Authorized service across Brevard County for the 281 Series cast iron Powerglide, 351 Series heavy-duty Powerglide, 1431 Series adjustable, 250 Series, 1250 Powerglide, and the legacy arm interchangeability across the entire Powerglide family.
Parent company: ASSA ABLOY (acquired 1996)
About Sargent
Sargent Manufacturing Company (founded 1864, acquired by ASSA ABLOY in 1996) produces the Powerglide Series of commercial door closers — a Grade 1 lineup specifically positioned for high-security, government, courthouse, correctional, and institutional applications where the closer sees aggressive use and demanding code requirements.
The defining feature across the Sargent Powerglide lineup is arm interchangeability — the heavy-duty forged steel arms are mechanically interchangeable between the 281, 1431, 250, 1250, and 351 Series. One building with mixed Powerglide models can share arm parts across all closers, simplifying inventory for facility managers. Combined with the standard separate brass low-sensitivity control valves (captured to prevent accidental removal, adjustable with 1/8" Allen wrench), the Powerglide platform is designed for long-term institutional serviceability.
Sargent is typically the spec on government buildings, courthouses, correctional facilities, high-security commercial, and any institutional building where ASSA ABLOY hardware is specified alongside Sargent exit devices and locks. For buildings already running Sargent mortise locks or 80 Series exit devices, Sargent Powerglide closers keep the entire hardware package under one parent brand.

Arm Types & Mounting Configurations
Door closer arm choice is the single biggest decision after brand/size — it determines mounting location, how the door behaves when fully open, and whether hold-open or controlled-stop is built in.
| Code | Arm Type | Mount | Function |
|---|---|---|---|
| O / OZ / OZA (25-O) | Regular arm | Pull side | Standard regular arm for Powerglide — projects into room. Cross-compatible across 281, 1431, 250, 1250, 351. |
| UO | Universal arm | Multi-mount | Universal arm configuration compatible with multiple mounting positions. |
| PH9 / 25-H ("UH") | Holder arm | Any mount | Friction hold-open arm — Powerglide family standard. Holds door at adjustable angle via hold-open nut. |
| PH10 | Heavy-duty holder arm | Any mount | Heavier version of the PH9 holder arm for abusive applications. |
| P9 / P10 | Parallel arms | Push side | Parallel arm variants — P9 standard, P10 heavy-duty. Push-side mounting. |
| CPS | Closer Parallel Stop | Parallel | Parallel arm with integrated stop — prevents door over-travel. |
| CPSH | Closer Parallel Stop Hold | Parallel | Integrated stop + hold-open in single arm — Powerglide equivalent of Norton's CLP8000 concept. |
| PSH | Parallel Stop Hold | Parallel | Alternative integrated stop + hold-open arm designation. |
| PSH-TB | Parallel Stop Hold, Through Bolt | Parallel | Through-bolt mounting option — for maximum security on vandal-prone doors where standard screws pull out. |
| Backcheck | Adjustable backcheck | Any | Protects door and hardware from damage during opening cycle. Not a substitute for a door stop. Adjustable with 1/8" Allen wrench. |
| Delayed Action | Optional delayed action | Any | Permits easy access for physically impaired individuals — delays closing from full open. Standard adjustable with 1/8" Allen wrench. |

Common Sargent Repair Scenarios
- Powerglide closer closing too slowly / fast — separate brass control valves regulate door speed, latching, and backcheck independently. Adjust with 1/8" Allen wrench. Valves are captured to prevent accidental removal.
- Hold-open arm (PH9 / 25-H) won't hold — adjust large hex bolt on hold-open assembly. If worn, replacement arm is cross-compatible across 281, 351, 1431, 250, 1250 — one arm part stocks multiple closer models.
- Arm broken or bent — Powerglide arms are interchangeable across the entire 281/351/1431/250/1250 family. If we stock an arm for one Sargent model, it fits all five.
- 281 cast iron closer leaking — internal seal failure. Cylinder replacement typically required. 281 parts availability is good through ASSA ABLOY channels.
- Backcheck too abrupt (damaging closer) — set backcheck valve for slight cushioning only. Never use backcheck as a door stop — always install a physical door stop for over-travel protection.
- Spring size wrong for door — 1431 spring is adjustable 1-6. 281 and 351 also adjustable. Verify door size and weight, then set spring size per Sargent sizing chart.
- CPSH integrated stop-hold arm not engaging — stop angle adjustment or hold-open friction adjustment. Sequential adjustment, both on the arm assembly.
- Powerglide cover missing — replacement covers available in all finish codes. Non-handed, installs with 2 screws per cover.
- NFPA 80 fire-door inspection failure — verify closer closes and latches fully on every cycle. Valve adjustment, spring sizing, or full closer replacement per root cause.
Automation & Access Control Integration
- CPSH / PSH integrated stop + hold — single-arm solution for doors needing both dead-stop at full open AND friction hold. Sargent's equivalent of Norton CLP8000 concept.
- Delayed action option — permits easy access for physically impaired individuals; delays closing from full open for programmed duration.
- ADA compliance — 281 Series specifically designed to meet ADA (5 lbs interior / 8 lbs exterior opening force). Full Powerglide family adjustable to ADA levels.
- Electric hold-open integration — pair Powerglide closers with separate magnetic hold-open devices tied to fire alarm. Standard ASSA ABLOY integration practices apply.
- Access control integration — Sargent closers coordinate with Sargent 80 Series exit devices, Sargent 8200 series mortise locks, and electric strikes. Compatible with PDK.io cloud access control and traditional card systems.
- Auto operator pairing — Powerglide works cleanly with ASSA ABLOY's Besam and Record auto operator families for ADA entry automation.
Fire Rating & Code Compliance
- 281 Series: UL-listed for self-closing fire-rated doors, ANSI/BHMA A156.4 Grade 1.
- 351 Series: UL-listed for fire-rated doors, Grade 1.
- 1431 Series: UL-listed for fire-rated doors, adjustable spring 1-6 covers most fire-rated door sizes.
- ADA compliance: 5 lbs interior / 8 lbs exterior opening force per 281 Series spec sheet.
- NFPA 80 annual fire-door inspection: we service Powerglide for inspection readiness including close-and-latch verification.
- Fire-rated doors: closer must close and latch fully on every cycle. No dogging, no hold-open unless via fire-alarm-tied electric hold-open.
- Sargent patents pending per ASSA ABLOY policy — all current production certifications honored through brand rebrands.

Is Sargent part of Yale or Norton?
All three are ASSA ABLOY brands but they're separate product lines. Sargent was acquired by ASSA ABLOY in 1996 and maintains its own closer line (Powerglide Series), lock line (8200 mortise, 6500 cylindrical), and exit device line (80 Series). Yale and Norton are also ASSA ABLOY but use different product engineering and mounting patterns. Within ASSA ABLOY: Yale arm parts cross with Norton arm parts (same shoe assemblies, hold-open arms, brackets). Sargent Powerglide arms cross internally across 281/351/1431/250/1250 — but NOT with Yale or Norton arms. Sargent is its own ecosystem within ASSA ABLOY.
What's the difference between Sargent 281 and 351?
Both are Grade 1 Powerglide heavy-duty closers. The 281 is the cast iron flagship — maximum durability for the most demanding institutional applications. The 351 is a slightly lighter-duty version positioned for high-traffic commercial where cast iron isn't required but Grade 1 durability is. For new government and correctional specs, 281 is the typical default; for high-traffic office and healthcare, 351 saves some budget with similar long-term performance.
Is the Sargent 1250 related to the LCN 1250?
No — unrelated products, different manufacturers. Sargent 1250 Powerglide is part of the Sargent/ASSA ABLOY Powerglide family with cross-compatible arms across 281/351/1431/250/1250. LCN 1250 is an Allegion product specifically engineered as a drop-in replacement for Norton 1600, Yale 50, Falcon/Dor-O-Matic SC60, LCN 1260, and International 8050. Same numerical designation, different products, different mounting patterns, different parts. When ordering, always specify "Sargent 1250" or "LCN 1250" to avoid confusion.
Can Powerglide arms really interchange across 281, 351, 1431, 250, and 1250?
Yes, for the heavy-duty forged steel arms. Sargent engineered the Powerglide family specifically for arm commonality — one building running a mix of 281, 351, and 1431 closers can share arm parts across all of them. This is a genuine inventory advantage for institutional facility managers with multiple Powerglide generations across a property. Valves and internal components are model-specific; arms are cross-compatible.
What does CPSH mean in a Sargent arm specification?
CPSH = Closer Parallel Stop Hold. A parallel-arm variant that integrates both a dead-stop (prevents door over-travel) AND a friction hold-open (holds door at adjustable angle) in a single arm assembly. Sargent's Powerglide equivalent of Norton's CLP8000 CloserPlus concept — and LCN's HCUSH (hold-open cushion). Used on doors that need both stop and hold-open without installing two separate devices.
Do you service older Sargent closers that predate the 1996 ASSA ABLOY acquisition?
Yes. Pre-ASSA ABLOY Sargent closers use the same Powerglide platform with the same cross-compatible arm design. Parts availability on very old units (pre-1990) may require OEM special orders or salvage parts, but the fundamental engineering hasn't changed — a 1985 Sargent 281 and a 2024 Sargent 281 share arm compatibility. For government and courthouse buildings that have run Sargent Powerglide for decades, we service across generations.
Should I spec Sargent Powerglide for my new commercial project?
Depends on the rest of the hardware package. Sargent makes sense if: (1) you're also specifying Sargent mortise locks (8200 Series) or Sargent exit devices (80 Series), keeping one parent company across the hardware package; (2) the project is government, courthouse, correctional, or high-institutional where Sargent is commonly spec'd; (3) the facility manager already runs Sargent across multiple buildings and wants continuity. If the rest of the hardware is Yale/Norton/Corbin Russwin, those brands may integrate more cleanly at the arm-parts level (Yale and Norton cross-compatible with each other). If you're going Allegion (Schlage/Von Duprin/LCN), stay with LCN for closers.
