Other Frequently Asked Questions


Q. What are the recommended measuring deductions for Sliding Doors?
A. We can only advise the standard allowances. Some doors may have individual quirks. Please provide measurements in millimetres. The measurements you provide will be the exact measurements your door will be fabricated. Please check your tape for accuracy. Measure your door from the outside looking in.

Standard drop deductions – 12 mm.

Standard width deduction: Take no deductions

Q. What are interlocks?
A. 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. 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.

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 10mm 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.

Q. What if my door does not have a receiving interlock.

Substitute the frame interlock for a bug seal 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.

Alternatively a Receiving Interlocks can be purchased from SCREENWAREHOUSE; contact the office for assistance 02 8764 4628.

A. To manufacture your door with the handle compatible with your existing handle for both sliding and hinged doors.
