 40-5/16 inches from the floor, and custom heights are available when you need to line up with existing devices on adjacent openings. For a property manager standardizing a building, that standard height is what keeps a run of doors looking consistent.
20) What finishes does the Precision 5203 come in?
Two painted finishes: 689 aluminum and 695 dark bronze. Both are available with any of the trim and dogging combinations, so you can match aluminum storefront or bronze anodized entrances across a building without changing device type.
21) Is the Precision 5203 built for high traffic entrances?
It is a commercial device carrying ANSI/BHMA Grade 1, which is the heaviest duty level in the standard. Construction is zinc dichromate plated heavy wrought steel active case with a powder coated heavy wrought steel touchbar, and the top latchbolt is stainless. That is the build you want on school, retail, and healthcare exits that cycle all day.
