LCN 3133-689 – Frequently Asked Questions

1) What doors is the LCN 3133 concealed closer designed for?
The LCN 3133 is engineered for interior doors up to 250 lbs. Best suited for heavy-duty commercial interior applications including office doors, conference rooms, and institutional settings. Not recommended for exterior use or high-traffic areas requiring constant heavy use.
2) How does the single lever arm track system work?
The single lever arm connects the door to a track mounted in the frame header. As the door opens, the arm slides along the track, storing energy in the concealed spring mechanism. This provides controlled closing force while maintaining a clean appearance with minimal visible hardware.
3) Can this closer be used on both left and right hand doors?
Yes, the LCN 3133 is reversible for both left-hand and right-hand door applications. The track and arm assembly can be configured during installation. Verify door swing direction before ordering to ensure proper template alignment.
4) What is included with the powder coat finish?
Standard powder coat finish provides durable corrosion resistance for interior applications. Finish is applied to all visible components including the track and arm assembly. Color matches typical commercial door hardware finishes for consistent appearance.
5) What closing force rating does this closer provide?
The LCN 3133 delivers controlled closing force suitable for doors up to 250 lbs. Closing speed is adjustable through valve controls. Confirm door weight and width requirements with manufacturer specifications before installation.
6) Does this closer meet ADA accessibility requirements?
When properly adjusted, the LCN 3133 can meet ADA opening force requirements. Closing speed and latching speed must be set according to local accessibility codes. Verify compliance with building inspector during final inspection.
7) What installation clearances are required?
Installation requires adequate header depth for the concealed track assembly. Check manufacturer template for exact clearance requirements. Verify frame construction can support the closer mechanism before cutting any openings.
8) Are replacement parts available for the 3133?
Yes, LCN provides replacement parts including springs, seals, and adjustment valves. The lever arm and track components are also available separately. Contact manufacturer for specific part numbers and compatibility verification.
9) How are closing speed adjustments made?
Closing speed adjustments are made through accessible valve controls. Use manufacturer-specified adjustment tools to prevent damage to valve stems. Make small incremental adjustments and test door operation after each change.
10) What other LCN concealed closers are available?
LCN offers various concealed closer models for different applications. Browse our door closers section for overhead concealed and surface-mount options. Consider door weight, traffic level, and installation constraints when selecting alternatives.
11) Can the 3133 be installed in existing door frames?
Retrofit installation is possible but requires careful evaluation of existing frame construction. Header modifications are necessary to accommodate the concealed track. Consider structural integrity and aesthetic impact before proceeding with existing frame installation.

    We purchased a few of these. They are great for new doors that can be prepped or if your team knows how to do the prep onsite.
