BEST 5108 689 36 – Frequently Asked Questions

1) Will the BEST Precision 5108 rim exit device fit a 2-inch thick metal door?
Yes. The Precision 5108 covers doors from 1-3/4 inches up to 2-1/4 inches thick, so a 2 inch door is inside the range. Openings up to 4 feet wide are covered. One caveat: it is not rated for wood doors, so plan on hollow metal or aluminum.
2) Do I have to specify handing when ordering a Precision 5108 exit device?
No handing to call out. The 5108 is a non-handed rim device, so one part number covers left and right hand openings. For a property manager or distributor stocking spares that means a single shelf item instead of two.
3) Is the BEST Precision 5108 Grade 1, and what is the latchbolt throw?
BHMA certified to ANSI 156.3 Grade 1, with a 3/4 inch throw deadlocking latchbolt in stainless steel. The 3/4 inch throw is the standard commercial rim strike engagement, so it lands in a normal surface-mounted rim strike without special prep. Active case and latchbolt are stainless for corrosion resistance on exterior doors.
4) Can I use a rim exit device like the 5108 on a pair of doors?
A rim device latches into a strike at the edge of the opening, so on a pair you need a removable mullion between the leaves for both doors to latch. If you cannot use a mullion because the full clear opening is required, go to a vertical rod device instead, such as the Hager 4501 Series 36 inch concealed vertical rod with wide stile pushpad, or the narrow stile Hager 4601. Those latch top and bottom and need no mullion.
5) What fire rated rim exit devices compare to the fire rated version of the BEST Precision 5108?
The BEST Precision 5108 is built in fire rated and non fire rated configurations in 36 inch and 48 inch sizes, with the fire rated build excluding dogging. Comparable labeled rim devices include the Dexter ED1000 Series Grade 1 fire rated rim device, the Marks USA M9900F in both 36 inch and 48 inch exit only versions, the Orca OED85 Series 36 inch fire rated rim device, and the Arrow FS1250 fire rated 32 inch rim device. The Marks, Orca and Arrow units are exit only style devices, so if you need keyed lever trim on the outside the 5108 with 808A lever trim covers that.
6) The door is an aluminum storefront with a narrow stile - is the 5108 the right rim device?
The BEST Precision 5108 is a lever-trim rim exit device for commercial hollow metal doors 1-3/4 to 2-1/4 inches thick; it is not a narrow stile device. For a narrow stile aluminum storefront, look at the Adams Rite 8800 Series 30 inch narrow stile rim device, which is Grade 1 and covers the same 1-3/4 to 2-1/4 inch door thickness, or the TownSteel ED3700 36 inch Grade 1 narrow stile rim device. If the storefront opening also needs a fire label, the Adams Rite 3700 Series 30 inch narrow stile device is fire rated.
7) What is a comparable Grade 1 rim exit device with keyed lever trim if the BEST Precision 5108 does not fit the opening?
The BEST Precision 5108 is a Grade 1 rim exit device offered with 808A keyed lever trim or as a device only. If you need a different Grade 1 rim device that accepts trim, the Corbin Russwin ED5200 is a Grade 1 wide stile rim device listed as exit only and accepting trim for 1-3/4 inch doors, and the Corbin Russwin ED4200 is the Grade 1 narrow stile equivalent, also accepting trim on 1-3/4 inch doors. The 5108 covers a wider door thickness range of 1-3/4 to 2-1/4 inches, so on a thicker door the 5108 remains the fit.
8) What looks like a substitute for the BEST Precision 5108 but will not do the same job?
Several rim-mounted bars sit next to the 5108 and do something different. The Detex Advantex 00 Series is a dummy exit device, so it does not latch. The Sargent 12-8810-LTRIM is a fire rated wide stile device also listed with a dummy function. The SDC MSB550 mechanical switch bar and the SDC SureExit PSB560 pressure sense bar are switch bars that release an electromagnetic lock rather than throw a latchbolt, and the Securitron EMB is an electromechanical exit bar. The BEST Precision 5108 is a mechanical rim exit device with a 3/4 inch throw deadlocking latchbolt and keyed lever trim, so none of those are drop-in replacements.
9) Which cylinder prep does the Precision 5108 exit device cover?
The device covers ANSI A115.2 (Type 161) or ANSI A115.18 cylinder lock preparation, which is what most commercial hollow metal doors are already machined for. That is the prep to confirm on the door if you are adding the 808A keyed lever trim rather than ordering the device alone.
10) If I want outside key access on a 5108, what do I order?
Order it with the 808A keyed lever trim. Choosing None (Device Only) gives you an exit-only push-to-exit device with no outside operation at all. The lever trim option is the one to pick for a classroom, office, or any opening where staff need to key in from the outside.
11) Which length of the Precision 5108 do I need for my door width?
Two lengths are built, 36 inch and 48 inch, covering openings up to 4 feet wide. Match the device to the door leaf width: a 3-0 leaf takes the 36 inch, a 4-0 leaf takes the 48 inch. Ordering short leaves the touchbar covering less than the code-required portion of the door width.
12) What is the difference between hex dogging and cylinder dogging on the 5108?
Hex dogging uses a 1/4 turn hex key to hold the touchbar down and keep the latch retracted, which is the standard arrangement and fine for a back-of-house door where only staff carry the wrench. Cylinder dogging swaps that for a keyed cylinder, better where you want the dogging controlled by the same key system as the rest of the building. Less dogging is the choice for fire rated openings, where dogging is not permitted.
13) Is there a lighter-duty alternative if Grade 1 is more than the opening needs?
The BEST Precision 5108 is BHMA certified to ANSI 156.3 Grade 1. Where a Grade 2 chassis is acceptable, the Cal-Royal 5000 is a 36 inch touch bar rim device with a Grade 2 chassis and the Cal-Royal 5500 is a 48 inch push bar rim device, also Grade 2 heavy duty. The Hager 4701 Series 36 inch is a standard duty rim device that still carries Grade 1 BHMA certification. Note that the Cal-Royal 5000 and 5500 are not fire rated, while the 5108 is offered in fire rated and non fire rated builds.
14) Which rim devices handle a 48 inch wide door like the BEST Precision 5108 does?
The BEST Precision 5108 comes in 36 inch and 48 inch device sizes for openings up to 4 feet wide. Other 48 inch class options include the Dexter ED1000 Series 4FT Grade 1 rim device, the Cal-Royal A9820 Series 48 inch exit only device, the Corbin Russwin ED3200 48 inch crossbar rim device, the DORMA 9300 Series 48 inch wide stile device which shares the 1-3/4 to 2-1/4 inch door thickness range, and the Marks USA M9900F 48 inch fire rated device. The Sargent 2828 and 3828 are reversible rim devices specified for 48 inch minimum door width.
15) Which alternatives offer hex key dogging like the BEST Precision 5108?
The BEST Precision 5108 is built with cylinder dogging, hex dogging, or less dogging, with 1/4 turn hex key dogging as the standard arrangement on non fire rated devices. Other rim devices offered with hex key dogging include the Design Hardware 1000R 33 inch heavy duty rim device, the Design Hardware 2000R 33 inch standard duty rim device, and the Stanley Security QED200 Series Grade 1 heavy duty narrow stile rim device. If you want key cylinder dogging rather than a hex wrench, the 5108 cylinder dogging build covers it.
16) For a high-abuse opening, is there a heavier alternative to the BEST Precision 5108?
The BEST Precision 5108 is a Grade 1 device with a stainless steel active case and deadlocking latchbolt and a heavy wrought steel touchbar. If you want a device catalogued above heavy duty, the Detex Advantex 10 Series 36 inch wide stile device and the Detex Advantex 40 Series narrow stile device are both Grade 1 and rated extra heavy duty. The Detex 10 Series is not fire rated, whereas the 5108 is available in a fire rated build.
17) I need a night latch function rather than the keyed lever on the 5108 - what device does that?
The BEST Precision 5108 is supplied with 808A keyed lever trim or as a device only. If the opening calls for a night latch pull instead of a lever, the Sargent 8504 is a Grade 1 narrow design rim exit device with night latch function, and the Detex V4003A/03AN is a Grade 1 wide stile rim device offered with night latch trim.
18) Does the BEST Precision 5108 have a crossbar version, or should I look at another brand?
The BEST Precision 5108 uses a powder coated heavy wrought steel touchbar. For an opening where a crossbar or push bar style is specified to match existing hardware, the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device, and the CRL Jackson 1095 Series 48 inch crossbar rim panic device is a wide stile exit only option. The CRL Jackson 1095P uses a paddle instead of a crossbar.
19) Do I need to specify handing when cross-shopping the BEST Precision 5108 against other rim devices?
The BEST Precision 5108 is a non-handed device, so no field handing determination is required. Several comparable devices are also non-handed or reversible: the CRL Jackson 1295 Series is a non-handed push pad rim panic device for 1-3/4 inch doors, and the Sargent 2828 and Sargent 3828 are Grade 1 reversible rim devices for 48 inch doors. Where a device is handed, you have to confirm the swing before ordering, which is one less step with the 5108.
20) How high off the floor does the Precision 5108 touchbar sit?
Standard touchbar height is 40-5/16 inches from the floor, and it is adjusted during install for proper latching and smooth travel. That figure is worth checking against the other openings in a building if you are trying to keep bar heights consistent across a corridor of doors.
21) What finishes does the BEST Precision 5108 exit device come in?
Two painted finishes: 689 aluminum painted and 695 dark bronze painted. If the rest of a building's exit hardware is on one of those two, the 5108 will blend. Both are applied over a powder coated heavy wrought steel touchbar with a zinc dichromate plated sub-assembly underneath.
