Two Measure Options are available:

Option 1: Measure your existing screen doors

Measuring from an existing screen doors: If you have an existing doors, and you are happy with the fit then we suggest that you measure these doors and use these measurements for your new doors.

Active Side: Stand outside with your doors closed; identify which door will have the lock, left or right, this is the active door.

Door Widths: Measure the top, middle and bottom widths of each screen door; send us the largest of the three measurements.

Door Height: Measure from top to bottom of each screen door on both the left and right hand sides; send us the shortest of the two measurements for each door.

Lock Height: You can use the existing lock height if desired; first make sure that the new handle will not interfere with the existing glass door handle, do this by referring to the Lock Above & Lock Below instructions at the bottom of the page. Then measure from the bottom of the existing screen door up to the centre of the existing striker, this will be the centre of the new striker and screen door handle.

Option 2: Measure from the tracks for new doors

Active Side: Stand outside with your doors closed; identify which door will have the lock, left or right, this is the active door.

Door Widths (with receiving interlocks) : Measure the entire opening from the outside edge of receiving interlock on the fixed glass panel (1.2) on the right hand side to the outside edge of the receiving interlock on left hand side fixed panel. Deduction 6mm and divide by two to ascretain the individual door width.

Door Width (without a receiving interlock): If there is no receiving interlock you must install them, otherwise there will be nothing to stop the screen doors sliding all the way across and over the fixed panels. See the instructions below "No Receiving Interlock?" for directions on how to measure for receiving interlocks; they can be purchased from the Addons at Step 3 of the Product Builder.

1.21.2

Door Height: Measure lengths at three to four points along the track; take this measurement from the top of the bottom track, to the bottom of the top track, deduct 12 mm from the shortest length and record this measurement. Your track will either have a raised rail (1.3) or it will be a flat U-shaped section (1.4).

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.

Frame Interlocks

Frame Interlocks are supplied with all Seconline double sliding screen doors; the purpose of interlocks is to lock the back of the sliding door into the fixed panel simultaneously as the doors are locked togther in the centre, this ensures that the door is locked on both sides.

A frame interlock (1.5) is fixed to the back of the sliding door at the point of installation, when the door is moved into the locked position this frame interlock will connect/interlock with the receiving interlock (1.6) which is located on the fixed glass panel.

No Receiving Interlock?

You need to purchase and install a receiving interlocks for double sliding screen doors. Using the guide below ascertain what size receiving interlock you will require to suit your tracking then select this interlock as an Addon at Step 3 of the Product Builder.

Measuring for a Receiving Interlock

If your doors do not have a receiving interlocks on the fixed glass panels and it is necessary for you to install them there are three different sized receiving interlocks:

  • 7 mm

  • 3 mm

  • Flat interlock

InterlocksInterlocks

Identifying precisely which receiving interlock is most suitable to your doors can be done using the following methods:

  • If the distance from the centre of the bottom track to the face edge of the fixed glass panel frame (1.7) is greater than 20 mm then a 7 mm offset interlock is required.

  • If the distance from the centre of the bottom track to the face edge of the fixed glass panel frame (1.7) 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 bottom track to the face edge of the fixed glass panel frame (1.7) is less than 16 mm then a flat interlock is required; if you find that you require a flat interlock you must add 10 mm to the width of each screen door.

1.71.7

Lock Height: 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 120 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).
