Corbin Russwin CL3857 NZD 626 – Frequently Asked Questions

1) What is the CL3857 storeroom function and how does it work?
The CL3857 provides storeroom function where the outside lever is always locked and inoperative. Entry requires a key from outside. The inside lever is always free for immediate egress. This function is ideal for storage rooms, utility closets, and areas requiring controlled access.
2) What door thickness and backset does this lock accommodate?
Standard cylindrical locks typically fit 1-3/8" to 1-3/4" door thickness with 2-3/8" or 2-3/4" backset options. Verify your door specifications and check the manufacturer template before ordering. Adjustable backset models may be available.
3) How do I determine the correct handing for this lever lock?
Stand on the side where the door opens toward you. If hinges are on your right, it's right-hand. If hinges are on your left, it's left-hand. Many cylindrical locks are reversible for field handing during installation.
4) What finishes are available for the CL3857 series?
Corbin Russwin typically offers multiple finish options including satin chrome, bright brass, satin brass, and oil-rubbed bronze. Check the specific model number suffix to confirm the finish. Match existing hardware for consistent appearance.
5) What grade rating does this cylindrical lock have?
Standard duty cylindrical locks are typically ANSI Grade 2 rated. This provides suitable security and durability for light to medium commercial applications and residential use. Verify grade requirements for your specific application and local codes.
6) Does this lock meet fire door requirements?
Check if the specific model is listed for fire door applications. Fire-rated locks require UL listing and proper installation on listed fire door assemblies. Consult local codes and fire marshal requirements for your project.
7) What cylinder type does the CL3857 use?
Most Corbin Russwin cylindrical locks use standard 6-pin cylinders. The lock may come with construction cylinders or require separate cylinder ordering. Coordinate with your locksmith or key system requirements for proper cylinder specification.
8) Can I install this lock on a hollow metal door?
Yes, cylindrical locks work well on hollow metal doors when properly prepared. Ensure door reinforcement is adequate around the lock area. Follow manufacturer templates for precise hole locations and sizes.
9) How do I adjust the latch if the door doesn't close properly?
Check strike plate alignment first. The latch should fully extend into the strike opening. Adjust strike plate position or use longer screws if needed. Verify door is not sagging and hinges are properly aligned.
10) What other Corbin Russwin functions are available in this series?
The CL3800 series offers various functions including passage, privacy, classroom, and entry functions. Browse our Corbin Russwin selection for compatible models with different operational requirements.
11) Will this lock work in high-humidity environments?
Standard locks can handle normal humidity levels. For pool areas, steam rooms, or exterior applications, specify locks with enhanced corrosion resistance or weatherproof ratings. Consider finish durability in harsh environments.
12) What tools are needed for installation?
Basic installation requires a drill, hole saws (2-1/8" for cross bore, 1" for edge bore), chisel, screwdriver, and measuring tools. Use the manufacturer template for accurate hole placement. Professional installation ensures proper operation and warranty compliance.
