Sargent MD8615E 10BE – Frequently Asked Questions

1) What rail size do I order for a 36 inch wide classroom door with the Sargent MD8615?
Rails come in 32, 36, 42 and 48 inch sizes, so a 36 inch door takes the 36 inch rail. The MD8600 Series is offered in four rail sizes (E, F, J, G) covering door widths from 24 to 48 inches, and rails can be factory cut to the exact door width when you specify it. One thing to watch: if you add the AL alarmed option, the minimum door width is 36 inches.
2) Do I need to specify handing on the Sargent MD8615?
Yes, handing is required. The MD8615 is ordered as either RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always reverse bevel since they swing out of the egress space, so stand outside the door: if the hinges are on your right it's RHR. This differs from some competitors, such as the Von Duprin 8875 and 9875 mortise devices, which are non-handed.
3) What does classroom function mean on the MD8615 exit device?
Classroom function means the outside lever trim is locked or unlocked by key from the outside cylinder, and free egress from the inside is always available by pushing the bar. The lever does not lock from inside the room, so a teacher steps into the corridor to secure the door. The MD8615 is a Grade 1 device, the heaviest commercial rating.
4) Concealed vertical rod or a rim exit device for a pair of classroom doors?
The MD8615 is a concealed vertical rod device, so the rods and the top bolt run inside the door leaf and latch at the head and the sill using the 650 top strike and 606 bottom strike. That secures a pair of doors with no center mullion and leaves nothing exposed for students to grab or vandalize, which is why it gets specified in schools. The trade-off is door prep: the leaf has to be prepped for concealed rods, so it's a specify-at-order item, not a quick retrofit onto a plain door. If your opening already has a mullion or is a single door, a rim device is simpler and cheaper to install and service.
5) Can the Sargent MD8615 be dogged down to hold the door unlatched during school hours?
Yes on non-fire-rated devices. Hex key dogging is standard, and cylinder dogging is available as an option with a #41 cylinder supplied. Fire rated devices cannot be mechanically dogged. If you want the door held unlatched remotely from an office, look at the electric options instead: 56 remote dogging / latch retraction or 58 electric dogging.
6) What are the alternatives to the Sargent MD8615 if my doors are aluminum storefront or I need a fire rating?
The MD8615 is built for hollow metal doors and is a narrow stile device. For aluminum storefront, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device made for aluminum doors, and the Von Duprin 5575 is a Grade 1 narrow stile mortise device that is field reversible. If your opening needs a fire label, neither of those carries one: look at the Adams Rite 3300 Series fire-rated mortise exit device, or the Corbin Russwin ED5600AL, a Grade 1 3-hour fire rated wide stile mortise device that accepts passage or classroom lever trim, though it is rated for 1-3/4 inch doors only.
7) Is a 4 inch stile wide enough for the Sargent MD8615 concealed vertical rod device?
No. The MD8615 needs a minimum stile width of 4-1/2 inches (114mm). At 4 inches you don't have room for the center case and rod housing, so you'd need a true narrow stile device built for a tighter rail, such as the Adams Rite 8400 Series for aluminum doors. Measure the stile on the lock side before you commit the order.
8) Which mortise exit devices look like substitutes for the Sargent MD8615 but will not work on a 2-1/4 inch thick door?
The Sargent MD8615 accommodates door thicknesses from 1-3/4 inches up to 2-1/4 inches. Several comparable mortise exit devices are listed at a 1-3/4 inch door thickness only: the Von Duprin 5575-3ft, the Von Duprin 8875-3FT, the Von Duprin 9875-3FT, the Falcon 25-M-EO-3FT, and the Corbin Russwin ED5600AL. On a thicker door, that thickness figure is the detail to confirm before substituting.
9) I need a mortise exit device for wood doors - can I use the Sargent MD8615?
The Sargent MD8615 is engineered for hollow metal doors. Among comparable mortise exit devices, the Adams Rite 3300 Series and Adams Rite 8300 Series are both described for wood and hollow metal doors, the 3300 being fire rated and the 8300 non fire rated, both Grade 1 wide stile. The Corbin Russwin ED5600AL is also wide stile and Grade 1. By contrast the Von Duprin 8875-3FT, Von Duprin 9875-3FT and Detex 30 Series are listed as not wood door compatible.
10) What mortise exit device should I use on a wide stile door instead of the Sargent MD8615?
The Sargent MD8615 is a narrow stile device requiring a 4-1/2 inch minimum stile width. For wide stile openings, Grade 1 wide stile mortise exit devices include the Von Duprin 8875-3FT crossbar device at 36 inches, non-handed, 1-3/4 inch door thickness, non fire rated; the Von Duprin 9875-3FT smooth case device at 3 ft, non-handed, 1-3/4 inch door thickness; and the Von Duprin 9475/9575 Impact Series, which uses a recessed push pad. The 8875 and 9875 are not wood door compatible.
11) What mounting height should the MD8615 push bar be installed at in an elementary school?
Use the 38 inch (965mm) centerline for elementary schools and accessibility-driven applications. The standard commercial centerline is 41 inches (1041mm). Decide before you prep the door, since the strike and rod locations follow the centerline.
12) How much does the Sargent MD8615 push bar stick out into the corridor?
Projection is 3 inches at neutral and 2-1/8 inches when the bar is fully depressed. The center case measures 8-3/8 x 2-5/8 inches. Those numbers matter when the door swings into a narrow corridor or up against a return wall, and when you're checking clearance to a door closer arm.
13) What lever trim options come with the Sargent MD8615 and can I order the device without trim?
Eight ET lever trims are offered: A, B, E, F, J, L, P and W levers. You can also order the device alone with no trim, which is what you want when the outside face is exit only or you're reusing existing trim. For a classroom application you generally need a lever trim with a cylinder, since that is what the key controls.
14) If I do not need classroom lever trim, is there a simpler mortise exit device than the Sargent MD8615?
Yes. The Sargent MD8615 is a classroom function device and can be ordered with ET lever trim in A, B, E, F, J, L, P or W lever styles, or as exit device only. If the opening never needs outside key access, exit only mortise devices include the BEST Precision 2301 Series with heavy wrought construction, the Falcon 25-M-EO in a 36 inch wide stile 3 ft size with 1-3/4 inch door thickness and Grade 1 rating, and the Detex 30 Series Advantex Grade 1 wide stile device, which is supplied device only and is not wood door compatible.
15) Is the Sargent MD8615 a Grade 1 device like the Von Duprin and Adams Rite mortise exit devices?
Yes. The Sargent MD8615 is rated Grade 1 for commercial use, as are the Von Duprin 5575, 8875, 9875 and 9475/9575, the Adams Rite 3300, 8300 and 8400 Series, the Corbin Russwin ED5600AL, the Falcon 25-M-EO and the Detex 30 Series Advantex. Differences among them come down to stile type, fire rating, handing, and whether lever trim is included, rather than to the ANSI grade.
16) What finishes does the Sargent MD8615 come in for matching existing school hardware?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black suede powder coat and WSP white suede powder coat. 32D satin stainless is the usual match for institutional openings; the powder coats are the ones to use when you're matching painted storefront or dark frames.
