FINGER-EJECTING GUARD (ALUMINI)

Perfect for existing hinged doors, our surface-mounted finger guard that offers a maximum opening angle of 180° and has a patented finger-ejection system to keep wandering fingers safe.

The unique design sees the semi-circular aluminium body floating on two retracting fabric sections. When the door opens, it moves into the gap and the tear-resistant fabric covers any remaining gaps — as well as ejecting any fingers that may stray inside.  

It’s this clever semi-circular geometry – rather than fabric tension – that keeps fingers safe and uses extremely low force springs to maintain the door’s original opening force.  Its tough aluminium build can also withstand knocks and bumps and wipes clean easily.

 

   

Patented ejection system

As the door opens, the aluminium body floats into the gap and the taut fabric covers any other gaps.  The fabric’s patented finger ejection system makes it almost impossible to trap a finger

Unlike roller blind finger guards, which use fabric tension to keep fingers out, Alumini’s fabric has nominal impact on the opening resistance.  So your doors will still comply with Approved Document M and BS 8300.

Wide opening angle and clear opening width

Alumini’s clever design allows unrestricted door opening up to 180°, making it ideal for gym hall doors where you can’t use floor mounted stops.  

The aluminium profile floats into the hinge reveal gap when the door is open at 100° so it doesn’t block the doorway.  This allows a maximum clear opening width that’s ideal for wheelchairs and trolleys

Budget friendly

We know that budgets are often tight.  But with ALUmini, you can still enjoy a safe and durable solution.  And because it’s hard wearing it can save over £300 compared to plastic finger guards.

Durable

Unlike traditional rubber and roller blind finger guards, Alumini’s polyurethane-backed fabric is easy to clean and tear-resistant, reducing the risk of vandalism.

The hard-wearing aluminium profile is also designed to withstand any knocks in a high traffic environment.

How it works

HOW IT WORKS

Rather than fabric tension, this retrofit finger guard uses semi-circular geometry to eject wandering fingers. The durable aluminium body floats into the hinge reveal gap, with tear-resistant fabric covering any remaining gaps.

As the door closes, the fabric retracts – ejecting any fingers.

Case study: Worcesters Primary School

 

WORCESTERS PRIMARY SCHOOL CASE STUDY

We initially supplied 20 integral finger guards to this school in 2014, as part of an extension built offsite by Portakabin.  They were so happy with the quality and sleek aluminium finish that, the following year, they ordered 80 retrofit surface-mounted finger guards for the existing building, to replace ineffectual and costly plastic guards. Together, our integral and retrofit finger guards now complement each perfectly, linking the existing building with the new extension and ensuring a continuous aluminium finish throughout.

LIMITATIONS OF CURRENT FINGER GUARDS

Plastic

Plastic

As the first attempt at finger safety, plastic guards covered the gap between the door and frame. In some situations, like the home, they’re safe and do the job. However, in high traffic areas, like schools, hospitals, restaurants and retail environments, they’re simply not durable enough.
 

They crack and split
Although cheap, plastic finger guards aren’t built to last. Typically, after between six months and two years of normal use in schools, GPs, restaurants or swimming pools, they split and need replacing.  And once broken, the original danger is exposed, putting fingers at risk.

A maintenance liability
The real cost of a plastic finger guard is anything but cheap. Taken over the typical 25-year lifespan of a school, replacing them costs between £500 and £1,000 per door, making them the most expensive option.

Look cheap
Plastic guards can be unsightly and rarely blend in with the environment. If the interior finish and doors have been carefully planned – perhaps in colourful laminate or attractive veneer – the finger guard should be just as aesthetically pleasing.

 

Rubber

Rubber

Flexible rubber hinge covers were developed to address the durability issues of plastic finger guards.  Hard wearing and tough, they cover the complete gap, however fingers can still become trapped.

Doesn’t solve the problem
Rubber guards merely cover the gap between the door and frame. The rubber cover is rarely taut enough to prevent the guard being pushed into the hinge gap. This leaves open the possibility of fingers wandering into the gap and being trapped in a closing door.

Highly visible
Concertina-like rubber hinge covers are made from a material not usually used on doors. Even in the closed position, customers comment they’re eyecatching and impact the overall aesthetic. 

Gathers dust and grime
The soft rubber surface attracts dust and is hard to clean. The folds also gather grime, which can become a hiding place for bacteria.

 

Roller Blind

Roller Blind 

The single roller blind uses fabric tension to resist fingers pushing into the gap.  And when you consider the cost of hinges, the roller blind finger guard, and the fitting, the cost is similar to our integral finger guard – which designs out the problem, offering superior safety and aesthetics.

Just hides gap
Unlike our clever designs, roller blind finger guards use fabric tension to create resistance and prevent trapped fingers. This is mostly effective but it’s not foolproof. 

Affects opening force
The fabric tension resistance can make it challenging to comply with Approved Document M and BS 8300 (Opening Force for a Door). 

A costly compromise
Roller blinds cost around the same as our Alumax integral finger guard — yet compromise on aesthetics. And if cost is an issue, our retrofit finger guard makes the perfect alternative. It’s durable and doesn’t  impact the opening force.

 

Architectural considerations

ARCHITECTURAL CONSIDERATIONS

 

Installation on door

Alumini is suitable for new or existing timber doors.  These need to have standard butt hinges and a minimum of 90mm on the door face that the profile sits on.  This is measured in the closed position from the stop.  

180° opening angle

Alumini is practical and flexible thanks to its wide opening angle.  So even if Alumax is used elsewhere throughout a school, Alumini is perfect for the gym hall if the doors need to open right out.

Standard length

To keep things simple, Alumini comes in a standard 1925mm length.  It’s also prepared for 44mm doors as standard, so if you have 54mm doors you simply need some additional Size 2 spacers.

Acoustics, door closers and fire rating

As a surface-mounted product, it doesn’t alter the door’s performance at all — so the standard acoustics, door closers and fire rating still apply.

Maximum clear opening width

When the door is open at 100°, the aluminium body moves into the gap between the door and frame. This means it doesn’t obstruct your clear opening, offering easy access for wheelchairs.
