CoFold is the ultimate in exterior folding systems and opens up a wealth of new design possibilities. The CoFold System has been designed to maximise the flexibility of a room’s living space, removing barriers and enabling the user to have an indoor/outdoor experience by fully opening up exterior walls. The system which operates with effortless ease combines the benefits of folding doors with the ability to keep out the weather with no corrosion worries. This modern, contemporary feature will increase available living space whilst allowing natural light to envelop the room. System Capacity Maximum leaf height - 3300mm Maximum leaf weight - 100kg Maximum leaf width - 1000mm Leaf thickness - 35-68mm* * For thicker or thinner doors please contact Coastal Technical Team For doors between 35-47mm use an alternative flush bolt Applications 􀂚􀀁 Residential and commercial timber exterior folding applications 􀂚􀀁 Specially suited to coastal environments made from 316 stainless steel. 􀂚􀀁 End folding timber doors folding to one or both sides 􀂚􀀁 Standard folding configuration features doors folding outward. Inward folding doors can be used where the doors are not directly exposed to the weather. 􀂚􀀁 Premium security features 􀂚􀀁 Recognised weather resistance The folding unit is not hinged to post, but is pivoted in the track and floor. All door leaves are of equal width. A swing leaf can be included by incorporating an odd number of leaves. For full weather protection, doors, frame and track should incorporate the seals provided in the CoFold range. Cill and frame construction should be in accordance with the CoFold fixing instructions. Intermediate hangers and hinges are non rebated. www.coastal-group.com

Preparing the opening
Preparing the door frame
Ensure the opening is square and all load bearing areas are
suitable for the weight of the system. Take particular care to
ensure there is sufficient strength in the structure above the
opening to take the concentrated weight of the doors, when in
the open stacked position. The CoFold system provides +/3mm of horizontal and vertical adjustment. Use a plumb line to
ensure that the centre line of the track and the centre line of the
channel are offset by 19mm.

Preparing the door leaves
Door leaf width calculation
1. Decide how many door leaves you want in the opening.
2. Add together all the 3mm clearances required between door leaves and the jambs (there will be one more than the number of door
leaves). This is the total clearance figure.
3. Measure the finished opening width (W) and deduct from this the total clearance figure.
4. Divide this new figure (finished opening width minus total clearance) by the number of doors to produce the actual door width. (N.B.
all doors with the Cofold system are the same width).
For example: For a 4 door leaf system with a finished opening width of 2345mm the door leaf width would be 2345mm minus (5x3mm)
divided by 4 (number of door leaves) = 582.5mm.
Door leaf height calculation
Leaf height = finished opening height (see diagram 7) minus 66mm.

INSTALLATION
1. Ensure that you have all the required parts. Unpack the
components and identify the parts. Lay the parts on the
ground in the same configuration as they will be when
installed. It is recommended that a light smear of general
purpose grease is applied to all bolts prior to assembly.
Diagram 18
2. Cut the track to the required length and pre-drill for
fixings in accordance with diagram 18. Please note that the
extra fixings are required where the doors stack together.
TOP PIVOT SECURING BLOCK
3. Cut the channel to the required length and fit in the sill.
Drill drainage holes (see diagram 1).

4. Remove all the wheel assemblies and pivot block from
the hanger and pivot bolts, and disassemble top pivot
block assembly.
PIVOT CAM
5. Slide the wheel assemblies and track pivot block into
the track in the correct order, orientation, and position
and fix the track in position. Reassemble top pivot block
assembly (see diagram 19).

6. Remove the bottom pivot assembly and guide roller
assembly (see diagram 20). Disassemble the bottom pivot
assembly.

7. For installation, assemble leaves in pairs via the hinges.
To improve the ease of installation pre-drill pilot holes for
all hinge parts. Fit kits U1, 7,U4 and U9 (optional) to first
pair of leaves.
Please ensure all 4 screws are fixed per end hinge.
8. Screw the bottom anchor of the bottom pivot assembly
to the base of the channel 11mm from the jamb. Please
note, the screw nearest the end of the bottom anchor is
closest to the jamb (see diagram 21). Reassemble the pivot
assembly leaving the clamping screws loose (see diagram 25).
9. Suspend pairs of leaves by engaging top pivot and
hanger bolts using 5mm Allen key supplied (see top of
diagram 20).
10. Attach the bottom pivot and guide assembly to their
respective hinges, adjust the bottom pivot side plates
position so that it engages with the hinge bolt. Tighten
pivot and guide strap bolts (see diagram 22).
11. Lift the next pair of leaves into position and support
their weight by screwing the hanger strap bolt into the
hanger wheel assembly and fixing the second and third
leaves together.

ADJUSTMENT
Height Adjustment (± 3mm)
1. Close leaves and adjust the door height to achieve an
equal gap between the top of the leaves and the track (a
9mm gap is recommended). (see diagram 23).

2. Once the adjustment is complete use the Allen key to
tighten the locking hanger grub screw until secure.
Lateral Adjustment
1. With the unit still in the closed position, slide the set of
leaves towards the jamb to obtain the desired gap
between the jamb and the pivot door. A gap of 3mm is
recommended using the adjustment cam. Once in
position tighten the clamp screws. (see diagram 25).

SAME METHOD OF
ADJUSTMENT APPLIED

2. Fold the leaves and adjust the bottom side plate using
the Allen key provided so that the gap between the door
and the jamb is the same over the full length of the door.
3. Tighten the two clamping screws to lock the side plate
to the bottom anchor.
4. Once the pivot door is in the correct position insert
and tighten the locking pivot grub screw from the inside
position. (as shown in diagram 24)

CARE AND MAINTENANCE
To provide years of trouble free operation, it is
recommended that the track is kept free from dirt and
debris. Periodically replace the general purpose grease on
all bolts. To prolong the appearance of the exposed hinge
parts, it is recommended they are periodically washed
with soap and water. Maintenance is required on all
components including stainless steel to validate
manufacturers warranty. For further maintenance details
please refer to our website.

U9 Intermediate Pivot Set
1. The CoFold U9 intermediate pivot set shown in Diagram 1, should
be fitted to the pivot door mid way between the U1 top and bottom
pivot assemblies. The U9 hinge must be positioned on the same centre
line as the U1 top and bottom pivot hinge bodies.
5. Screw the frame support plate and the face plate onto the opening frame
preparation, as shown in Diagrams 3 and 5.
2. Rout the door and drill the pilot holes as shown on Diagram 2. Fit the
hinge body using the four screws provided.
7. Fit the U9 cover sleeve on to the U9 hinge body and drop the main
strap bolt into position, as shown in Diagram 6.
3. Using Diagram 3, 4 and 6 locate the position of the threaded link arm
receiving hole on the the opening frame. Starting from the central point of
the threaded link arm receiving hole (as indicated on Diagrams 4 and 5)
mark the location of the two screw holes for the face plate. Using the face
plate as a template mark out the routing detail for the face plate and rout.
8. Screw the threaded link arm fully into the frame support plate. The
centre of the threaded hole in the link arm should be positioned to
receive the strap bolt. Screw the strap bolt in to the link arm until there
is a 2mm gap between the head of the strap bolt and the hinge body, as
shown in Diagram 6.
4. Drill the Ø12mm hole for the threaded link arm receiving hole and rout
the opening frame to mount the Frame Support Plate flush if required
(Diagram 3).
9. Adjust the U9 pivot set to ensure the clearance between the pivot door
and the frame is uniform (Diagram 7).
6. Fit the pivot door into position using the U1 pivot set.
Note: These fitting instructions should be used in conjunction with the CoFold Ultra Fitting Instructions
