Sliding Door Measurement

Steps

 

1. Measure heights

2. Measure widths

3. Measure lock

TRACKING

Our doors have industry standard top and bottom rollers, you must have suitable tracking to accommodate these rollers.

 

                                   TOP SLIDING TRACK OR TOP H TRACK                                           

 

                                 BOTTOM PIP TRACK 

Method

1. Measuring from an existing screen door:

If you have an existing door, and you are happy with the fit then we suggest that you measure this door and use these measurements for your new door.

2. Measuring for a new screen door:

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 (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.

Interlocks

Frame Interlocks are supplied with all SWH 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 door is locked on both sides, see diagram below.

frame interlock (1.3) is fixed to the back of the sliding door at the point of installation so as to have it interlock with the receiving interlock (1.4) which is located on the fixed glass panel.

No Receiving Interlock?

  1. Substitute the frame interlock for a bug seal (1.5) this will eliminate insects coming from the through the gap between the door and fixed panel – indicate this change when placing your order, frame interlock is supplied with all Security Sliding Doors.
  2. Purchase and install a receiving interlock; call 02 8764 4628 for assistance.

Need to install Receiving Interlocks?

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

  • 7 mm
  • 3 mm
  • Flat 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.

 

Door width with a receiving interlock: Measure from the point where the lock striker will be mounted into the receiving channel (1.6) to the outside edge of receiving interlock on the fixed glass panel (1.7).

There are three different sized receiving interlocks:

  • 3 mm offset interlock
  • 7 mm offset interlock
  • Flat interlock

3 mm offset interlock: When measuring for widths with 3 mm offset interlock allow no deductions.

7 mm offset interlock: When measuring for widths with 7 mm offset interlock allow no deductions.

Flat interlock: When measuring for a flat interlock add 10 mm to your initial door width measurement. The reason for this is to have the frame interlock that is to be located on the back of the door to have . The nature of flat interlock does not allow enough room for the frame interlock to go between itself and the fixed glass panel, therefore adding 10 mm will allow the frame interlock to locate behind the fixed glass panel to allow room.

Door width without a receiving interlock: If there is no receiving interlock and you elect to have a bug seal, measure to the back, glass side of the fixed panel.

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).
