Receiving H Channel
The H-Receiver houses the lock plate, the active door locks into this channel.
Our doors have industry standard top and bottom rollers, you must have suitable tracking to accommodate these rollers.
Tracks are available to purchase from Seconline; please contact the Help Desk 1300 735 405 or firstname.lastname@example.org for a quote or further advice.
BOTTOM PIP TRACK TOP SLIDING TRACK OR TOP H TRACK
Measure the overall width of the opening from the back of the receiving interlock on the left door to the the back of the receiving interlock on the right and divide by two, this will give you the width measurement for each door.
Measure heights at three to five points along the track; take this measurement from the top of the bottom track, to the bottom of the top track (1.1 & 1.2), deduct 12 mm from the shortest length and record this measurement.
If a variation of more than 4 mm exists this may result in the door not sliding properly, and additional tracking may have to be installed to make tracks parallel; contact the Help Desk 1300 735 405.
Frame Interlocks are supplied with all Seconline Sliding Security Screen Doors; 7mm Diamond doors are not security doors and are supplied with a side bug seal.
The purpose of interlocks is to lock the back of the sliding door into the fixed panel simultaneously as the door is closed into the locking position, this ensures that the doors are locked on both sides.
A frame interlock is fixed to the back of the sliding door at the point of installation so as to have it interlock with the receiving interlock which is located on the fixed glass panel (1.3 & 1.4).
No Receiving Interlocks?
If you do not have a receiving interlocks on the fixed glass panel then for the purpose of centre opening sliding doors it is necessary for you to install these.
There are three different size receiving interlock:
Identifying precisely which receiving interlock is most suitable to your doors can be using the following methods:
If the distance from the centre of the top and bottom track to the face edge of the fixed glass panel is greater than 20 mm then a 7 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 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.
When measuring the widths for centre opening sliding doors that do not have receiving interlocks and will need to have a receiving interlocks fitted then the following procedure for measuring needs to be adhered to.
For 3 mm and 7 mm offset receiving interlocks measure from the back of the fixed glass panel on the right-hand side to the back of the fixed glass panel on the left-hand side, deduct 6 mm and divide this measurement by two for the individual door sizes to be ordered.
For flat interlock measure from the back of the fixed glass panel on the right-hand side to the back of the fixed glass panel on the left-hand side. Add 10 mm to this measurement and divide by two for the individual door sizes to be ordered. No deductions will be necessary.
From the outside looking in with the doors in the closed position establish which will be the Active Door (these should mirror your glass doors).
Take your lock measurement from the top of the bottom track, to the centre of where you want your lock handle. This will also be the centre of middle lock striker.
This measurement needs to be a minimum of 125 mm above the top of your existing solid door lock (1.8) or 60 mm below the bottom of your existing door lock handle (1.9).
THE LOCK SIDE IS DETERMINED FROM THE OUTSIDE LOOKING IN
