INTEGRAL FINGER GUARD (ALUMAX)

Perfect for new builds and major refurbishments, our discreet integral finger guard offers complete safety and unrivalled durability. 

Our integral finger guard – Alumax –  designs out the problem of trapped fingers by using a rounded heel to eliminate the gap between door and frame.  As the door opens and shuts, this gap remains constant at just 2mm – too small for fingers to get in harm’s way.

Once fitted, it will last the lifetime of the door, removing the need for regular replacements and saving between £500 and £1,000 per door over 25 years compared to plastic.

 

Lasts the lifetime of the door

Once installed, Alumax will last the lifetime of the door, removing the need for replacements. This can save £500-£1,000 over the door’s life, compared to plastic finger guards.

Designs out the problem

Our integral finger guard reduces the risk of trapped fingers by removing the dangerous gap between door and frame. The clever design means there’s less opportunity for wandering fingers to become trapped. It’s the perfect example of prevention being the best way to protect against accidents.

Blends in seamlessly

Available in a range of finishes, including timber finish and RAL colour, it’s almost invisible to the eye and fits seamlessly into any environment.

Onsite adjustability

The pivot hinge allows onsite adjustment to speed up installation.

This adjustability is both vertical and lateral, so you can set both desired floor clearance and fine-tune the finger-safe gap.

Hygienic 

We chose aluminium because it’s easy to clean.  So it’s perfect for keeping restaurant toilets safe and hygienic

Modular design

In healthcare environments, doors are often subject to extreme damage by trolleys.  Alumax’s aluminium profile can be replaced in minutes.

 

 

CWIM IFOR PRIMARY SCHOOL 

Link many LEAs, Caerphilly County had previously used plastic finger guards but gre frustrtaed with the lack of durability and need for frequent replacements.  This is where we came in.  

We explained how the robust design of our integral finger guard lasted the lifetime of the door, reducing replacement costs, while designing out the problem of trapped fingers.  Naturally this was music to their ears – one simple solution to many issues. 

How it works


 

HOW IT WORKS


The concentric curved profile and pivot point of our integral finger guard means the frame sits almost at a tangent to the door. This allows it to open and close without the edge moving relative to the frame – creating a constant 2mm finger-safe gap.

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

DOOR CLOSER OPTIONS

Whether single or double-swing, Alumax works with wide a range of door closers.

Overhead scissor-arm closer

Our integral finger guard works perfectly with most scissor-arm closers.  However, to ensure they don’t clash, check where the screw fixings are placed on the door frame.  See our technical manual for more details.

Overhead cam action closer 

Cam action closers’ efficiency helps achieve Approved Document M/BS 8300.  Plus, there are no protruding parts when the door is closed.

The closer can also be fitted with a cushion limiter stay.  This small rubber buffer fits into the guide rail, restricting the door’s opening angle in the absence of floor-mounted stops.

Concealed transom closer (Sureclose)

Our overhead concealed door closer is the perfect solution for double-swing 54mm doors.  The closer is fitted in the frame head, eliminating the need for costly floor spring excavations.  Plus, it’s tough, safe and easy to install, as well as having a back check internal brake to prevent damage from misuse.  With the EMAG hold-open option, it can be linked to the fire alarm to ensure fire compartmentalisation.

Floor springs

We’re pleased to supply a special kit with a bottom strap compatible for floor springs. Floor springs themselves are available from a number of manufacturers. Please check compatibility in our technical manual before specification.
 

 

 

ARCHITECTURAL CONSIDERATIONS

 

Opening angle restriction

Our integral finger guard has a maximum opening angle of 110°.  However, we strongly recommend that you restrict this to 100° to prevent the door binding against the door frame.  Floor or wall mounted door stops can be used in most cases.  To avoid issues with underfloor heating, or to prevent the stop becoming a trip hazard, overhead door restrictors or cushion limiter stays fitted into a slide arm door closer can also be used.

Acoustics

Alumax can achieve acoustic rating up to 32dB on 44mm and 38dB on 54mm doors.  Standard smoke seals can be used around the perimeter.  At the threshold, the options are a mechanical drop seal, surface mounted, or a concealed fixed seal, with a raised threshold. See technical manual for details.

L-bracket or floor plate

Both options are available, although we recommend L-brackets.  Fixed into the frame and floor, they help spread the load of the door, helpful if you’re working with a floating screed construction.  It also ensures the bottom pivot point is placed correctly relative to the door frame.
