What is a Size 2-4 door closer?

A Size 2-4 door closer is an adjustable overhead door closer that supports power sizes 2 to 4. It's suitable for doors up to 1100mm wide and 80kg, typically used on internal doors in commercial environments.

Can Size 2-4 door closers be used on external doors?

Although some people do use them externally, Size 2-4 door closers are not generally recommended for external use due to weather exposure. Manufacturers typically don't guarantee performance in those conditions.

What does Back Check mean on a door closer?

Back Check is a feature that slows the door's opening if it's pushed too hard, helping to prevent damage to walls and the door itself.

Size 2 - 4 Door Closers

Size 2-4 Door Closers for Internal Fire Doors & Commercial Use

Explore our high-quality range of EN 2-4 door closers – designed for internal doors in schools, offices, care homes, and other commercial spaces. With adjustable power settings and CE-marking, these closers ensure controlled, safe door operation in line with UK building regulations.

A Size 2-4 door closer refers to an overhead door closer that can be adjusted to operate at power sizes 2, 3, or 4 depending on the door width and weight. Typically suitable for doors up to 1100mm wide and 80kg in weight, these closers are ideal for internal use where controlled, secure closing is essential—particularly in fire safety situations.

Where Size 2-4 Door Closers Should Be Used

These closers are commonly fitted to internal doors in commercial buildings like schools, hospitals, care facilities, hotels, and modern office spaces. They are particularly useful on fire doors, ensuring compliance with EN 1154 standards. However, they're generally not suitable for external doors, due to exposure to wind and unpredictable conditions. For external use, consider a stronger size such as Size 2-6.

Understanding Fixing Methods: Pull Side vs Push Side

Most door closers are mounted on the pull side of the door (same side as hinges), offering the simplest installation. However, when this isn't feasible, a Figure 66 bracket can be used for a push-side (parallel arm) configuration, especially useful in tighter spaces or where aesthetics matter.

Optional features like Back Check and Delayed Action are also available with some models. Back Check prevents slamming when doors are thrown open, while Delayed Action provides extra time before the door begins to close — ideal for care homes or disabled access areas.
