No. All 3700 Series devices are non-handed or reversible, so one part number covers left and right hand openings. That makes it easier to stock a single device across a building.

Not on a labeled opening. Both the Adams Rite 8700 Series and 8800 Series 30 inch devices are Grade 1 narrow stile rim exit devices, but both are listed as not fire rated, where the TownSteel EF3700 is fire rated. They are also 30 inch devices versus the 36 inch EF3700. The Adams Rite 8800 lists a 1-3/4 to 2-1/4 inch door thickness range and is not wood door compatible; the 8700 is wood door compatible. Use them on non-rated narrow stile openings only.

The Adams Rite 3700 Series 30 inch device is the nearest match on the core specs: it is a fire rated, Grade 1, narrow stile rim exit device like the TownSteel EF3700. Two differences to weigh. The Adams Rite 3700 is a 30 inch device where the TownSteel EF3700 covered here is 36 inch, so confirm the bar length suits the door leaf. The Adams Rite 3700 is listed as wood door compatible; the TownSteel EF3700 is not, so on a wood fire door the Adams Rite is the one that fits the application.

The TownSteel EF3700 is a rim device that latches into a strike on the frame or on the inactive leaf. If the opening calls for a concealed vertical rod instead, the Hager 4601 Series 36 inch is a Grade 1 concealed vertical rod narrow stile exit device, and the Hager 4501 is the wide stile pushpad equivalent. Both Hager devices are listed as not fire rated, so on a labeled pair the EF3700, which carries an A label rating on pairs up to 8 by 8 feet, is the rated choice.

It is built for it. The EF3700 is a heavy duty commercial device certified to ANSI/BHMA A156.3 Grade 1, the highest grade for exit hardware, with a high shock-resistant latching mechanism for vandalism protection. Internal components are electro-plated steel or corrosion-resistant alloy.

Yes on both. The EF3700 meets the requirements of the Americans with Disabilities Act and the guidelines of the Buy American Act, which is what procurement usually needs to see on federal and state work.

A rim device like the EF3700 latches into a surface strike on the frame or on a mullion, so it suits a single door or a pair with a center mullion. If you have a pair with no mullion and need clear width through both leaves, a concealed vertical rod device such as the Hager 4601 narrow stile CVR is the type to look at instead. Note the EF3700 does carry an A Label rating on pairs up to 8 by 8 for same or double egress.

The Sargent 8504 is a Grade 1 narrow stile rim exit device in nightlatch function, which gives outside key retraction of the latch. The Corbin Russwin ED4200 is a Grade 1 narrow stile 36 inch rim device that accepts trim. Both are narrow stile like the TownSteel EF3700, but neither is listed as fire rated, so if the opening carries a label the EF3700 is the rated device.

They solve different problems. The TownSteel EF3700 is a mechanical Grade 1 narrow stile rim exit device with a latching mechanism, fire rated and UL/cUL listed to UL 305. The SDC PSB560 is a 36 inch pressure sense bar and the SDC MSB550 is a 36 inch mechanical switch bar that releases an electromagnetic lock; both are listed for narrow or wide stile and both are listed as not fire rated. A switch or sense bar has no latch of its own and relies on a separate locking device, so it is not a substitute for a latching rim device on a rated opening.

The Dexter ED1000 Series is offered in a Grade 1 fire rated rim exit device version, and the Arrow FS1250 is a fire rated 32 inch rim exit device for 1-3/4 inch doors. Both are non-wood-door devices like the TownSteel EF3700. Neither is listed as a narrow stile chassis, so on a 1-3/4 inch minimum stile aluminum leaf the TownSteel EF3700 is the one dimensioned for it.

The TownSteel EF3700 is ANSI/BHMA A156.3 Grade 1 certified, heavy duty, and fire rated. The Cal-Royal 5000 is a 36 inch heavy duty rim exit device with a Grade 2 chassis and is listed as not fire rated; the Cal-Royal 5500 is a 48 inch Grade 2 push bar device, also not fire rated. If your spec calls for Grade 1 on a labeled opening, the EF3700 meets it and the Cal-Royal Grade 2 devices do not.

Two: 630 satin stainless steel and 695 Duro (dark bronze tone). 630 is the usual match for aluminum storefront and stainless pulls; 695 suits bronze anodized frames.

The TownSteel EF3700 is a Grade 1 heavy duty narrow stile rim device with a high shock-resistant latching design for vandalism protection. The Detex 40 Advantex is a narrow stile rim exit device listed at extra heavy duty and Grade 1, which is the step up if the opening sees abuse-level traffic. Note the Detex 40 is not wood door compatible, the same as the EF3700.
