Door Closers FAQ

Door Closes FAQs

What type of door closer do I need?

That would depend on what type of door you have and what your needs are.  Selecting the right door closer is important as not all door closers are the same. Factors such as door size, weight and type all determine what closer is best suitable. The most common type of closer is a surface mounted one, but there are many types of these. 

You can start by having a look through the Lockwood Surface Mounted Door Closers Catalogue as a guide, and then contact us so we can help you choose the best possible closer for you.


What is back check?

The backcheck stalls the opening of the door around 70° to 180°. When doors are violently opened by pedestrians or wind, the backcheck feature reduces the likelihood of damage should contact be made with an adjacent wall or obstacle. For busy doors in public building, schools and colleges this facility protects people and property.


What is delayed action?

When a door is opened beyond 70° and up to 180° it can enter into a delayed mode allowing additional time before the closing. Delayed time can be adjusted to vary from seconds to minutes depending on the angle to which the door is opened. Delayed Closing Action is an advantage to people and industries such as Nursing staff assisting patients, Domestic staff pushing meals or maintenance trolleys, and the disabled and elderly or infirm walking with sticks or frames under supervision.


What is the closing speed?

The closing speed is the time frame from the start of the door closing to just before the door hits it latch point. This is between roughly 180° and 10°. This speed can be adjusted on the closer to speed up or slow down the closing of the door depending on what is needed. Although similar, this feature is independent of the delayed action, and can be adjusted to work with or without it.

Closing Sequences


What is the latching speed?

The latching zone is the last 10° of the door closing before it is fully shut. When a door is having problems with slamming or not closing fully, it is this part that usually needs adjusting.


What is a hold open or a hold open arm?

Hold Open is the ability of the door closer to hold the door in the open position. Most over head door closers achieve this function via a special type arm (Hold Open Arm). These can often be installed on an existing door closer depending on the brand and model.


I live in an apartment and I have a closer on the door which makes the door close all the time. It’s a nuisance and I’ve been locked out because of it. Can you take off the door closer?

If you live in an apartment or home unit the front door is probably fire rated and a fire exit. The door closer cannot be removed from the door because due to the Australian Standards on fire regulations the door closer has to be fire rated and keep the front door closed to prevent the spread of fire and smoke.


Our door slams all the time even though it’s got a door closer on it, can you fix it or does it need to be replaced?

Most door closers have adjustable closing and latching speeds so to fix your problem it could be as simple as adjusting one of those functions. If this doesn’t work, it could be that your closer is on its last legs and needs to be replaced. We have a wide range of door closers for all domestic and commercial situations, so just call us and we’ll find a solution for you.
