How To Install Cobra Seal

SAFETY:
Safety glasses and ear protection to be worn.

WARNING
It is vital for the safety of persons to follow all instructions.

Any adjustments to the following on either Roller and Sectional Overhead garage doors, MUST be attended to by a quaified garage door specialist:

• auto opener
• spring tension
• repositioning of the HORIZONTAL sectional overhead garage door tracks
• lifting cables

Failure to follow this advice may result in severe damage to the garage door as well as personal injury or death during and after the CLEVERSEAL product installation.

During the installation procedure ENSURE children and any other person/s not directly involved with the installation procedure, are kept clear of the work area and well away from the garage door opening area.

Failure to comply with the installation instructions and the safety warnings may result in serious personal injury and/or property and garage door damage. Please save these instructions for future reference.

Disengage auto openers and DO NOT reengage until ALL seals are installed and the travel of the garage door has been manually tested without the garage door binding. FAILURE TO FOLLOW THIS INSTRUCTION COULD RESULT IN SERIOUS DAMAGE TO THE DOOR, requiring expensive component replacement. Ensure that the remote control device or hand-set is in a safe, secure location, out of reach from children and any other person or persons not directly involved with the seal installation procedure.

NOTE
ONLY AFTER the seal has been fitted and the garage door has been manually operated without binding, RE-ENGAGE the auto opener then, HOLDING the manual release cord in one hand and with the remote control in the other hand operate the garage door, following the garage door as it moves with holding the manual release cord. If the garage door binds or hesitates IMMEDIATELY disengage the auto opener, then make the necessary adjustments until the garage door functions without binding and hesitation in auto opener mode. FAILURE TO FOLLOW THIS INSTRUCTION COULD RESULT IN SERIOUS DAMAGE TO THE DOOR, requiring expensive component replacement

Measure the width of the door (curtain panel) less 0.5mm each side for exact measurement for Cobra installation. Cut to required length.

Remove old strip using a sharp Stanley knife.

If the seals must be cut, mark the length then PULL the brush and santoprene back, away from where the aluminium is to be cut. Cut the aluminium to
length. Slide the brush and santoprene back and cut to the same length as the aluminium using PLIERS or SIDE CUTTERS ONLY.

Cutting the brush with any type of snips, shears or saws will result in the filament dislodging out of the metal backing spline. Using pliers or side cutters to cut, creates a crimp cut, effectively sealing the metal backing spline. As an extra precaution you may prefer to crimp the carrier at each end.

Once installed the Cobra profile will add 5mm to the face of the door. For sectional and roller doors that additional 5mm may foul on the frame as the door negotiates the curve as the door opens and closes.

With sectional overhead & roller garage doors therefore, it is necessary to notch the face of the Cobra extrusion to the outside of the door frame.

Mark the required amount of overlap to be removed and cut through to the top of the curve only (see arrow). Use a battery powered jigsaw, hacksaw or
similar, as options.

Cut back the rubber strip at a 45 degree angle so that the T slot end of the rubber is set back 20mm from the under channel.

We do not recommended the use of grinders due to the excessive force required to cut through aluminium and rough result of grinder cutting.

With both cuts made the result should be as shown.

Fine file to finish.

Begin affixing Cobra to the bottom rail; hold to door & fit into place.

Attach the fixings with screwdriver at 300mm intervals along the length of the door

Repeat process at opposite end for doors over 2.5 meters

Please note that when joining two Cobra Carriers together ensure the brush and santoprene run continuous through the join.

Cobra affixed to bottom of door.

Inserting the rubber strip.

Bottom engaged into groove first and with a pointy object like a nail, guide it into the top groove.

Installed Cobra

Test the garage door manually and make any necessary track adjustments.

Reconnect the auto opener and follow the instructions as per step 1 NOTE. Do not in any circumstances touch the motor of the opener.

You may need to tighten bolts to adjust the garage door track to fit tightly against the Cobra seal. This should be a simple process of tightening the bolts
until the door is completely touching the bottom of door seal when closed.

However, if you have other problems that require adjusting, this should ONLY be performed by a qualified garage door service specialist.

MAINTENANCE
We recommend to regularly run a wood pencil along the full length of the seal when the garage door is open, to remove any collected particles of dust, plant debris or grit. 

NOTE
All garage doors require regular service. Adjustment to the tension springs or lifting cables should ONLY be attended to by a qualified garage door specialist. SERIOUS INJURY OR DEATH can result in unqualified persons attempting adjustments with those components. It is recommended that the garage door be regularly serviced by a qualified specialist although the garage door should also be regularly checked by the owner, especially the lifting cables to observe any fraying of the wire strands, the owner should apply applications of aerosol silicon lubricant (not oil, grease, CRC or other penetrating, moisture disbursement type applications. Silicon or aerosol Tyre Shine products only) to all roller wheels, tracks, auto opener track, once every three months. This maintenance cycle will improve the garage door function, extend the auto opener life and enable the owner to identify any issues that require a qualified specialist to attend.
