Pedestrian & Light Vehicular Access Doors

This MK5 range is the perfect answer for all your pedestrian and light vehicle doorways, manufactured to requirements from unique cost efficient modular componentry.

Easy Door Selection

SWINGFLEX MK5 doors are suitable for opening up to 2500mm high and 1800mm wide for double door arrangements. With the inclusion of reinforcing gussets, doors can be increased in size to 3000mm high x 2200mm wide.

Effective Environment Barrier

Because of the standard twin blade brush seals to the back edge of the door frame, the SWINGFLEX MK5 is one of the most efficient doors available against draughts, wind, noise, heat, cold, dust, fumes and insects.
Using special grade PVC, doors can be used as ante doors in freezer application.

This model is ideal for:

Liquor Stores; Cool Rooms
Kitchens; Meat Establishments
Proving Rooms
Clean Rooms
Warehouses; Gymnasiums
Factory Stores


The MK6 Selection is the most flexible solution to a heavy duty impact door for openings used by motorised Forklifts. Manufactured to your specific requirements from cost effective modular componentry.

Door Selection

SWINGFLEX Door Model MK6 is a heavy duty unit designed for motorised traffic. The recommended size range from 2400 to 3600mm in height and 2000 to 3000mm in width. Higher opening can be accommodated by adopting a flexible transome flap above.

Drive Through Safety

The MK6 SWINGFLEX door handles motorised Forklifts safely.
With the see through panels, drivers can foresee any danger right from their driving position. The PVC panel flexes on impact from the Forklift or pallet load, the door opens, and the vehicle passes effectively though the opening.

Features of your Swingflex Door:

See through panels means safe two way traffic flow;
Hands free operation, door opens with a gentle push and closes automatically behind you;
Silent operation by flexible PVC panels absorbing any impact during opening and closing;
Concealed spring controls, fully adjustable to suit your requirements;
Doors are manufactured to clinical requirement as standard;
Hold open controls are available if required;
All PVC used is non toxic and contains no heavy base metals such as cadmium, lead or barium.


Door Model
Mk5 vs. Mk6
For a clear opening upto 2200mm wide (where height is approximately upto 2400mm),Swingflex Mk5 doors are generally suitable (depending on application, type and frequency of traffic).

For openings wider than 2200mm, heavy duty Swingflex Mk6 doors are more suitable. Special brackets and springs are supplied to make Swingflex Mk7D and Swingflex Mk6D doors service openings upto 4000mm wide.
Number of Leaves
Single vs. Pair
Single doors are good for pedestrian traffic. They also work out to be a cheaper option as compared to a Pair for the same size.

Pair of doors are the way to go, if the traffic is Trolley, Pallets, Forklifts or Meat Rails etc. Pair of doors also reduce the possibility of gaps (as the two panels overlap by 100mm in the middle).
PVC Thickness
5mm vs. 7mm/10mm
5mm thick PVC is suitable for pedestrian and low frequency traffic areas.

For a small extra cost, 7mm thick PVC provides a longer life and is recommended for heavy trolley/pallet/fork life traffic areas.

10mm thick PVC gives even longer life and good resistance to air pressure - this is a better option for large openings which have frequent forklift traffic going through.
PVC Finish
Clear vs. Translucent*
Clear PVC is better in areas where there are no customers or which need high visibility.

For customer areas or for private areas, PVC can be made (fully or partly)
Translucent/Satin. This allows the light though, however the milky finish does not allow people to see though.
Brush vs. PVC*
Only Swingflex Mk5 Doors have the provision of seals.

Brush seals are used in dry areas.
PVC seals are used in wet areas.

Swingflex Mk6 doors can also be sealed using PVC strips.
PVC Grade
NT vs. LT*
LT (Low Temp) PVC is used in freezer applications.

For all other applications, NT (Normal Temp) PVC is used.
Bottom Fix
Floor vs. Side*
Bottom Floor Fix provides better support for the door weight - and therefore is usually recommended (except in some situations, like the ones mentioned below).

If the jamb is strong enough, Bottom Side Fix is recommended in wet areas (especially where floor is hosed down with chemical cleaners) this makes it easier to clean the floor and increases the life of the bottom fixings. Bottom side fix is also good for pallet traffic or if the floor is not strong enough (e.g., it has a drain).
Safety Buffers*
0.5mm to 5mm thick
Buffers can be welded to the main panel (on both sides) for protecting the main panel or for safety reasons. These can be in clear or in any colour (subject to availability) to suit your interiors;
Stile and Head Section Both the Swingflex Mk5 and Mk6 doors are made of clear anodised aluminium stiles and head sections with an anti-tear lip (Mk5 also comes with a provision for brush/PVC seals).

Stile section of Mk6 is similar to Mk5 (however, without provision for seals) the Head section is made of plated steel (with anti-tear lip).

The aluminium stile & head can be POWDERCOATED to any available colour;
Spring Mechanism
Single vs. Dual*
Both the Swingflex Mk5 and Mk6 doors come with a fully adjustable spring unit, concealed inside the door stile. This spring mechanism is NOT hold open type (i.e., if opened fully, will not hold the door open, which means that the door will close automatically) - this is calledSINGLE SPRING OPERATION.

Swingflex Mk6 doors can also be supplied with an additional bottom spring. This provides extra torque to the door and assists the head spring in the door operation. This is done for large openings where the spring has to move heavy PVC or when springs have to work against air pressure or wind - this is called DUAL SPRING OPERATION.
Hold Open System*
Latch Type vs Magnetic
Latch Type Hold Open System provides a cost effective way to hold the doors open. This is mounted on the door itself.

Magnetic Hold Open System provides a much stronger, durable and yet easy to use alternative to the Latch Type Hold Open System. This is mounted on the jamb.
Stitch Locking* Stitch locking is also available. This helps in internal security only as it does not allows the doors to open, if locked. This does not come with a pad lock.


We do not supply the jamb.

The jamb requirement depends on how the door is to be fixed into the opening. The fixing points need either of the following for a reasonably strong fixing:

Concrete (or concrete filled blockwork);
Timber - minimum 25mm thick;
Metal Section (Steel/Aluminium) - minimum 5mm thick or
Metal Folded Jamb (Steel/Aluminium) - 1.7mm thick - with torque plates.

For these doors, there are TWO fixing points:

TOP - which can be Top Head Fix or Top Side Fix;
BOTTOM - which can be Bottom Floor Fix or Bottom Side Fix.

For Side Fix (top or bottom), the jamb/frame must have strong/reinforced sides.
For Head and Floor fix, strong head and floor supports are required.

Weight of Doors

This is the door weight ONLY - it does NOT include the weight of packing.

For 7mm thick PVC:: (8.2 x Height x Width) + (6 x Height) + (3 x Width) + 12*
For 5mm thick PVC:: (6.5 x Height x Width) + (6 x Height) + (3 x Width) + 12*

* This value ("12") is for a PAIR of doors, for a SINGLE door this value should be "6"
