Sargent 351-UO TB EN – Frequently Asked Questions

1) Does the Sargent 351 Powerglide closer need to be ordered handed for a left or right hand door?
No handing to specify. The 351 Powerglide closer body is non-handed and works in all applications, and the forged steel arms are interchangeable. You pick the mounting position (standard, top jamb, parallel, or track) at install rather than ordering a hand.
2) Will the Sargent 351 closer work on a fire-rated door?
Yes. The 351 Series is UL Listed and cUL Listed to Canadian safety standards, with UL10C and UBC positive pressure fire test compliance, so it can go on fire-rated openings. Note that a hold-open arm is not appropriate on a fire door; this model ships with the universal standard arm, which is the non-hold-open type.
3) What spring size does the Sargent 351 come set to, and can I change it in the field?
It arrives factory set at size 3 and adjusts across sizes 1 through 6, so one closer covers light interior doors up to heavy exterior ones. Set the power to suit the door width and weight, then verify opening force still meets ADA on accessible openings; the 351 is built to meet ADA requirements.
4) What does the TB in Sargent 351-UO TB EN mean, and when do I need it?
TB is thru bolt mounting. Instead of relying on sheet metal or wood screws into the door face, the closer is fastened with bolts that pass all the way through the door. That is what you want on hollow metal doors with thin face sheets, aluminum doors, and abused high-traffic openings where screws pull out. The EN is the sprayed aluminum enamel finish.
5) Can I use this Sargent arm on a 1431 or 281 Series closer body?
Yes. The forged steel arms are interchangeable across the Sargent 351, 1431, and 281 Series, so the universal standard arm suits any of those bodies. That makes it a practical stock item if a building has a mix of those three Sargent series on the doors.
6) I need the door to stay open at a set position - is the Sargent 351 standard arm the right choice?
The Sargent 351-UO TB EN uses a universal standard arm, which is a regular closing arm with no hold-open detent. For an opening that needs to stand open, a hold-open arm assembly is the correct part: the LCN 1250-3049/PA is a non-handed hold-open arm with a parallel arm shoe and adjustable hold-open, the LCN 4010-3049 is a hold-open arm with an adjustable elbow, and the Falcon SC70A-3049/PA is a hold-open arm with a PA bracket. Each of those is built for its own closer series, so select the hold-open arm that matches the closer body on the door. Hold-open is also generally not permitted on a fire-rated opening without a listed release device.
7) What is the closest equivalent to a Sargent 351 universal standard arm from another closer brand?
The Sargent 351-UO TB EN ships with a universal standard arm on a surface closer body. The nearest like-for-like arm component from another line is the LCN 4000T-3077T standard arm replacement component, which is also a standard (regular) arm rather than a hold-open or parallel-only assembly. Note that closer arms are matched to their own closer body - the LCN 4000T part is built for the LCN 4000T Series, while the Sargent forged steel arms interchange across the Sargent 351, 1431, and 281 Series. Match the arm to the closer body already on the door.
8) My opening is a center hung door on a floor pivot - can I use the Sargent 351?
The Sargent 351-UO TB EN is a surface-mounted closer with a universal standard arm, supporting standard, top jamb, parallel, and track installations on the door face or frame. It is not a center hung pivot assembly. For a center hung door running on a floor pivot, the Falcon OHC100A-DP is a center hung floor pivot with end load arm intended for the OHC100 Series overhead concealed closers. Those are two different opening types, so confirm how the door is hung before ordering.
9) Is a standard arm or a parallel arm right for my opening?
The universal standard (regular) arm mounts on the pull side of the door with the arm projecting into the opening, and it gives the most efficient closing power. Use parallel arm mounting instead when the door swings out into a corridor, when you need the arm tucked up against the door face to stay out of traffic, or when the pull side has no room. This closer supports standard, top jamb, parallel, and track mounting, so the body does not change; the mounting does.
10) Is the Sargent 351 heavy duty enough for a school or hospital entrance?
That is what it is built for. Grade 1 under ANSI/BHMA A156.4, heavy duty rating, forged steel arms and captivated brass valves, specified for high-traffic environments like schools, healthcare facilities and commercial buildings. It is a commercial closer, not a residential one.
11) Can this closer go on an exterior door?
Yes, the 351 is rated for both interior and exterior use with weather-resistant construction and captivated brass valves. On an exterior door expect to dial the spring power up from the factory size 3 setting to overcome wind and stack pressure.
12) Is the LCN 1260-3077 a direct substitute for the Sargent 351 standard arm?
They are not interchangeable. The LCN 1260-3077 is a regular arm supplied with a parallel arm bracket for the LCN 1260 Series closer, so it fits an LCN 1260 body. The Sargent 351-UO TB EN is a complete surface closer with a universal standard arm, and its forged steel arms are interchangeable across the Sargent 351, 1431, and 281 Series. If the existing hardware is an LCN 1260, use the LCN arm; if it is a Sargent 351, 1431, or 281, use the Sargent arm.
13) The door needs a stop built into the arm so it cannot swing into a wall - what should I use instead of the 351 standard arm?
The Sargent 351-UO TB EN universal standard arm does not integrate a stop. When the arm itself has to limit the swing, a dead stop parallel arm is the part to specify - the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly built for the SC60A Series. It mounts parallel arm on the pull side of the frame and stops the door at the set point. The Sargent 351 closer body itself does support parallel mounting, so a parallel arm configuration is an option on that body as well; the dead stop function is what differs.
14) The door has an automatic operator on it - does the Sargent 351 arm work there?
No. The Sargent 351-UO TB EN is a manual surface door closer with a universal standard arm, Grade 1 and UL Listed for fire door use. Arms for power operators are separate parts - the Falcon 8230-3077PLCM is a standard arm with track made for the Falcon 8230 Series automatic door operators. If the opening is powered, order the operator manufacturer's arm; the 351 arm is for the Sargent manual closer body.
15) What finish does the Sargent 351-UO TB EN come in?
Sprayed aluminum enamel (EN), a painted silver-tone finish that reads neutral against most aluminum and hollow metal frames. That is the single finish on this configuration.
16) What do I need on hand to install the Sargent 351 closer?
Work from the Sargent template supplied with the closer to lay out the mounting holes on the door and frame, then drill for the thru bolts. Because this is a TB (thru bolt) configuration, you need access to both faces of the door. After mounting, set the spring power for the door and adjust the closing and latching speeds, then cycle the door through its full swing to confirm it latches.
