Q. What is a Triple Lock Upgrade?

A. A triple lock upgrade is a locking system that is activated from the centre locking handle position either by the chrome snib or the key and has two additional strikers at the top and bottom of the door. It makes the door more secure as there are three points where the door is locked to the frame in addition to the three heavy duty hinges on the hinge side of the door frame.

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. 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 the door jamb for a new screen door our Product Builder will guide you through how to measure the door jamb 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: The standard width deductions for single lock hinged doors is 8 mm off the widths or 9mm for a triple lock hinged door. Standard height deduction for a hinged door is 8 mm 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 at Step 3. Addons.

Q. My doors swing inside the house, do I measure from the inside instead?

A. No, always measure from the outside looking in. If your doors swing inward let us know by stating "Inward Opening" in the delivery instructions field. We will reverse the hinges.

Q. How do I make sure my locks don't hit on each other?

A. Stand outside, close the main solid door. Establish whether you want the new lock on the left or right hand side, then if you want the new lock above the existing door handle or below.

Lock Above: Measure from the bottom sill to the top of the existing solid door handle and add 125 mm: this will be the new door handle and tongue height.

Lock Below: Measure from the bottom sill to the bottom of the existing solid door handle and deduct 60 mm: this will be the new door handle and tongue height.

Q. What if I have an existing screen 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 from Step 3 in the Product Builder.

Q. Do you install?

A. No, we are a supply only manufacturer based in Newcastle NSW, we do not have a measure and install service outside the Newcastle area. If you are in Newcastle please contact Defendoor on 1300 283 918.

Q. Does the door come with a door jamb / sub-frame?

A. No. If you require a sub-frame or jamb extender to buildout the door frame please contact the office to discuss as we can supply this.

Q. Does the door come with screws to fit?

A. No. You will require either 8-gauge screws for hinges if fitting to timber or 3/16 countersunk rivets if fitting to aluminium for the hinges.

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 sill to the centre of the hole and deduct 4 mm.

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. Measure from the bottom of the existing screen door to the centre of each hinge; enter these measurements in the Delivery Instructions field in the shopping cart.

Q. What is the size of the door frame?

A. The depth of the frame is 20mm, the width of the face is 70 mm.
