TownSteel EF3700-48-630 – Frequently Asked Questions

1) Do I need to order the EF3700 by hand, left or right?
No handing to specify. All 3700 Series devices are non-handed or reversible by design, so the same device works on a left or right hand opening. That also makes it easier to stock one part number across a building.
2) Is the TownSteel EF3700 ANSI Grade 1, and is it approved for a barrier free opening?
Grade 1, certified to ANSI/BHMA A156.3, and rated Heavy Duty for commercial use. It also meets the requirements of the Americans with Disabilities Act and the guidelines of the Buy American Act, which matters on federal, school and healthcare specs.
3) What is the closest fire rated narrow stile rim exit device to the TownSteel EF3700 if I need one that also works on a wood door?
The TownSteel EF3700 is a Grade 1 fire rated narrow stile rim exit device, and it is not rated for wood doors. If the opening is a wood door, the Adams Rite 3700 Series 30 inch fire-rated narrow stile rim exit device with starwheel interlocking is the closest match: it is also Grade 1, also narrow stile, also fire rated, and it is listed as wood door compatible. Note the Adams Rite is a 30 inch device against the TownSteel's 48 inch size, so confirm your door width before ordering.
4) What are the alternatives to the EF3700 if I need a fire rated rim device in a different size or brand?
Among fire rated rim devices, Marks USA M9900F is offered in both 36 inch and 48 inch, Arrow FS1250 is a fire rated 32 inch rim device, Orca OED85 Series is a fire rated 36 inch, and the Dexter ED1000 Series has a Grade 1 fire rated rim version. Of those, the EF3700 is the narrow stile one, so if your stile is narrow the others may not have the mounting room.
5) Should I use a rim device like the EF3700 or a concealed vertical rod device?
A rim device latches into a strike on the frame or mullion at the lock edge, so it is the simpler install and the easier retrofit on storefront and hollow metal doors. Concealed vertical rod devices latch top and bottom inside the door and need a door prepped for the rods, but they clean up the look and handle pairs without a center strike. If that is your situation, Hager offers the 4601 Series narrow stile concealed vertical rod device.
6) For a high abuse entrance, is there a heavier narrow stile rim device than the TownSteel EF3700?
The TownSteel EF3700 is a heavy duty Grade 1 narrow stile device with a high shock-resistant latching mechanism intended for vandalism protection. If you want a step up in duty classification, the Detex 40 Advantex is a Grade 1 narrow stile rim device rated extra heavy duty. The difference is the duty class; the EF3700 is the one of the two carried with a fire rating.
7) If I do not need a fire rating, what narrow stile Grade 1 rim devices are alternatives to the TownSteel EF3700?
On a non-rated opening you have several narrow stile Grade 1 choices. The Falcon 1590EO and 1790EO are narrow stile Grade 1 rim devices supplied exit only for 1-3/4 inch doors at 42 inches. The Falcon 19-R is a 36 inch narrow stile Grade 1 exit only device for 1-3/4 inch doors. The Corbin Russwin ED4200 is a 36 inch narrow stile Grade 1 device that accepts trim. The TownSteel EF3700 remains the pick when the door is labeled, since it is the fire rated one.
8) What other fire rated Grade 1 rim exit devices compare to the TownSteel EF3700?
The TownSteel EF3700 is ANSI/BHMA A156.3 Grade 1 certified, UL/cUL listed for UL 305, and fire rated. Among comparable fire rated Grade 1 rim devices, the Dexter ED1000 Series fire rated rim exit device is also Grade 1 and fire rated. If the Grade 1 certification is the deciding line, the Arrow FS1250 32 inch and the Orca OED85 36 inch are fire rated rim devices as well, though they are cataloged without a Grade 1 mark, so specify carefully when the drawing calls out Grade 1.
9) Is a Cal-Royal 5500 48 inch rim device a substitute for the TownSteel EF3700?
Only on a non-rated opening, and the certification level differs. The TownSteel EF3700 is a Grade 1 fire rated heavy duty narrow stile device. The Cal-Royal 5500 is a 48 inch push bar rim device rated heavy duty but listed as Grade 2 and not fire rated. The widths line up; the rating and the fire label do not, so it is not a like-for-like swap where a Grade 1 fire rated device is specified.
10) Is the SDC PSB560 or MSB550 bar an alternative to the TownSteel EF3700?
They solve a different problem. The TownSteel EF3700 is a mechanical Grade 1 fire rated rim exit device with its own latch. The SDC PSB560 SureExit is a 36 inch pressure sense bar with tri-failsafe technology and the SDC MSB550 is a 36 inch mechanical switch bar that releases an electromagnetic lock; both are listed as not fire rated and fit narrow or wide stile doors. They signal a lock to release rather than latching the door themselves, so they are not a swap for the EF3700 on a labeled opening that needs a latching fire exit device.
11) What should I order instead of the TownSteel EF3700 if I want a nightlatch function narrow stile rim device?
The TownSteel EF3700 is a non-handed reversible narrow stile rim device covered for fire rated openings. If the opening needs key-retracted outside entry, the Sargent 8504 is a Grade 1 narrow design rim exit device with a night latch function. The Detex V4003A/03AN is a Grade 1 rim device supplied with night latch trim, though it is a wide stile design.
12) Is a crossbar rim device like the CRL Jackson 1095 an equivalent to the TownSteel EF3700 at 48 inches?
They are both 48 inch rim panic devices, but the CRL Jackson 1095 is a wide stile crossbar exit only device listed as not fire rated, while the TownSteel EF3700 is a narrow stile touchbar style device that is fire rated and ANSI/BHMA Grade 1 certified. The Corbin Russwin ED3200 is another 48 inch wide stile crossbar rim device, Grade 1 for 1-3/4 inch doors and not fire rated. Choose the crossbar styles only where the opening is non-rated and the stile is wide.
13) What finishes does the TownSteel EF3700 come in?
Two finishes: 630 satin stainless steel and 695 Duro (dark bronze tone). Satin stainless is the usual match for aluminum storefront and stainless pulls; 695 suits dark anodized or bronze frames.
