You will need.
Our doors have industry standard top and bottom rollers, you must have suitable tracking to accommodate these rollers.
BOTTOM PIP TRACK TOP SLIDING TRACK OR TOP H TRACK
Seconline Sliding stacker doors come in a couple of different combinations. For this particular application we are referring to two sliding glass panels and one fixed glass panel. Please see details for both width and drop measurements below. If you are not entirely sure then please contact support staff at Seconline.
1. Measure the entire distance between the inside of the receiving channel to the far side of the receiving interlock that is located on the fixed glass panel.
2. Add 70 mm and divide this number 2 to give you your individual door sizes (see animations above).
Note: We add the 70 mm as the doors will overlap in the centre and you will have less visual impairment if the two door frames are in line rather than a total of 140 mm.
1. Measure from the top of the bottom track to the bottom of the top track or the base of the top U channel and deduct 12 mm as per diagrams below. Measure at several points to be assured that there is no great variation. Use the shortest measurement for all.
NOTES: when you are measuring that there is no massive variation in the drop measurements as can occur in some older doors or poorly installed doors. It is important that the gap between the top and the bottom tracks are somewhat parallel generally within a 5 mm margin as a maximum. If this is not the case then tracking may be necessary.
The two Seconline Sliding Security Screen doors will have to be connected so as to open and close using the active door and interlock in the closed position, this is done by using a frame interlock on the back of the active door (the term active door refers to the door that has the lock and the term non-active door will refer to any remaining doors), the non-active door which will have an offset interlock so that the connection is made during the opening and closing process. In most cases you will need a 3 mm offset interlock for this purpose, however not always.
This will enable anyone closing the doors to pull the active door from the lock handle and as it slides into the fully lock position. When the locked position is in place it will mean that the back of the non-active door will be locked into the fixed glass panel on one side and interconnected with the other door in the middle and locked into the closing channel on the locking side.
If there is no interlock attached to the fixed glass panel frame then we will need to identifying precisely which receiving interlock is most suitable to your doors.
1. No Interlock on fixed panel frame
If the distance from the face edge of the fixed glass panel to the centre of the bottom track is greater than 20 mm then a 7 mm offset interlock is required.
If the distance from the face edge of the fixed glass panel to the centre of the bottom track is less than 20 mm and greater than 16 mm then a 3 mm offset interlock is required.
If the distance from the centre of the top and bottom track to the face edge of the fixed glass panel is less than 16 mm then a flat interlock is required - this may cause an issue so please call to discuss.
2. Interlocks to connect the sliding screen doors
Measure the distance from the centre of the first bottom track to the centre of the second bottom track.
LOCKS -THE LOCK SIDE IS DETERMINED FROM THE OUTSIDE LOOKING IN
LOCK ABOVE - Using the guide below measure to the top of the glass door handle and add 120 mm.
LOCK BELOW - Using the guide below measure to the bottom of the glass door handle and deduct 60 mm.
