The 2840 concealed door closer with a cam and roller mechanism makes it perfect for compliance with Approved Document M and BS 8300 recommendations. It’s fully concealed when the door is closed.
This very slim, un-handed, EN3 tested product is suitable for a variety of metal and timber doors, and features in locations where accessibility and aesthetics are crucial, such as hospitals, care homes, schools and high-end hospitality and leisure projects.
Some of the benefits of choosing a 2840 Concealed Door Closer
• Greater proportion of wood left in the door (unique to this model)
• Ease and speed of fitting
• Fire tested for multiple applications
• Latched or unlatched
• Fire and smoke doors
• No shadowing through from the cut out
Just a few of the Concealed Cam Action’s unique advantages…
Can be used on 44mm FD30 Doors without “shadowing”!
The 2840 is one of the slimmest concealed closers with its 32mm wide mechanism after Intumescent kit is fitted.
Some concealed Cam Actions finish up 36mm wide after being wrapped in intumescent– a whole 4mm extra to chop out of the door!
This means that 2840 intumescent fitted Concealed Cam Action Closer can be used on 44mm doors without “Ghosting” appearing in the timber face. This can reduce the overall cost of a project.
Fire & Smoke tested without extra Smoke Fins on connector bar
Some concealed slide arm closers have passed the smoke test by using plastic fins attached to the connector bar.
The 2840 passed the smoke test without any additional assistance. It is designed with zero tolerance and the intumescent acts as the smoke seal.
This means that the polished chrome, brass or satin stainless connector bar isn’t spoilt by extra smoke fins and still coordinates visually with the finish of the handles and other door furniture.
The visual appearance is critical for Interior Designers with their high-profile projects.
The nature of the Cam has been known to create floppy un-positive latch with some makes of Cam Actions closers.
This soft latch can be a problem when affected by only small amounts of air movement, through-drafts or air conditioning.
The firm latch of the 2840 is difficult to achieve and we’re delighted to say we’ve mastered this!
This means you can have the confidence when specifying concealed cam actions that you will achieve a safe, firm latch which is critical with fire doors.
Sturdy durable valves
This model doesn’t have tiny Allen Key type brass valve adjustment.
This decision was made because the brass can be easily rounded off when adjusting which, when this happens renders the Door Closer inoperable and therefore involves expensive replacement.
The 2840 cam action valve controls are sturdy, and operated with screwdriver giving many years of usage and therefore value for money.
