Dormakaba C580-D-LRC-626 – Frequently Asked Questions

1) What is a storeroom function lever lockset?
A storeroom function lockset keeps the outside lever locked at all times. Entry requires a key from the outside. The inside lever is always unlocked for free egress. Common for storage rooms, supply closets, and restricted access areas.
2) What door thickness does the Dorma C580 fit?
Standard commercial locksets typically fit 1-3/4" to 2" thick doors. Verify your door thickness against the manufacturer's specifications. Adjustable through-bolts accommodate slight variations in door thickness.
3) How do I determine the correct handing for this lockset?
Stand on the side where the door opens toward you. If hinges are on the right, it's right-handed. If hinges are on the left, it's left-handed. Many commercial locksets are reversible during installation.
4) What backset does the C580 require?
Commercial locksets commonly use 2-3/4" backset. Verify the distance from door edge to center of existing bore hole. Some models offer adjustable backset options. Check manufacturer template for exact measurements.
5) What grade rating does this lockset meet?
Commercial locksets typically meet ANSI Grade 1 or Grade 2 standards. Grade 1 offers highest security and durability for heavy-use applications. Grade 2 suits moderate commercial use. Verify specific grade rating for your application requirements.
6) Does this lockset meet ADA compliance requirements?
ADA requires lever handles that operate with 5 pounds of force or less. Most commercial lever locksets meet this requirement. Verify the specific model meets ADA standards if compliance is required for your installation.
7) What are the standard bore hole dimensions?
Standard commercial locksets use 2-1/8" diameter bore hole and 1" diameter edge bore. Cross bore height is typically 2-3/8" or 2-3/4" from door bottom. Always use manufacturer's template for precise measurements.
8) Can I rekey this lockset to match existing keys?
Most commercial locksets can be rekeyed by a locksmith to match your existing key system. This allows master keying and grand master key systems. Consult a qualified locksmith for rekeying services and key control options.
9) What tools are needed for installation?
Installation typically requires a drill, hole saw kit, chisel, screwdriver, and measuring tape. Use the manufacturer's template for accurate hole placement. A door lock installation jig can improve precision and speed.
10) How do I maintain this lever lockset?
Clean lever handles regularly with mild soap and water. Lubricate the cylinder annually with graphite or manufacturer-recommended lubricant. Avoid oil-based lubricants that attract dirt. Check screws periodically for tightness.
11) What finish options are available?
Commercial locksets commonly come in satin chrome, polished chrome, satin stainless steel, and oil-rubbed bronze finishes. Choose finishes that match existing hardware and suit the environmental conditions of your installation.
12) Are replacement parts available for the C580?
Commercial grade locksets typically offer replacement cylinders, levers, and internal mechanisms. Contact the manufacturer or check our door hardware section for available parts and service options.
