The Engineer's Choice
Yale's 4400 Series Institutional Door Closers offer customers the ideal combination of superior performance, quality and strength. With upgraded pinion and piston materials, improved valve design, and staked valves, the closers are the most efficient, dependable closers in the industry. The size 1-6 spring also simplifies the process of specifying and ordering product.

This U.L. listed, ANSI/BHMA Grade 1 certified closer has a proven history. It is an ideal choice for interior or exterior doors in facilities that demand reliability such as schools, office buildings, hospitals, department stores and airports.

Features: Aluminum Alloy Housing:

• Closer bodies are constructed of a special aluminum alloy, carefully selected to accommodate interactive steel components and operating conditions

Sweep Speed Control Valve:

• Allows adjustment of door speed from the door's full open position down to approximately 10° from the closed position.

Adjustable Backcheck Cushion Valve:

• Provides control of the door in the opening cycle, beginning at approximately 75° of door opening. It slows/cushions the door opening when the door is forcibly opened beyond its pre-adjusted limits.

Rack & Pinion Operation:

• Provides a smooth constant control of the door through its full opening and closing cycle. 180° door swing can be achieved when door, frame, hardware and arm function do not interfere.

Latch Speed Control Valve:

• Allows adjustment of door speed from approximately 10° down to the door's fully closed position.

Adjustable Backcheck Position Valve:

• Allows the door opening position, where backcheck cushioning begins to be adjusted to a greater door angle up to a maximum of 20º farther (approximately 95º).

Non-handed:

• With few exceptions all 4400 series door closers are non-handed and can be installed on either right or left-hand swing doors. Pinion shaft extends vertically through the closer body in both directions. Some options, as noted on page 5, will require that the hand of the closer be specified.

Closer Fluid:

• All door closers are supplied with a temperature stable, multi-viscosity fluid. This fluid will permit the door closer to perform within a wide temperature range: from very high to as low as -40°F.

Standard Molded Covers:

• Molded of high-impact U.L. listed material. This cover is non-handed for all applications. See page 5 for optional metal cover.

Tri-Packed:

• 4400 series come with screws, brackets and soffit plates to allow for regular, top jamb, and parallel arm installations.

Warranty:

• Limited 25-year warranty for defects and life of the building on the aluminum housing.
