Dormakaba C553-D-LRC-626 – Frequently Asked Questions

1) What applications is the DORMA C553 Grade 2 entry keyed lever lockset designed for?
The C553 is designed for light to medium commercial applications including offices, retail spaces, and institutional buildings. Grade 2 rating provides reliable performance for doors with moderate traffic volume.
2) What door thickness and backset does this lockset accommodate?
Standard installation fits 1-3/8" to 1-3/4" door thickness with 2-3/8" backset. Verify your door specifications match these dimensions before ordering.
3) How do I determine the correct handing for this lever lockset?
Stand on the side where the door swings away from you. If hinges are on the right, order right-hand. If hinges are on the left, order left-hand. Non-handed options may be available for some configurations.
4) What finishes are available for the DORMA C553 series?
Common finishes include satin chrome, polished chrome, and oil-rubbed bronze. Check product specifications for available options as finish availability may vary by model configuration.
5) What does Grade 2 rating mean for commercial locksets?
Grade 2 meets ANSI/BHMA standards for medium-duty commercial use. It provides 400,000 cycle testing and higher torque resistance than residential grade locks while being more cost-effective than Grade 1.
6) Does this lockset meet ADA compliance requirements?
Lever handles typically meet ADA requirements for ease of operation. Verify specific model compliance with local ADA standards and building codes for your installation.
7) What keying options are available for the C553 entry lockset?
Standard keyed entry function locks from outside, free egress from inside. Keying options include keyed different, keyed alike, and master key systems depending on your security requirements.
8) What tools are needed for installation of this lever lockset?
Basic installation requires drill, hole saws (2-1/8" and 1" diameter), chisel, screwdrivers, and measuring tools. Follow manufacturer's template for precise hole placement and mortising.
9) How do I adjust the latch if the door doesn't close properly?
Check strike plate alignment first. Adjust strike plate position if needed. Verify door frame is square and latch bolt travels smoothly. Some models have adjustable backset or latch projection.
10) Are replacement parts available for DORMA C553 locksets?
Common replacement parts include cylinders, levers, and internal mechanisms. Check with manufacturer specifications for part compatibility and availability for your specific model number.
11) What's the difference between this and Grade 1 commercial locksets?
Grade 1 locksets offer higher cycle testing (800,000+ vs 400,000) and greater torque resistance for heavy-duty applications. Grade 2 provides excellent value for moderate traffic commercial installations.
12) Can this lockset be used on fire-rated doors?
Fire rating depends on specific model certification. Check manufacturer documentation for fire rating compliance and ensure all door hardware meets local fire code requirements for your application.
