Q. Do you install?

Q. Do the doors come with tracking / rails?

A. No we do not supply tracks with the doors but they are available for purchase if you need them. Contact the office to discuss; they will need the full height and width of the area where the tracks will be installed.

Q. How do I know if the tracks I have are correct?

A. See our measuring guide for examples of the tracks that are required for our doors to corrcetly function; there are also examples of the types of tracks that are not suitable for your doors - How to measure a sliding screen door

Q. What are the recommended measuring deductions for Sliding Doors?

A. We can only advise as to the standard allowances; some doors may have individual quirks. If you are measuring an existing screen door the allowances will already have been made so just enter the exact measurements from this door. If you are measuring for a new screen door our Product Builder will guide you through how to measure off the sliding door tracks, and it will make the deductions for you. The measurements you provide will be the exact measurements your door will be fabricated. Please check your tape for accuracy.

Note: Measure your door from the outside looking in. Standard drop/height deduction is 12 mm, this is the amount of adjustment in the rollers. No deduction is required for the width.

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 supplied with all security screen doors and is fitting during installation. Most glass doors will have a receiving interlock located on the fixed glass panel (1.4).

There are three different sized receiving interlocks:

  • 3 mm offset interlock

  • 7 mm offset interlock

  • Flat interlock

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

A. You have two options; either 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. Or purchase a receiving interlock from the list of Addons at Step 3 of the Product builder.

Use the following guide to identify the receiving interlock you require:

  • 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 - 10 mm must be added to the width of the screen door for this interlock selection.
