Corbin Russwin CLX3357 NZD 626 – Frequently Asked Questions

1) What is the primary function of the Corbin Russwin CLX3357 lock?
The CLX3357 is a storeroom function cylindrical lever lock. The outside lever is always locked and requires a key for entry. The inside lever is always unlocked for free egress. This function is ideal for storage rooms, supply closets, and areas requiring restricted access.
2) What door thickness does this lock accommodate?
Standard cylindrical locks typically fit doors from 1-3/8" to 1-3/4" thick. Check the manufacturer's template for exact specifications and any adjustable components. Verify your door thickness before installation.
3) Is this lock handed or non-handed?
Most Corbin Russwin cylindrical lever locks are field-reversible for left or right-hand doors. The lever can typically be rotated during installation to match your door swing. Confirm handing requirements with your door preparation.
4) What backset does this lock use?
Standard backset options are typically 2-3/8" or 2-3/4". The backset is the distance from the door edge to the center of the lock cylinder. Measure your existing door preparation or check the manufacturer's specifications for your specific model.
5) What grade rating does this lock have?
Corbin Russwin commercial locks typically meet ANSI Grade 1 or Grade 2 standards for heavy-duty commercial use. Grade 1 provides the highest security and durability for high-traffic applications. Verify the specific grade rating for your security requirements.
6) Does this lock meet fire code requirements?
The storeroom function allows free egress from the inside, which typically meets most fire code requirements. However, verify local codes and specific application requirements with your authority having jurisdiction before installation.
7) What finishes are available for this lock?
Corbin Russwin typically offers finishes including satin chrome, bright chrome, satin brass, and oil-rubbed bronze. Specific finish availability may vary by model. Check the product specifications for available options.
8) What tools are needed for installation?
Basic installation requires a screwdriver and possibly a drill for pilot holes. Door preparation requires hole saws for the cross-bore and edge bore, plus a chisel for mortising the latch and strike plate. Follow the manufacturer's template for precise measurements.
9) Can the lock be rekeyed to match existing keys?
Yes, most Corbin Russwin locks use standard IC cores or can be rekeyed by a qualified locksmith. This allows integration into existing keying systems or master key arrangements. Consult a locksmith for proper keying coordination.
10) How do I adjust the latch if it doesn't align with the strike?
First check that the door is properly hung and the frame is square. The latch may be adjustable or you may need to reposition the strike plate. Ensure proper door clearance and that the latch fully extends into the strike opening.
11) What's the difference between this and passage function locks?
Unlike passage locks where both levers are always free, the storeroom function keeps the outside lever locked at all times. Entry requires a key from outside while exit from inside is always free. This provides one-way security control.
12) Are replacement parts available for this lock?
Corbin Russwin typically stocks replacement parts including cylinders, levers, latches, and strikes. Parts availability depends on the lock's age and model. Contact the manufacturer or check with Corbin Russwin products for current parts availability.
