Hey there! As a supplier of UL Listed Door Closers, I often get asked about the difference between surface - mounted and concealed UL Listed Door Closers. So, I thought I'd write this blog to clear things up and help you make an informed decision when it comes to choosing the right door closer for your needs.
What are UL Listed Door Closers?
First off, let's quickly talk about what it means for a door closer to be UL Listed. UL, or Underwriters Laboratories, is a well - known independent organization that tests and certifies products for safety. When a door closer is UL Listed, it means it has met specific safety and performance standards set by UL. This is super important, especially in commercial and public buildings where safety regulations are strict.
Surface - Mounted UL Listed Door Closers
Surface - mounted door closers are the ones you'll commonly see on doors. They're attached to the surface of the door and the frame, usually on the top. You can't miss them; they're right there in plain sight.
Installation
Installing a surface - mounted door closer is relatively straightforward. You don't need to make any major modifications to the door or the frame. All you have to do is mount the closer on the surface using the provided screws and brackets. Even if you're not a professional, with a bit of DIY know - how, you can get it done. This is a huge plus for those who want to save on installation costs.
Visibility
One of the most obvious things about surface - mounted door closers is their visibility. Some people might not like the look of a big metal device on their door, but in many commercial settings, it's not really a big deal. In fact, in some industrial or utilitarian buildings, the visible door closer can even add to the overall aesthetic.
Durability
These door closers are generally very durable. Since they're exposed, they're designed to withstand a lot of wear and tear. They can handle high - traffic areas where doors are opened and closed frequently. For example, in a busy office building or a shopping mall, a surface - mounted UL Listed Door Closer can keep working reliably for years. Check out our UL Listed Extra Heavy Duty Cast Steel Door Closer, which is a great example of a durable surface - mounted option.
Adjustability
Most surface - mounted door closers come with adjustable features. You can adjust the closing speed, the latching speed, and even the backcheck function. This allows you to customize the door closer to suit the specific needs of your door and the traffic flow in the area.
Concealed UL Listed Door Closers
Concealed door closers, on the other hand, are hidden inside the door or the frame. You won't even know they're there unless you look closely.
Installation
Installing a concealed door closer is a bit more complex than a surface - mounted one. You need to make recesses in the door and the frame to accommodate the closer. This usually requires professional installation, which can add to the overall cost. However, the end result is a clean and seamless look.
Visibility
The main advantage of concealed door closers is their invisibility. They give the door a sleek and elegant appearance. This is especially important in high - end residential buildings, luxury hotels, or modern office spaces where aesthetics matter a lot. If you want your door to look as uncluttered as possible, a concealed door closer is the way to go. Check out our Concealed UL Listed Door Closer for a great concealed option.
Durability
Concealed door closers are also durable, but they're more protected from the elements and physical damage since they're hidden. However, if something does go wrong, it can be more difficult and expensive to repair because of their hidden location.
Adjustability
Like surface - mounted door closers, concealed ones also offer adjustability. You can still fine - tune the closing and latching speeds to ensure smooth operation. Our EN2 - EN4 Power Adjustable Recessed Door Closer With Fire Rated is a great example of a concealed door closer with adjustable power settings.
Cost Comparison
When it comes to cost, surface - mounted door closers are generally cheaper. The lower installation cost and the fact that they're more mass - produced contribute to their affordability. Concealed door closers, on the other hand, are more expensive due to the higher installation cost and the more complex manufacturing process.
Maintenance
Surface - mounted door closers are easier to maintain. Since they're visible, you can easily inspect them for any signs of damage or wear. You can also clean them without any hassle. Concealed door closers are a bit trickier to maintain. If there's a problem, you might need to disassemble parts of the door or the frame to access the closer.
Which One Should You Choose?
The choice between a surface - mounted and a concealed UL Listed Door Closer depends on several factors. If you're on a budget and don't mind the visible look, a surface - mounted door closer is a great option. It's easy to install, durable, and adjustable. On the other hand, if aesthetics are your top priority and you're willing to spend a bit more, a concealed door closer will give you a clean and sophisticated look.
