Allegion’s LCN 4040XP Door Closer

Aug. 2, 2022
New enhancements give installers and service technicians additional confidence in installing and adjusting the door closer properly

CARMEL, IND. (July 27, 2022) Allegion US, a leading provider of security products and solutions, has enhanced the LCN 4040XP door closer to make the already durable closer even easier to install and maintain. No internal design changes were made – the closer retains the same performance, door prep and certifications. The external-only enhancements mean installers will benefit from reduced maintenance and an improved customer experience.

“With 50 percent of facility management professionals retiring in the next 5 to15 years, it’s important for us at Allegion to meet the needs of the installers today and tomorrow,” said Yong Lacy, director of product management, Door Controls. “So, we took our most popular door closer – the LCN 4004XP – and made it even simpler to install while improving the user experience and reducing overall required maintenance. We want to continue to be the partner of choice for facility management professionals, meeting them where they are with the precise solutions they need and can trust.”

The 4040XP Series is LCN’s most popular door closer. A critical component to any opening, this durable non-handed, surface-mounted heavy duty closer, is designed for the most demanding high-use-and-abuse applications. The enhancements to the LCN 4040XP door closer include:

  • A new patent-pending positive stop staking feature that prevents screws from being backed out
  • Labeled regulation valves and corresponding diagram to make adjustments more intuitive, faster and more consistent
  • Enhanced green dial that takes the guess work out of spring power adjustment
  • LCN’s logo on the casting, which makes product identification easier

New digital resources were also added to further simplify the installation process for new facility management professionals. These include interactive installation instructions via a QR code on the closer itself.
