About this item
The Accentra 4420 and 4420T are the holder/stop arm configurations from the Yale 4400 Series institutional door closer line. If you searched "yale 4400 door closer", "accentra door closers", "door slow closer", or "yale 4400 closer"- this is the product. Accentra is the current brand name for Yale commercial hardware under ASSA ABLOY. The 4400 Series model numbers, specifications, and arm accessory compatibility carry forward directly from the Yale catalog. Same closer, same valve design, same UL listing- new label.
4420 vs 4420T: The One Difference That Changes the Application
The 4420 and 4420T share the same closer body, the same rack and pinion mechanism, the same size 1-6 spring range, and the same holder/stop arm geometry. The T designation is the only meaningful difference between the two models.
The 4420 is the non-hold-open version. The holder arm stops the door at a set angle and holds it there mechanically through friction in the arm mechanism. The door can be pushed past the stop point with enough force- it's not locked open. When foot traffic or air pressure releases the door, it closes normally.
The 4420T is the hold-open with thumbturn version. The arm includes a thumbturn mechanism that positively locks the door open at the set stop angle. Once the door reaches the open position and the thumbturn engages, the closer spring cannot pull the door closed. The door stays open until someone manually releases the thumbturn. This is the correct specification on openings where the door needs to stay open reliably through traffic, HVAC pressure, or exterior wind without being pushed closed accidentally.
Note: The 4420T is not a fire-rated hold-open device. On fire-rated doors, an electrically operated hold-open system tied to the fire alarm is required. The 4420T is for non-fire-rated openings only.
What "Door Slow Closer" Searches Are Actually Looking For
If you searched "door slow closer"- the closing speed on the 4420 and 4420T is exactly what controls this. The 4400 Series has three separate, independent, staked valves: one for sweep closing speed, one for latch speed, and one for backcheck intensity. Each valve adjusts independently without affecting the others.
The sweep valve controls how fast the door swings through the main arc of its closing travel. The latch valve controls closing speed in the final few degrees before the door contacts the frame- this is the "slow" phase that protects the door from slamming into the frame and latch. The backcheck valve cushions the door on the opening arc to prevent it from slamming against the wall or travel stop.
Staked valves means each valve is permanently staked in the closer body- they can be adjusted in and out to change flow rate but cannot be accidentally removed or back-driven out entirely. This is an important design detail for institutional facilities: a maintenance person or building user cannot inadvertently disassemble the valve while adjusting speed, and the valves won't migrate out of position over years of use.
The 4400 Series Institutional Platform
The 4400 Series is Yale's institutional-grade surface door closer line- the specification used in schools, hospitals, government buildings, and commercial facilities where the closer is expected to survive decades of hard daily use. The 4420 and 4420T exceed 10 million operating cycles in Yale's testing protocol. The body is cast aluminum. Pinion and piston materials are upgraded from the standard commercial grade closers in the Yale line.
The size 1-6 single spring is the key simplification in the 4400 Series. Many door closer lines require separate bodies for low-spring and high-spring ranges. The 4400 uses one body that covers the full range from size 1 (lightest- for light interior doors and ADA accessible door force requirements) through size 6 (heaviest- for large exterior doors with wind resistance). The spring power is adjusted via the power adjustment shaft screw. This means one closer body SKU covers every standard door weight in a facility, simplifying procurement and inventory.
Holder/Stop Arm: Stop Angle Range and Accessories
The holder/stop arm on the 4420 and 4420T dead-stops the door at a predetermined angle between 85 and 110 degrees, adjustable in 5-degree increments. Accessories required for some installation configurations: the 6890 and 6891 accessories are required for narrow frame installations on the 4420. The 2019L accessory is required for flush partition installations on the 4420T. These are sold separately.
Mounting is push side- the closer body mounts on the push face of the door, opposite the hinge side. The 4420 and 4420T are non-handed. The closer body installs on both left-hand and right-hand doors.
