Other Frequently Asked Questions

Q. What is a Triple Lock Upgrade?

A.  A Triple Lock Upgrade is a locking system that is activated from the locking handle position and has 2 additional strikers. Diagram below

Q. Do Seconline make deductions for hinged doors?

A.  No. The measurements you provide will be the exact size fabricated.

Q. What deductions do I make?

A. We can only advise as to 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.

  • Standard width deductions: 9 millimetres off the widths for three point locks and 8 millimetres off for single locks.
  • Standard drop deduction: 8 millimetres off the shortest length. We keep both lengths the same to ensure door can be made square; a small gap may appear at the bottom of the door. This can be eliminated by installing a bug seal which can be purchased from our accessories section.
  • Take your lock measurement from the bottom [ground] 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 millimetres above your existing door lock or 60 millimetres below.    

Q. What if I have an existing door and it is a perfect fit?

A.  If you are happy with size of the door you have, this is a good idea.

Q. Why do I measure from outside looking in?

A. To determine which side for both lock and hinges.

Q. Can you offer any suggestions to help gain accuracy with measurements?

A. Yes. Measure multiple times and perhaps have someone else measure as well. Remember we will supply the door to the exact measurements you provide.

Q. What if my door is out of square?

A. We can only supply the door with square diagonals. You must provide a top and bottom width measurements. The hinge side will remain straight.

Q. Does the door come with a door closer and bug seal?

A.  No, they can be purchased as an add on or from our Extras page

Q. Do you install?

A.  No we supply only. Installation is not difficult; however we recommend you use a licensed installer.

Q. Does the door come with a door jamb?

A.  No.

Q. Does the door come with screws to fit?

A. Yes for timber fit only - Hinged doors only.

Q. Why do you need a centre of the door handle height?

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

Q. Is the centre of the handle the centre of the main tongue?

A. Yes.

Q. Can I match an existing tongue hole?

A. Yes. If you have an existing tongue hole and it has not interfered with the main solid door handle, then this can be re used. Measure from the bottom up to the centre of the hole and deduct 4 mm.

Q. How far above or below our existing solid door handle do we put our required handle height?

A. Below: Measure from the ground to the bottom of the existing solid door handle and deduct 65 mm. This allows the minimum distance required.

   Above: Measure from the ground to the top of the existing solid door handle and add 125 mm. This allows the minimum distance required.    

Q. Does the internal snib lock the three point lock?

A. Yes.

Q. Do I need to recess the hinges?

A. No. However if there is a bow in the hinge side jamb, then recessing or packing the middle hinge may be necessary.

Q. If I have a current door that I am replacing and it has the hinges that have been recessed. What do I do?

A. You can either have the hinges placed to avoid the recesses and repair the existing recesses, or have them placed exactly where they exist now.

Note: If you have them placed where they exist now it will affect the width deductions. We would only recommend this if you were measuring an existing door that you are happy with the fit.

Q. How do I measure where to place the hinges if required?

A. Top: Measure from the top of the existing door to the centre of the top hinge.

    Bottom: Measure from the bottom of the existing door to the centre of the bottom hinge.

    Middle: Measure from the bottom of the existing door to the centre of the middle hinge.
