Whitco Tasman Mk2

Whitco Tasman mk2 security screen door lock is the most popular security door lock used in Brisbane. It replaced the Tasman mk1 which used a more conventional latch design which had no deadlatching pin.

The Whitco Tasman mk2 has proven to be a very successful and reliable lock for security screen doors. While we do replace many of these locks on a daily basis, it is often due to the sheer number of cycles these locks have performed. A security screen door can get opened and closed a large number of times. In an average home a security screen door can get used more then 100 times a day!

One of the latest upgrades to this screen door lock is the new handle spring design. Older designs used a handle spring that would cause the handles to sag over time. While the new design has not been around long enough to test in the field, it does look like the sagging of the handles might have been fixed. Whitco often update their designs when they discover a better way to manufacture their locks.

Whitco tasman mk2 blackThe standard mk2 Tasman comes with an inside locking snib which is used to snib the door locked when inside the house. The snib is removable so the door can be only locked with the key if needed. The snib can be unlocked from the outside of the door if fingers can get through the fly screen mesh. There are plastic guard plates available to prevent fingers unlocking the snib from the outside. Solid screen doors and Crimsafe doors make it much harder to unlock the snib from the outside and give added security in this regard. The locking snib is advisable to use when at home. A key deadlocked door can be much harder to exit in case of an emergency.

The latch on a Tasman looks quite different to other screen door locks. It has the main bolt latch and a separate deadlatching latch. The deadlatching latch does not enter the main hole on the strike. This allows the main latch to fully extend only when the door is shut. If the deadlatching latch is too far away from the door strike the latch will not extend fully and the door will not be able to be locked.

carbine profile cylinderCylinders are available for this security door lock in various styles. The most popular cylinders made by Whitco are the 10 disc and 5 pin cylinder. Both these locks can be keyed alike to other screen doors in the home. The 5 pin cylinder can be keyed alike to many more locks including most Lockwood locks. The choice of cylinder can depend on the level of security needed and other mechanical considerations. Some screen doors will not work with specific cylinders.

When removing a cylinder from a Tasman security screen door lock, you must have the key. The key must be turned to the locked position then the cylinder screw is removed. Without the key the cylinder will not be able to be removed and a locksmith will need to be called to remove the lock.

A lock with 3 point locking or triple locking will require a specific mk2 security screen lock with the triple locking parts. When installing or using a triple lock door always make sure the locking mechanism is easy to operate and not binding. An unaligned triple lock door will put a lot of extra force on the locking mechanism and cause the lock to prematurely fail.

The inside locking snib can give an indication of a worn out lock. If the inside snib has lost its’ spring and flicks from locked to unlocked without a noticeable click, then the lock will need to be replaced. The failure or breakage of the snib spring mechanism can cause the lock to fail and you can get locked in or out of the house.

Overall the Whitco Mk2 Tasman has proven itself to be an efficient and long lasting screen door lock for Brisbane homes. A little lock lubricant now and then will help to keep the screen door in working condition for many years. These locks are still readily available from locksmiths and are a current model for the foreseeable future.

DIY Security Screen lock Replacement

If you have a security screen door lock that has lost its spring, has saggy handles or just broken then you will want to replace it.  Before you go to the hardware shop buy a replacement lock there are a few things you really need to know.

Number one.
Security screen door locks come in 2 basic types. Locks for sliding doors and locks for swinging doors. Make sure you buy the correct one.

Number two.
Try to match up brands. The 3 most popular brands in Australia are Whitco, Doric and Lockwood. Matching the same brand of lock will make your life much easier when it comes to installation.

Number three.
Try to match the model. If your lock is a Whitco MK2, try to replace it with a Whitco MK2. A Whitco MK1 will not work on most doors that have a MK2 lock installed and vise versa.

Number four.
Even though you have the same model lock… Look harder… Even the same model locks can be different. The same model lock can have different functions that are not suited to your door.

Number five.
Most hardware shops do not sell security screen locks for triple lock doors. If you have a Crimsafe door or other well made screen it probably locks in three places on the door. The hardware shop locks might have the same name and model but they do not work.

Number six.
If you do not have a key for the lock to remove the cylinder, consider calling a locksmith to replace the lock.  It can save a lot of time and headaches as the lock will not be able to be removed from the door.
